Abstract: This paper presents two new off-line Traffic Engineering methods for multiservice backbone networks capable of surviving against single or multiple node and/or link failure(s). In multi-service backbone networks, traffic with different Quality of service (QoS) requirements together with Best-Effort (BE) traffic without QoS requirements inhere. Both methods provide the primary and where required the backup routes for the QoS-guaranteed flows and the routes for the BE flows. The one method is based on a novel Linear Programming (LP) TE optimisation problem while the other method involves a heuristic TE algorithm, which is based on Graph Theory. Test results regarding the two offline TE methods are presented.
