SALCEDO, Octavio; LOPEZ, Danilo  e  PEDRAZA, Luis F. Time failover evaluation on GMPLS LSPL1VPN networks. Tecnura [online]. 2012, vol.16, n.34, pp.56-66. ISSN 0123-921X.

Nowadays network failure is a common problem that is caused, to certain extent, by various factors such as the number of devices involved in a link, the quality of these devices, their geographical location, and environmental conditions among others. There is a great deal of factors influencing network failure occurrence, which indicates that, whether expected or not, failure will always be present. However, the issue is not about having or avoiding failure but about how quickly can a network recover and restore its services. The present paper addresses the point of failure-recovery time of an L1VPN over GMPLS technology, where failure can be automatically overcome through routing protocols by redirecting packets to alternate routes.
