Survivability in Transparent Optical Networks

In optical networks, an event of failure causes a huge amount of data loss and interrupts a great number of connections, because several channels are multiplexed in only one optical fiber. In this context, survivability is essential in the project and in the operation of optical networks. Survivability is the capacity of the network do not interrupt the active connections in the presence of a failure. In this area, we analyzed the performance of the survivability mechanisms of transparent optical networks. A novel mechanism is proposed envisaging a network more flexible and, consequently, more suitable to the user.
