networks have recently been proposed to realize fast
restoration from a network failure. With increasingly
diverse QOS(Quality of Service) requirements, it is
practical to perform prioritized restoration. In this
thesis, prioritized pre-assigned backup VP(Virtual Path)
restoration algorithm is proposed. A novel bi-directional
restoration concept is proposed to shorten restoration
time. Time to detect a failure of pre-assigned backup VP
restoration is reduced via this approach. Another fallback
restoration algorithm can be applied subsequently.
Restoration performance is analyzed via computer
simulation. Moreover, to improve pre-assigned restoration
performance, simple routing schemes are proposed and
discussed.
