1 Design and Implementation of Configuration Management for the MPLS Network

MPLS has been developed to manage the massive high-speed Internet traffic efficiently. The major advantages of the MPLS are fast label switching mechanism to increase the packet forwarding capability, and connection oriented traffic engineering to provide flexible load balancing in the transit network. The MPLS can provide efficient transit networking based on the connection-oriented LSP to support the QoS of VPN (Virtual Private Network). It can also support the differentiated service provisioning with DiffServ-aware-MPLS structure. For efficient network management, it is essential to gather the information of the exact network topology and resource; but it is difficult to manually discover the network topology of a large scale network with the legacy network management system. In this paper, we propose a Configuration Management system for MPLS network with auto-discovery of physical network topology and MPLS LSP virtual topology. The proposed configuration management system also provides the MPLS-VPN configuration and provisioning function. For the efficient management of the large traffic volume at high speed Internet, MPLS has been developed to support the effective traffic engineerin
