End-to-end service management architecture and information model for MPLS VPN with dynamic SLA management

MPLS is regarded as a technology for traffic engineering and QoS in IP-network. In this paper, we focus on the management of end-to-end VPN service based on MPLS, including system architecture and information model, which are crucial for ISPs to attract more customers and orders. We designed hierarchical architecture supporting dynamic SLA management, and also defined the supporting service information model by extracting and refining related information from the IETF MIBs. Prototype system has been implemented to verify the feasibility.
