The Bi-Mesh Survivable Network – Fast Recovery from Node Failure in MPLS enabled Networks
نویسنده
چکیده
Today’s converged networks are increasingly based on MPLS technology. To provide reliable carrier-grade service, MPLS-based recovery procedures must be able to quickly address any link or node failure. Current standardized MPLS fast recovery mechanisms cannot cope with egress node failure. We present a dual plane core network architecture, a path naming convention and a simple recovery mechanism that together can remove that fundamental limitation. Keywords-MPLS; fast re-route; node failure; survivability.

A new efficient spare capacity allocation algorithm in self-healing MPLS mesh-based survivable networks
Network survivability gauges the ability of a network to support the committed Quality of Services (QoS) continuously in the presence of various failure scenarios. MPLS Mesh-Based network can be used to provide network survivability in case of link and node failure through predesign path protection techniques. In the Preplanned self-healing networks, we have to provision adequate spare capacity...
متن کاملA Fast Strategy to Find Solution for Survivable Multicommodity Network
This paper proposes an immediately efficient method, based on Benders Decomposition (BD), for solving the survivable capacitated network design problem. This problem involves selecting a set of arcs for building a survivable network at a minimum cost and within a satisfied flow. The system is subject to failure and capacity restriction. To solve this problem, the BD was initially proposed with ...

متن کاملHybrid FRR/p-Cycle Design for Link And Node Protection in MPLS Networks
Survivable MPLS technologies are crucial in ensuring reliable communication services. The fast reroute (FRR) mechanism has been standardized to achieve fast local repair of label switched paths (LSPs) in the event of link or node failures. We present a suite of hybrid protection schemes for MPLS networks that combine the well-known p-cycle method with FRR technology. Whereas with pure FRR backu...
متن کاملA Review on Various Fast Reroute Schemes for Traffic Protection Mechanisms in MPLS
For a perfect network it must have ability to keep all the tasks and services running even when a link or node fails. This feature of any network is usually known as network resilience. The basic working of resilient network is that it can recover from a failure by automatically diverting the traffic from the failed portion of the network to another active part of the network. This process must...
