If you are a technologically-savvy person, thinking of new and exciting ways to expand your brand online may come naturally. For those who are new to the IT world, the idea of relying on the Internet to promote your business or product may seem a little overwhelming, to say the least. With more and more companies using their websites to draw in potential customers, there are many different factors to consider if you’re hoping to stand out from your competitors in an online environment.

One of the most common mistakes new website owners make is to excitedly promote their site without thinking about its design and layout beforehand. Is your company name clear and visible at the top of the homepage? Does your color scheme match your company logo? Do you have any mission statements or catch phrases that you could use somewhere on the homepage?

Before you start thinking of elaborate design ideas, remember that the key to website design is to keep it simple. If you want visitors to subscribe to a newsletter or purchase one of your products, they should be able to navigate their way around your website without any confusion. If you are hoping to have an online store on your website, make sure visitors can access it from the very top of the homepage as well.

Once you have finished figuring out the design of your website, your next step is to expand your online presence to various social media platforms. We are not just talking about Facebook and Twitter.  Pinterest, Google Plus, YouTube and LinkedIn are all excellent networking sites which are used by business owners to promote a website or company. If you have a blog section on your site, then be sure to submit your posts to Stumble Upon, Digg and Reddit.

And last, but certainly not least, if you use your website for commercial purposes, it may be a good idea to switch to a private cloud provider, if you haven’t done so already. In doing so, all of the data stored on your website is kept safe and secure, which is incredibly important if customers are required to enter sensitive information into your site’s database.

Try talking to other business or website owners to see what kind of hosting platform they recommend. You could even try checking out any upcoming technology expos or conferences in your area as well. The Scalematrix Technology Symposium, for instance, offers a variety of panel discussions, lectures and workshops to educate attendants on the latest in technology and hosting services.

With the World Wide Web constantly changing and evolving, as a business owner you should always be trying out new and exciting ways to reach out to potential customers. Remember that the key in maintaining an online presence isn’t just about finding new customers, you also want to encourage people to come back to your website as well.

Microsoft Surface first started back in 2001 under the code name “Milan”. It was a project that was started by a very small group of Microsoft employees. The design was changed 10′s of times, but was finally presented to Bill in 2003. Of course, Mr. Gates liked it, and the project took on new life as it grew. By 2005 the final design had been chosen, and in 2007 it was presented to the public. The public was in awe, and Microsoft was proud.

So what makes Microsoft Surface so unique? It is unique because it goes where no computer has gone before. It uses a Natural User Interface (NUI). An NUI is an interface that attempts to take out any space between the digital and real world. It makes digital information and data seem real, by using Multi-touch interaction. Mult-touch interaction is simply a touch screen that supports multiple input points (touches) at the same time.

In fact, Microsoft Surface supports up to 52.

Multi-touch is the biggest part of a Natural User Interface. It makes tasks such as viewing pictures… natural. There is practically no learning curve. To move a picutre, you simply put your finger down and drag it to the desired location, and to resize a picture simply pinch the picture with two fingers.

Another part that makes Surface’s interface natural is the object recognition feature. Object recognition has three parts to it.

The first part is the ability to recognize more than just fingers, which means it can recognize objects. This is different from normal touch screens because normally touch screens require an electric current or heat, which come from fingers. However, unlike those touch screens, Surface does not care whether it is a finger or a Zune.

Second, the use of byte tags allow for unique object recognition.

By simply creating a relation between a specific byte tag pattern and an object, such as a camera, the Touch Table can recognize that that object is a camera.

Thirdly, Surface can transfer data via Bluetooth between certain digital objects. When you set the camera down, Surface recognizes it as a camera through the byte tag, and then opens ports for data transfer. Then, to transfer photos on to the camera, you simply drag them to it. And when you set the camera down at first, the photos dump out onto the Surface table top.

All these factors make Microsoft Surface’s Natural User Interface truly amazing and state of the art.

Abstract:   This paper, the development of the global optical network situation is briefly introduced, then elaborated on some form next-generation optical networks and the corresponding key technologies.

Keywords: Metro optical networks; long-distance optical network; Multi-Service Transport Platform (MSTP); Resilient Packet Ring (RPR); Multi-protocol Label Switching (MPLS), wavelength division multiplexing (WDM); Raman amplifier ( RamanAmplifier); Automatic Switched Optical Network (ASON); Generalized Multi-Protocol Label Switching (GMPLS)

1. Overview End of last century, the new century, the global telecommunications market had a bubble, optical networking market was a serious recession, operators are no longer blind pursuit of high capacity and high bandwidth, but more emphasis on capital expenditure (CAPEX), operating expenses (OPEX) and return on investment (ROI) and other financial indicators, more value system equipment performance and low cost, multi-business solutions more attention, more attention can save labor costs of the intelligent configuration and scheduling function.

After several years of sharpening and the shock, since 2004, signs optical networking market, particularly evident.

Optical network is a basic network, after all, once the business grew, the bearing pressure optical network will increase accordingly. If the pursuit of long-haul optical network with high bandwidth, large capacity, then the pursuit of metro optical networks are multi-service and flexibility. So far, the global long-distance optical network bandwidth becomes saturated or even excess carriers in long-distance optical network investment ratio decreased or remained stable.

However, due to the urgent need for practical engineering, ultra-long distance transmission which has evoked strong concern about some of the technical bottlenecks have been resolved, the pace is accelerating business. In addition, including the storage network (SAN) business, including data services is rising, image and multimedia services rather potential, will amount to anything. Many operators are moving in multi-service operator (MSO) the direction of evolution, voice, data and image go hand in hand makes the “TriplePlay” the word is very compelling. Construction of metro operators in full swing, the real purpose is to achieve network optimization is aimed at long-distance backbone network and access network between the user remove the “fault” phenomenon. We know that Metro is the metro optical network business network carrier, if the optical network (such as the traditional SDH and WDM) is only “fool” to send a business signal, then the business layer of pressure would be enormous. Now, the incumbent operators are building networks to modify their thinking, new operators is one step, adopt a new generation of optical networking equipment with the joint network service layer equipment.

2. On the next-generation optical network

Not mentioned here, the next generation of optical networks is to allow everyone to think that is a long way off. In other words, a new generation of optical network seems more practical, more relevant.

As voice services and TDM services can not instantly disappear, “a new generation of SDH” despite being classified as transitional technology, but it does have the vitality, the kind of “SDH degraded from a system to an interface “too early to say, especially for the Third World and less developed regions have operators. Two features is the new generation SDH multi-service and intelligent, multi-service performance evolved from SDH MSTP, intelligent performance as the introduction of GMPLS / ASON control plane to realize flexible bandwidth allocation, the business end scheduling and dynamic protection and restoration of function.

Has been the requirements of the industry is high-capacity WDM and transparent transmission. But the new generation of WDM equipment, other than to provide large capacity, high bandwidth, long distance transmission, while also providing rapid multi-service access and its own optical layer protection.

3. On the next-generation WDM networks

Long distance transmission is the next generation WDM network one of the key technologies. At present, the worldwide well-known optical communication system vendors offer large capacity, ultra-long distance DWDM transmission systems to support SDH / SONET / GE and many other business interface, the capacity can be smoothly extended to the T-bit level, the wavelength range covering C + L band can be G.652, G.655 fiber to achieve thousands of kilometers of radio relay transmission. The key technologies include: Distributed Raman and EDFA hybrid amplifier technology, super-band FEC technology, NRZ and RZ modulation pattern, dynamic power balancing, distributed dispersion management technology. Among them, the distributed Raman amplifier with large gain bandwidth, gain flatness, the distribution can be adjusted according to signal characteristics of the gain spectrum. Currently, the new standard for the Raman amplifier has been G.665 ITU-TSG15 allowed to pass through.

One of the highlights next-generation WDM network that is unique for the metropolitan area has many designs, including multi-service OTU, T-MUX, optical layer protection. For example, Metro WDM can not rely on the client layer (eg SDH) protection switching facility, which has its own recovery to share with the section of the protection and optical channel shared protection. Some metro OADM equipment serial / parallel optical switch integrated design approach, using a unique “upgrade interface” real guarantee “online upgrade” will not interrupt existing business. In addition, for the metro access network applications, operators can choose a compact, cost-effective CWDM equipment, enabling rapid capacity expansion and network optimization.

4. On the next-generation SDH network

About next-generation SDH, we naturally think of MSTP equipment, it can be based on a variety of SDH line rates to achieve, including 155Mb / s, 622 Mb / s, 2.5 Gb / s and 10Gb / s and so on. On the one hand, MSTP retains the inherent cross-SDH capabilities and traditional SDH / PDH service interfaces, TDM services continue to meet the demand; the other hand, MSTP provides ATM processing, Ethernet transparent transmission, L2 Ethernet switching, RPR processing , MPLS processing capabilities to meet the convergence of data services, carding and integration needs. Currently, the most preferred GFP MSTP to provide excellent package of order, and virtual concatenation and LCAS are adapted to the different needs of bandwidth and can in some particles within the link capacity adjustment. In addition to Ethernet functions, MSTP the RPR feature the original Ethernet switching module to overcome the disadvantage of slow, can achieve quick within 50ms protection switching, in addition, RPR provides a fair method to ensure the link bandwidth rational use, to maximize the situation to prevent link congestion. The use of MPLS functionality can MSTP networking capability extends from the ring lattice network, you can pseudo-wire (PW) approach to multi-client services (including Ethernet, ATM and frame relay) to access and together, and through

Abstract ASON technology is the development of optical transport network a major breakthrough, the paper discusses the advantages of ASON networks as well as the relationship between SDH and OTN, ASON is discussed in detail the transmission plane, control plane, and network management features and progress of the plane, and finally for the optical transport network evolution strategy to the ASON may be analyzed.

  Keywords automatic switched optical network user network interface synchronous digital sequence quality of service

2000 years later, the optical transport network technologies there are new developments, mainly automatic switched optical network (AutomaticallySwitched OpticalNetwork, ASON) the emergence of its most prominent feature is the introduction of an independent transmission network intelligence control plane, control plane to complete the routing using automatic discovery, call connection management, protection and restoration, so as to implement the dynamic call connection to the network management.

ASON draws heavily on the exchange and data technology, to exchange, transfer and data in three areas has added a new intersection. Various manufacturers and operators of the technology have been given due attention. This will be the key technology and its progress ASON discussed in detail and based on current national transmission network operators, the characteristics of the technical evolution of the program may be discussed.

1 ASON technical characteristics 1.1 ASON advantages ASON is a service request initiated by the users, automatic routing, signaling control achieved by the connection establishment / removal, financial exchange and transfer as one of the next-generation optical network.

Combined with the domestic transmission network operator status, ASON technology can solve the transmission network into three major technical challenges faced:

(1) the issue quickly to provide circuit

ASON most important feature is to quickly provide the circuit, using a distributed control can provide orders of magnitude in the second end of the circuit, the rate for 155Mbit / s, 2.5Gbit / s and so on. Businesses reduce the time help operators gain more customers and profit.

(2) transmission circuit QoS issues Transmission circuit current level of basic services can not be developed in accordance with the appropriate tariff policy, resulting in waste of resources, and ASON on the circuit can easily divide the priority to provide a service level agreement (SLA) of transmission circuits.

(3) can provide fast protection and restoration

Mostly rely on existing transmission network SDH rings to be protected, but the circuit efficiency is low, only 50%, while on the cross-ring circuit can not be effectively protected. The ASON can effectively solve the circuit protection and restoration can be completed in the second magnitude, and the cost of spare circuit less resources, general resources for the work of the circuit for 30% to 60%, well below the SDH ring network.

1.2 ASON and SDH, OTN relationship

Automatically switched optical network is divided into transmission plane, control plane and management plane in three parts. Transmission plane including the exchange of entities from the transmission network composed of network elements, is the realization of the connection establishment / removal, exchange and transfer of the physical plane. The introduction of ASON control plane is different from the traditional transport network is a fundamental point, which includes a series of real-time signaling and protocol system to realize the connection establishment, release control and monitoring, maintenance and other functions, the signaling control plane network support. Management plane is the control plane and transmission of the management plane.

ASON control plane is suited to the OTN (optical transport network), also applies to SDH, the transmission network as a unified control plane. SDH, OTN and ASON in the relationship can be expressed in Figure 1.

Can be seen from Figure 1, a separate SDH / OTN and does not constitute ASON, to constitute the ASON must SDH / OTN + plane + next-generation network management control plane (management and control can also plane and the transmission plane), three are indispensable. SDH, OTN transmission plane only ASON technology, ASON and SDH, OTN and does not contain relations.

2 ASON Technical Development 2.1 Technology transfer plane As the current line rate

reached 1.6Tbit / s, line capacity issue has been resolved. Transmission plane sent the most prominent problem is the node that the transmission network in the optical / electrical cross-machine, optical / electrical cross-machine is the core of transmission plane, the size of its processing capacity related to the ASON throughput and processing power, particle size .

Wavelength cross-current to achieve high capacity in three ways: The first is the all-optical switching, the second is the use of O / E / O (optical / electrical / optical) processing to achieve, the third is the photoelectric hybrid method. All-optical methods due to its stability and fault detection and location problems, is still in the experimental stage, commercialization will take some time. The opto-electronic hybrid approach the challenges facing the same way with all-optical. Now it seems the use of optical / electrical / optical approach is the mainstream product, especially in SDH-based optical / electrical / optical cross-machine (can be cross-VC-4 level). With the advent of large-capacity cross-chip (currently single cross-chip can reach 160Gbit / s and above), the core cross-cutting capacity of Tbit / s is not very difficult. To the market has been commercial-oriented 1.28Tbit / s products as an example, assume that input and output ports of the processing rate of 10Gbit / s, the cross-matrix of size 128 × 128 should be more than the capacity of its external service access 1.28Tbit / s. This rate of capacity is appropriate for the current network, although route on the backbone WDM System is 32 × 10Gbit / s, but the actual with the wavelength is usually 4 to 8, assuming that each line has eight wavelengths need to be processed, the matrix can be cross-direction of the end of the 16 WDM line. Even for such a core transmission node Beijing, currently meet the requirements. Using optical / electrical / optical mode is a characteristic of other low-level VC can cross to achieve a low rate of integration and aggregation, network more easily.

Optical / electrical / optical methods can support high-capacity cross-Machine VC-4 and VC-4-Xc level crossing. In the external interface is generally 2.5 Gbit / s, 10Gbit / s, can be G.707 SDH interface or G.709 OTN interfaces. SDH interface supports 2 fiber, 4 fiber MS-Spring multiplex section protection ring. As the connection status monitoring by the sending side must initiate the connection point and end point detection signal quality; for SDH, OTN, you can use SDH, OTN overhead for performance monitoring and fault management, such as SDH monitoring bytes B1, J0 , control surfaces need

Tally web interface involves the interaction of various networks components which are one or more server farms, web server and client device with browser. Group of server can be controlled with single entity is the server farm. The server will access their Tally sheets with others requiring the username and passwords confidentially. The Tally sheet can be modified by the user owner and some of the rows or columns only can be modified or updated by the shared clients. Clients can any number but the owner of the Tally interface is the single entity. To communicate with server farms, there are some platform programs to be used like HTML. In web server, the authentication is the main part for accessing the Tally sheets. Authorization is given by the web server when the authentication is confirmed. There is a default option to connect web server for accessing the Tally using Tally web interface option. Client device must provide web server to access the internet connection for viewing, modifying or updating the Tally sheets. Client device can be installed in the method called web-based client installation in which deploying clients from the web sites. In can also detect presence and absence of the prompt user and the potential installed clients.
 
In this fashionable era, each on-line application has innovation technologies that are helpful for the business person yet as general purpose for the folks. Tally net interface gave several screen patterns which offer a good-looking output. The screen patterns are as follows, Page Grid that is employed to arrange the content, imagery, alignments and apply divine proportion conjointly basic style principles. the essential principle style pattern ought to exist

Multi user are often identified by initiating favorite colours to their that highlight on the proper high with the standing data. Vertical navigation bar could be a straightforward tree structure with vital few links. Horizontal navigation bar is best for links that are subjected to be permanent. there’s a lot of choice is offered in Tally net interface.

Communication has always been an integral part of society. In the past century or so there have been a number of developments that have revolutionised the way in which we can communicate. For instance, the telephone made long distance communications effortless, or the Internet, applications such as skype now allow us to actually talk face to face on a virtual level. However it is in the last decade that technology has really began to drastically change how we communicate, not just with each other, but with computers too.

Nowadays you might email a question to a co-worker that is in a cubicle next to you. Or attend a virtual meeting on the web to exchange information. And before getting home you may text your flat mate to see if anything needs picking up from the store. While these methods for communication may be efficient, has technology stained the art of communication? With the younger generations choosing mediums such as Facebook or Twitter for their social conversations you can’t help but wonder whether they will develop the adequate interpersonal skills that they will require as adults? They’re not using their voice, they’re just typing on a keyboard.

Well this is all about to change as natural user interfaces; also known as gesture based computing, becomes a reality.

We’ve all seen these types of interfaces before in films, where special agents will manipulate a three dimensional image with their hand or implement a complex set of instructions through a simple voice command. While we’ve still got a long way to go before we have anything like the computer interfaces in Minority Report, there is still potential there.

The Nintendo Wii has already began leading gamers down this path, and soon Microsoft’s Kinect technology will be available as an add on to the X-Box 360 console. Kinect will include full-body 3D motion capture, in addition to facial and voice recognition features, this means you will be able to control your Avatar through a simple gesture such as a wave, a nod, or a simple spoken “No”. This type of gesture technology is slowly finding its way into so many parts of society, including the business world and the education system. Efficient communication between man and machine has so many implications for so many aspects of life. In education it promotes interactive learning through understanding and reasoning, in the business world it could save huge amounts of time by eliminating keyboard or barcode scanning, and in the arts it could further potential for expression.

The flash advertisements are creating problem to the interface of websites. The end user is getting covered up and broken interface because of flash ads. We needed to stop publishing these ads to provide better interface to the end users. Most of the sites are facing this problem of covered and broken interface due to flash ads. The site owner is unable to fix this problem of interface of websites. The ad networks had been convinced to make changes to their flash embeds codes. The ad networks are suggested to simply set wmode to transparent or opaque on flash embeds to overcome this problem. The wmode is a parameter which is used to specify how a flash object is rendered on a webpage. FlashHeed can be used if the Flash Ad is not in an iframe.

web application developmentis being done all over the world by various web developers. The various technologies asp.net, php, Ajax, web2.0 are used to develop web applications. Web developers around the world are facing the same problem of breaking the web interface due to flash advertisement. The internet campaign who demanded to stop flash advertisement has a form where people can submit screenshots of offending Flash ads.

There is one major issue in changing the wmode parameter in Flash embeds from “window” to “transparent” or “opaque”. It will slow down the speed of CPU. So it is recommended either to use HTML5 or adobe to fix flash to resolve this issue.

A NIC (network interface card) is designed to speak over a computer network. It allows users to attach to every different either by using cables or wirelessly if the NIC could be a wireless NIC (WiFi/WNIC). Each entity on a network, a PC, printer, router, etc., that desires to communicate with other devices should have a NIC if it is to speak over the network. On older computers, the NIC is most likely an growth card, typically PCI or PCI express. High performance cards will value less that . NIC functionality is now usually integrated into the motherboard chipset or implemented with an infatuated Ethernet chip on the motherboard.

An analogous scenario is true for laptop computers. At just the once, a PCMCIA network card would be employed in a laptop pc for the NIC just because the PCI card was utilized in desktop pc, however currently, NIC functionality is usually integrated with the motherboard.

Ethernet is that the dominant normal for cable connections for wired computer networks.

An Ethernet connector looks almost like a telephone connector, solely larger. This connector is termed “RJ45″. Ethernet cables are either a shielded or unshielded cable of four twisted pairs of twenty four AWG connectors, specified at a hundred ohm impedance. Maximum cable length for CATX cables is a hundred meters.

Early versions of Ethernet cables were CAT3 or CAT4 (CAT being short for category). These versions weren’t long lived. CAT5 and CAT5e are currently the most commonly used cables (bandwidth of a hundred MHz, a hundred Mbps), with CAT6 (bandwidth of 250 MHz, 1 Gbps) out there and the configuration of the near-future. A CAT7 cable (bandwidth of 600 MHz) specification is in development, and ought to be obtainable in an exceedingly few years.

Every Ethernet NIC has a distinctive serial range called a “media access code” (MAC address) that’s used to spot the NIC and associated laptop on the network. No two NIC will have the same address, as a result of the NIC makers should purchase blocks of addresses from the Institute of Electrical and Electronics Engineers (IEEE).

NIC cards are capable of various speeds. Speeds of up to one gigabit per second (Gbps) are now available. 2 NIC will communicate if they differ in speed ratings, but they can communicate at the rate of the slower NIC.

On a very simple network, NIC will be used to link personal computers (PC). If the computers are connected directly to at least one another, the network is a “peer-to-peer” (P2P, additionally referred to as an “circumstantial”) network. If computers are connected directly to 1 another, a “cross-over” Ethernet cable is required (additionally referred to as a “Null-Modem cable”). This cable is not “straight-through” like customary Ethernet, however crosses the send and receive connectors, so that send line from pc A connects to the receive line of laptop B.

For networks of a few computers, a “hub” will be used, with all of the computers connected to the hub. Any message sent from any PC will be seen by all of the computers, however solely the computer with the correct MAC address will receive the message. P2P networks are helpful for many purposes. File and printer sharing are the foremost common applications.

Networks with more than four active computers at a time can benefit from employing a “network switch” rather than a hub. A network switch can direct the message to the acceptable destination, instead of each message packet being broadcast across the network. Laptop A will send a message to pc B, whereas simultaneously, pc C sends a message to pc D. This increases the efficiency of the network. This is a easy kind of a server network. An example of a client-server style is a computer server where the purchasers initiate a download or upload of files and therefore the server reacts. The server would also typically be accountable for interacting with printers and different servers on different networks, including satellite networks (SATCOM) or the Internet.

“Latency” is that the delay caused by a network to communicate data. Latency causes not solely slow service, however will result in information loss as well. Latency is typically tested by sending a message packet that is immediately returned to the sending computer. The round-trip time is defined as the latency.

Networking performance will be optimized for either latency or throughput. Networks will use a way known as “interrupt moderation” to increase throughput and lower CPU utilization by queuing message packets and issuing fewer interrupts to the CPU. A network optimized this method would favor large transfers, reducing transfer overhead. CPU and network throughput benefit, however network latency would increase. The alternative is to fragment every message and pipeline the fragments through the network. Multiple methods from supply to destination will permit overlapping. Latency will also be addressed with techniques like prefetching (anticipating the requirement for knowledge requests) and/or using multiple execution threads (multithreading).

There are two indicator LEDs on a typical NIC. One lit inexperienced LED indicates the pc is connected to the network. This can be called the “link” light. The second LED is amber in color. A flashing amber LED indicates message packet collisions are occurring. Occasional collisions are traditional on a busy network, but a frequently lit amber LED is a sign of problems. A quickly flashing link LED (green) could be a network activity indicator, that means that communication is occurring. If the inexperienced link lightweight is off, and also the amber LED is blinking, then the NIC is in “power save” mode.

A wireless network interface controller (WNIC) could be a NIC for connecting to a wireless network (WiFi). The quality for WiFi is IEEE 802.11. A WNIC uses an antenna to speak with an Rf signal, most typically at 2.4 GHz. Wireless connectivity development in recent years has closely paralleled wired connectivity. Like its wired cousin, a wireless card was once integrated with a PCI or PCMCIA add-on card. Now, integrated WNIC’s are changing into common, especially for laptop computers.
