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

In Your Face!

Online networking works, but relationships are the most important part of the process. Using the Internet to exchange ideas, share knowledge and increase visibility will only become more essential in the coming years. Online networking is really catching on in business and professional circles.  However, face-to-face networking isn’t going away, but is augmented by its online brethren.

A key point to remember, face-to-face networking groups continue to expand. The huge growth of BNI (Business Network International (http://www.bni.com/) bears this out. Since the Internet first became popular in the mid 1990s, BNI has experienced more than a 1,000 percent growth rate.  This stat tells you that its here to stay.

Technology in this case is meant to provide opportunities to improve your networking efforts–not replace them.

People who understand this will use technology effectively to enhance relationships and make their network reach expand dramatically.

How to handle large crowds of people where you know No One!

Sooner or later in your business career you have to attend an event where you don’t know anyone, but you have to trade business cards and carry referrals.  Remember, the goal is to collect a business card and follow up at some point with this person for a sales/business opportunity.  Also you want to make enough of an impact that this person will recommend you in their circle.

Let us say you are at your local Chamber of Commerce, your industry conference, or other large organization where you need to connect with people but obviously you can’t do that with 300 or 400 people.  The first tip is “chunk it down”.

There are several hundred people there but they are mainly in groups of 2-5.

Be strategic.  Make sure you are clear why you are attending, what you want to get out of it, and most importantly what are the other attendees there for?  Second, practice how you will incorporate yourself into a group while there. In other words have an opening line.

For example, state your FULL NAME and your company.  Come up with several benefits and try them out one at a time.  For example I have been successful using “I am with an Internet company that specializes in partnering with media companies to use search to drive more online revenue.”  Not exceptionally creative but straight to the point in a room full of online publishers.

If you see someone alone approach them.  It is very likely they will be relieved that someone did.  Remember, face-to-face connections take a lot of time and effort so decide which will be ongoing personal versus electronic.  More on this point later.

Two Heads are Better Than One

Practice ahead of time.  Be on the same page and understand what each other’s opening pitch is.  Also stand in an “open position” with the other person.  Don’t close others off. Stand and talk to the other person, but face the room and not each other.  This way it’s an invitation to speak with someone who comes up or who is alone with no one to speak with.

Please Don’t Snub Me

None of us wants to be snubbed but unfortunately sooner or later we all are and we need to go on from it.  Luckily enough professional people are rarely rude to others for the simple reason it is not good business to gain that reputation.

When networking in business or in your personal life take the high road and simply excuse yourself and tell them to have a good day.

Must Do’s and Must Have’s

Always have enough business cards.  Don’t go running around just thrusting cards at people.  It is considered rude and bad form at best.  Have a conversation before EXCHANGING cards.  If they don’t have one, write down their email and phone.

Make note on the back of their card why you are getting back to them.

Invest in your own name tag if you are attending a number of functions frequently.  This way your name and company is clearly visible and spelled correctly.  You can purchase a name tag at Staples(http://www.staples.com/).

On the follow-up remember that you will have to remind them who you are, where you met, and why you are following up with them.

Don’t forget if you are connected with someone by a third party or referred by another person to thank the connector via personal touch (phone call, card, etc).

Referrals are and will be, for the foreseeable future, all about relationships. Whether they are relationships built online or face-to-face, they will still involve relationships. People refer people they know and trust. They will not regularly refer someone just because he or she is listed on a website. That’s called advertising, not networking.

Part II will be online networking.  Who to use and why.  How and when to use LinkedIn, Facebook, Twitter, etc.

A Master of Science in Information Technology is a post-graduate degree program that aims to produce skilled professionals armed with knowledge of the core principles underlying computer science and an understanding of emerging industry trends.

Providing an academic base in Information Technology and allied subjects, the MSc. (IT) program aims to transform working professionals into specialists of technology and management. An online MSc. (IT) is open to graduates who would like to gain advanced technical knowledge to be able to combine business analytic with IT. An MSc. (IT) degree not only offers an in depth understanding of basic business applications, it also enhances one’s skills that are relevant to a changing IT scenario. An online MSc. in information technology has become popular because it offers an immediate advantage to an existing career.

With this post graduate program one can develop expertise in software development and business applications that have become imperative to organizations across the globe.

Subjects under this degree program include communications, programming paradigms, algorithms, network programming and software engineering. An MSc. (IT) degree equips a manager to undertake planning, budgeting, design, integration and deployment of strategic enterprise technologies that have become central to the working of all organizations.

This course has become particularly popular because of the recent demand in the industry for technology management along with people management. Almost turning into a definition of success, this combination is supported well by a master’s in information technology.

Employment opportunities for computer and information system managers have shown an upward trend with newer applications driving the need for more workers and, therefore, more managers. This degree program not only focuses on information technology, it also promotes business leadership. Therefore, team building, change management, and interpersonal communication make up important curricula of any master’s of science in information technology degree.

With an MSc (IT) managers are successfully able to write business strategies, set operational goals and create industrial benchmarks. They have the ability to align online MBA in Information technology for better business growth. This inevitably leads to enhancement of the bottom line for any modern-day organization.

This program can assist IT professionals as well as managers from other disciplines to develop on their area of interest. The aim of a master’s in science of information executive mba online degree is to create individuals who have sound technical knowledge and are self-motivated enough to progress with the rapid changes that this dynamic field is witnessing.

Besides lack of broad based training in natural sciences, there are other problems that discourage research. We are not training students to have enquiring minds, which is important for developing research temperament. The level of practical student undertake in science subjects at the undergraduate level remains poor. Our science academies are promoting summer project work for our young students. This is a welcome step. However, due to a limited number of scholarships only few students are benefiting. The programme will hopefully expand. Students need to be encouraged to be inquisitive and question existing notions. To some extent, the problem lies with our societal structures. We encourage rote-based knowledge that already exists rather than encouraging search for new knowledge.

The most important consideration should be the integration of science and technology. we have created boundaries between science and technology and between physical sciences and biological sciences. Even in the management of higher education, the All India Technical Council of Education (AICTE) look after technical and professional and university Grants Commission (UGC) looks after science education. We should either merge these entities or allow both to look after science and technology in the institutes associated with these bodies. If we separate science from technology are getting complicated; without integrating technology with science we will not be able to translate research into tangible products and create value.

As an example breeding superior crops for ushering in a second green revolution requires both knowledge of basic and applied biology. Future breeders will require a sound knowledge of molecular biology, genetics, biochemistry, mathematics and statistics, skills in computational work and handling laboratory equipment. Unfortunately, such education is not being imparted nor are there concerted efforts to create interdisciplinary teams to use the knowledge of molecular biology and genomic to produce novel seeds, which would require lesser inputs of water and chemicals and provide higher yield as compared to the present varieties and hybrids.

To take an example from chemistry, those who want to research new drug molecules or pesticides need some knowledge of biological sciences as a large number of chemical are being synthesized and studies for use on biological entities. Research in the field of nano-materials requires a sound knowledge of both chemistry and physics and a feel for technology.

To create a strong science-technology interface at the University of Delhi, we have initiated three M Tech courses-nuclear physics and process development—to train students in areas that require knowledge of both science and technology. Students with undergraduate degree in natural sciences are admitted in these three-year courses. We hope this will set a new trend in the country in developing a strong science-technology interface.

To develop good faculty in sciences the best of PhDs from India, around 200 every year, should be sent abroad from our own national resources to train them in areas where we want to develop strong research and development efforts. Few engineers are currently doing doctoral work in our universities and institutions for teaching of engineering subjects and also for the development of products.

Every year around 200 B-Tech students should be sent abroad for doctoral work. Scholars sent abroad from public resource should return to serve as faculty in our newly-planned universities and institutes. Otherwise the Centre’s laudatory efforts to create world-class university would go waste due to lack of first-rate faculty at the proposed universities.

Focused Projects

India student’s interest in science will improve if we initiate major research programmes relevant to India and incorporate the latest knowledge from global research in these programmes as go along. Take the example of agricultural research, I am convinced if students who have a background in the fundamentals of natural sciences will take up problem related to our major crops, India can turn the corner in agriculture productivity. We should learn from China in this aspect. China’s production of food grain is around 440 million tones. In comparison our production is hovering around 210 million tonnes for the last 10 years. In 1947 when we become independent China’s agriculture was in no batter condition than ours. China enhanced production in agriculture as agricultural research and development was given high priority and was organized in a better fashion.

India is the largest milk-producer in the world, but it also has the largest cattle population of the world. India need to increase per animal productivity. Strangely, there is no systematic programme to carry out genetics and genomic based breeding work on the improvement of cattle productivity and health.

There is a need to have big projects in agriculture, energy and materials. Research in agriculture needs to be organized on the lines of the work being done in space science or nuclear science. In the field of health, low cast diagnostics and development of low cost equipment needs to encouraged.

This required both science and technology. Development of drugs based on bio-molecules or through chemical synthesis needs to be promoted. This area also requires good scientific knowledge and a flair for technology development and collaboration with industry.

To sum up, we need broad-based training with emphasis on practical work at the undergraduate level for students of natural sciences; we need to create a strong sciences-technology interface, funding agencies need to be more proactive and focused in funding research and development needs to be encouraged.

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.
