A Review of Network Survivability in Optical Networks
Neeraj MohanGauravpreet Singh
摘要：The survivability of optical networks is very important issue to address. It is critical because of the fact that these networks are high speed networks and they can handle a large volume of data. Link failures or path failures are very common in optical networks. These failures may cause a huge loss in term of data, time and revenue. To minimize this loss the failed network need to be restored as early as possible. The effect of failure may be minimized if the link is restored to reroute the affected traffic accurately and quickly using the available network resources. The different survivability mechanisms are used as per the need and nature of the network. The main focus is to handle the single link failures and multiple link failures. Multiple link failures may contribute toward the path failure. We have critically reviewed the existing network survivability schemes. Most of these schemes are either network protection schemes or network restoration schemes.
