Optical burst switching is a promising solution for all optical WDM networks It combines the benefits of optical packet switching and wavelength routing while taking into account the limitations of current all optical technology In OBS the user data is collected at the edge of the network, sorted based on destination address,and grouped into variable sized bursts Prior to transmitting a burst, a control packet is created and immediately send toward the destination in order to setup a buffer less optical path for its corresponding burst After an ....etc

With in today's Internet data is transported using wavelength division multiplexed (WDM) optical fiber transmission system that carry 32-80 wavelengths modulated at 2.5gb/s and 10gb/s per wavelength. Today's largest routers and electronic switching systems need to handle close to 1tb/s to redirect incoming data from deployed WDM links. Mean while next generation commercial systems will be capable of single fiber transmission supporting hundreds of wavelength at 10Gb/s and world experiments have demonstrated 10Tb/shutdown transmiss ....etc

It was not so long ago that switches were used in telecommunications primarily for placing telephone calls. Dialing a telephone number activated a series of switches to set up a voice path that could be as simple as the next office or as complex as a multinational conference call. Internetworks and the Internet are beginning to provide similar services for PC workstations, servers, and mainframes. The primary goal of any data network provider is to eliminate geographic and media constraints on connectivity while maintaining control ....etc

Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year.

Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit the bandwidth of a network. Optical switches at the ....etc

PRIZMA SWITCHING TECHNOLOGY

The Internet has established itself as a worldwide communications medium for a broad spectrum of communication modes: data, voice, and video?both asynchronously and in real time. Its growing popularity for entirely new applications in the field of e-business and entertainment, as well as its emerging use for well established applications such as telephony, have resulted in a spectacular annual growth factor of at least 4 (and rising ) for traffic carried by the net. The Internet is able to grow at this enormous ....etc
