Sub-network based Hierarchical Segment Restoration in MPLS network
نویسندگان
چکیده
In this paper, we propose a segment restoration scheme based on network partitioning to enhance the restoration performance and to manage network efficiently. The proposed restoration scheme divides a large network into several small sub-networks. Since most faults can be restored in a partitioned sub-network or AS(Autonomous System), restoration time is reduced obviously. In this paper, we compare and analyze restoration performance according to the size of sub-networks and restoration schemes. From simulation results, the proposed restoration scheme has high restoration performance compared with other restoration schemes.

Performance Analysis about the Failure Restoration Scheme Using a Multi-path in Hierarchical MPLS Networks
Various technologies about multi-path calculation for extensibility and failure restoration have been suggested as an increasing demand for QoS in MPLS networks. However, the MPLS networks have problems in extensibility for network traffic, failure restoration that waste usage of resources and much delay. Thus, we propose to H-MPLS networks recover failure in networks fast and support efficient...
متن کاملAdaptive segment path restoration (ASPR) in MPLS networks
Two important factors must be considered when selecting a restoration scheme in MPLS networks. Firstly, the restoration time, and consequentially the packet latency of the restored trafiic, has to satisfy the requirements of realtime services. Secondly, the spare capacity requirement should be costeffective. This paper proposes a novel proactive restoration scheme that is both fast-acting and r...
