Introduction to Seminar Topic on Wavelength Routing In Optical Networks:

The wavelength router and the end nodes are connected in a pair in an optical routing and these router and the switches are interconnected with the help of optical fiber. It is necessary that the each signal should be different although they can share same wavelength. The transmission and the receiving of the signal are done on the same wavelength. In the world all the router carry data from one point to another point.

Categories of routers: – Basically there are three types of router and they are non re-configurable router, they transfer the signal over the fixed wavelength. Once this type of router is built they cannot be changed. Another is wavelength independent re-configurable router in this type we can dynamically configure the input and output of the signal. They have fixed ports for outgoing signal and only on those ports it can receive the incoming signal. And the last one is wavelength selective re-configurable  they are the combination of above two routes. They have the property of both dynamically routing and fixed pattern routing.

Routing algorithms:- There are various type of algorithms of wavelength routing and some so them are  permutation routing problem which introduces the concept of wide sense non blocking criterion in which the at any time in the network will never going to be blocked by any problem. A wavelength for the transfer of signal is chosen from the subset of the wavelength.

In this the bounds are given according to the router needed. Another is lower bound in this the rate to increase it decided by just counting the number of links in the network. It has been assumed that without the connectors of the wavelength the signal share the same wavelength as long as no new link came in between them.
