Distributed protocol for removal of loop backs and optimum allocation of p-cycles to minimize the restored path lengths

R Asthana, YN Singh - Journal of lightwave technology, 2008 - ieeexplore.ieee.org
p-Cycle-based protection is one of the most promising techniques of span protection in
optical networks because of mesh-like efficiency and ring-like speed. We have presented a …

Second phase reconfiguration of restored path for removal of loop back in p-cycle protection

R Asthana, YN Singh - IEEE Communications letters, 2007 - ieeexplore.ieee.org
P-cycles are one of the most promising techniques used for span protection in optical
networks. However when p-cycle is used to provide protection to any failed span, there may …

[PDF][PDF] Study of p-cycle based protection in optical networks and removal of its shortcomings

R Asthana - 2007 - iitk.ac.in
A lot has been discussed in the literature about the formation of the p-cycles; however, there
are various issues still to be addressed. One such issue is the length of the restored path. In …

Removal of loop back in p-cycle protection: Second phase reconfiguration

R Asthana, YN Singh - 2006 10th IEEE Singapore International …, 2006 - ieeexplore.ieee.org
P-cycles are one of the most promising techniques of span protection used in optical
