Introduction to Dual Link Failure Resiliency through Backup Path Mutual Exclusion Project:

The main objective of this paper is to give idea of dual link failures. As usage of networks are increasing are day to day, we expect high transmission speed without any interruption. At present huge amount of information is being transferred in the networks and it is necessary to avoid any interruption due to failures.

The main reason why interruption occurs is due to dual link failures. These are important to solve because the links share resources, if there is any failure in shared resources this results in the failure of multiple links and the repair time for a failed link may be few hours or days and this is sufficient  for a second failure to occur. These dual link failures can be reduced by giving automatic backup path. By using this we can avoid dual link failures. This requires a hard disk of 40gb capacity, Ram of minimum 256mb,Processor with speed 3.0ghz and software’s like JDK, Java Swing and Sql 2000.

Brief into design and working:

The networks can be protected from link failures by path protection or link protection. By using path protection we can restore connection end to end by giving a backup path, back up path is given such that if the original path fails to work then this backup path comes into action.

Link protection is used to recover the signal by re-routing the connection at the place where the link is failed. When link protection is done to two failed links independently, then if they fail simultaneously these two links will not use each other in backup paths. This is called Backup link mutual exclusion.
