Abstract

In order to provide QoS-guaranteed realtime multimedia services on IP-based transport network, tightly coupled interactions of session & connection management and CAC (connection admission control) is essential. Also, for efficient QoS-guaranteed DiffServ provisioning across multiple AS domain networks, a scalable transit networking scheme must be provided so as to configure per-class-type QoS-guaranteed packet processing and to provide scalable connection admission control (CAC). In this paper, we propose a functional architecture of session & connection management with SIP, RSVP-TE, CAC and QoS-guaranteed virtual networking. We also propose a per-class-type virtual networking scheme for scalable QoS-guaranteed DiffServ provisioning across multiple autonomous system (AS) domain networks. The implementations of the proposed distributed session & connection management functions are based on Web Service architecture and XML/SOAP-based network management.
