Design and evaluation of a P2MP MPLS-based hierarchical service management system

This paper proposes a point-to-multipoint (P2MP) Multi-Protocol Label Switching (MPLS) based hierarchical service management system. Traditionally, general management systems deployed in some service providers control MPLS Label Switched Paths (LSPs) (e.g. RSVP-TE, LDP) and services (e.g. L2VPN, L3VPN and IP) separately. In order for the dedicated management systems for MPLS LSPs and services to cooperate with each other automatically, a hierarchical service management system has been proposed with the main focus on point-to-point (P2P) TE LSPs in MPLS path management. In the case where P2MP TE LSPs and services are deployed in MPLS networks, the dedicated management systems for P2MP TE LSPs and services must work together automatically. Therefore, this paper proposes a new automatic correlation between P2MP TE LSPs and each service. In particular, this paper proposes a new algorithm for a correlation between P2MP TE LSPs and multicast VPN services. The capacity and performance searching on both a sub-LSP and correlation tables are evaluated, and the results show this system is very scalable within real MPLS production networks. This system, with automatic correlation, appears to be deployable in real MPLS production networks.
