Abstract

One of the most important characteristics of optical fibres is their huge banwidth capacity. Theoretically, Optical fibers can support a combined bit rate into the range of terabits per second, causing optical networks to be very sensistive to failures. Therefore, survivability in optical network is an imperative requirement that needs to be taken care of carefully.

There are two types of dynamic restoration technique, namely link restoration and path restoration, each of which has its merits 

and drawbacks. Although link restoration is advantageous when it comes to restoration speed and network load balancing, it requires to be preceded by a fast and efficient fault localization procedure. 

LVM Fault localization Protocol was designed to be fast and efficient. It has been shown through a simulation process that LVM protocol achieves excellent performance. We are working right now on the emulation process for LVM Protocol. The emulation process consists of an optical networks monitoring multi-layer software implementing the LVM protocol. The software presents also a GUI interface where the end user can monitor his networks. Any faulty link localized by the LVM Protocol is displayed on the GUI real-time.
