A SEMINAR TOPICS FOR THE B.TECH STUDENTS ON "Multiterabit Networks"

Multiterabit Networks

The explosive demand for bandwidth for data networking applications continues to drive photonics technology toward ever increasing capacity in the backbone fiber network and toward flexible optical networking. Already commercial Tb/s (per fiber) transmission systems have been announced, and it can be expected that in the next several years, we will begin to be limited by the 50 THz transmission bandwidth of silca optical fiber. Efficient bandwidth utilization will be one of the challenges of photonics research. Since the communication will be dominated by data, we can expect the network of the future to consist of multiterabit packet switches to aggregate traffic at the edge of the network and cross connects with wavelength granularity and tens of terabits throughout the core.

The infrastructure required to govern Internet traffic volume, which doubles every six months, consists of two complementary elements: fast point-to-point links and high-capacity switches and routers. Dense wavelength division multiplexing (DWDM) technology, which permits transmission of several wave-lengths over the same optical media, will enable optical point-to-point links to achieve an estimated 10 terabits per second by 2008. However, the rapid growth of Internet traffic coupled with the avail-ability of fast optical links threatens to cause a bottleneck at the switches and routers.




Multiterabit packet-switched networks will require high-performance scheduling algorithms and architectures. With port densities and data rates growing at an unprecedented rate, future prioritized scheduling schemes will be necessary to pragmatically scale toward multiterabit capacities. Further, support of strict QoS requirements for the diverse traffic loads characterizing emerging multimedia Internet traffic will increase. Continuous improvements in VLSI and optical technologies will stimulate innovative solutions to the intricate packet-scheduling task.

Routing Principles :

The principal criterion of successful routing is, of course, correctness, but it is not the only criterion. You might prefer to take the most direct route (the one that takes the least time and uses the least fuel), the most reliable route (the one that is not likely to be closed by a heavy snowfall), the most scenic route (the one that follows pleasant country roads rather than busy highways), the least expensive route (the one that follows freeways rather than toll roads), or the safest route (the one that avoids the army's missile testing
range). In its most general form, optimal routing involves forwarding a packet from source to destination using the "best" path.

A SEMINAR TOPIC ON FIREWIRE FOR B.TECH CSE & IT STUDENTS AND PG MCA STUDENTS

FireWire is one of the fastest peripheral standards ever developed, which makes it great for use with multimedia peripherals such as digital video cameras and other high-speed devices like the latest hard disk drives and printers.

FireWire is integrated into Power Macs, iMacs, eMacs, MacBooks, MacBook Pros, and the iPod. FireWire ports were also integrated into many other computer products dating back to the Power Macintosh G3 "Blue & White" computers. All these machines include FireWire ports that operate at up to 400 megabits per second and the latest machines include FireWire ports that support 1394b and operate at up to 800 megabits per second.

FireWire is a cross-platform implementation of the high-speed serial data bus -- defined by the IEEE 1394-1995, IEEE 1394a-2000, and IEEE 1394b standards -- that can move large amounts of data between computers and peripheral devices. It features simplified cabling, hot swapping, and transfer speeds of up to 800 megabits per second (on machines that support 1394b).

Major manufacturers of multimedia devices have been adopting the FireWire technology, and for good reason. FireWire speeds up the movement of multimedia data and large files and enables easy connection of digital consumer products -- including digital camcorders, digital video tapes, digital video disks, set-top boxes, and music systems -- directly to a personal computer.

In fact, Apple's FireWire technology was honored by the Academy of Television Arts & Sciences, receiving a 2001 Primetime Emmy Engineering Award for FireWire's impact on the television industry.

A SEMINAR TOPICS FOR THE EEE STUDENTS ON "1xEV-DO Architecture for Wireless Internet "

Millions of people around the world use the Internet every day -- to communicate with others, follow the stock market, keep up with the news, check the weather, shop, entertain themselves and also to learn. Staying connected has become so important that it's hard to get away from our computer and our Internet connection because we might miss an e-mail message or any news we need to know.

With the world's business and people's personal lives growing more dependent on communication over the Internet, we must be ready to take the next step and get a device that allows us to access the Internet on the go.
