Fault Restoration Techniques for MPLS with QoS Constraints
نویسندگان
چکیده
This paper investigates distributed fault restoration protocols for multiprotocol label switching (MPLS) that automatically reroute label switched paths in the event of failures while maintaining quality of service (QoS) requirements. Protocols for link restoration, partial path restoration, and path restoration are evaluated. A new adaptive approach to selecting backup routes is proposed to maximize the probability of successful restoration and minimize restoration time. A route selection algorithm based on optimization of equivalent bandwidth is presented and demonstrated for an example network.

متن کاملObject-Oriented Design and Implementation of Fault Management Function for MPLS network
In this paper, we propose a fault management with fast rerouting restoration scheme in MPLS network. The proposed scheme finds out the root cause of the occurred fault, and provides differentiated service with guaranteed QoS (Quality of Service) according to the differentiated backup path options. It can provide various backup path options, such as 1:1, 1:N or M:N fast-reroute by NMS, and opera...
