Multicast Routing Techniques to Make Optical Network Survivable Against Single Link/Node Failure
Link/node failures are very common in any networks but these failures have a huge impact on the overall performance of the network. Due to these link/node failures sometimes it is impossible to communicate in b/w the network or to send or receive data from sender to receiver. So to overcome such problems researchers created few techniques which can tackle with these problems and can overcome them. In this paper those techniques are reviewed. These algorithms are used for protection of both single-link and single link/node failure scenarios.
