All-optical packet switching designs have evolved in the last years. However, all-optical packet forwarding functionalities are still limited. Several label assignation methods have been studied in order to efficiently use the small label space of the designs. In this paper, we present a novel scheme for label switched path protection for networks with small label spaces, such as all-optical packet...
The paper deals with traffic recovery in IP/MPLS network carrying traffic of different priority classes. Two off-line network design problems are presented employing two different recovery mechanisms - single backup path and failure-dependent backup path protection. Also, two routing strategies are studied in this paper. A network design problem with failure-dependent path protection mechanism combined...
