Passive and active optical bit-pattern recognition structures for multiwavelength optical packet switching networks

Passive and active optical bit-pattern recognition structures for multiwavelength optical packet switching networks.

Next generation High-Speed optical packet switching networks require components capable of recognising the optical header to enable on-the-fly accurate switching of incoming data packets to their destinations. This paper experimentally demonstrates a comparison between two different optical header recognition structures; A passive structure based on the use of Fiber Bragg Gratings (FBGs), where...

Optical Label Switching Technologies for Optical Packet Switched Networks

Techniques for Optical Packet Switching and Optical Burst Switching

Wavelength-division multiplexing appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. Several different technologies have been developed so far for the transfer of data over WDM. In this article we survey two new technologies which are still in the experimental stage — optical packet switching and optical burst...

Design of optical packet switching networks

The technological evolution of telecommunication networks in recent years has shown that the availability of transmission bandwidth has been growing at a faster pace than the STNitChing bandwidth inside network nodes [4]. This means that in the near future electronic switching will become the perfonnance bottleneck of high-capacity networks. The cost of a Switching device (be it an IP router, a...

Design of all Optical Packet Switching Networks

Optical switches and wavelength converters are recognized as two of the most important DWDM system components in future all-optical networks. Optical switches perform the key functions of flexible routing, reconfigurable optical cross-connect (OXC), network protection and restoration, etc. in optical networks. Wavelength Converters are used to shift one incoming wavelength to another outgoing w...
