A Design of Platform for QoS-Guaranteed Multimedia Services Provisioning on IP-Based Convergence Network

摘要

In order to provide QoS-guaranteed real-time multimedia services, establishment of QoS-guaranteed per-class-type end-to-end session and connection is essential. Although the many researches for QoS-guarantee have been applying to the provider's network, these have not been completely guaranteeing the end-to-end QoS yet. The topic of the end-to-end QoS-guarantee is still an open issue. In this paper, we propose a platform supporting real-time multimedia services of a higher quality between end-users. To guarantee the QoS between end-users, we use the SDP/SIP, RSVP-TE and CAC. The SDP/SIP establishes end-to-end sessions that guarantee the users' demanded QoS. The RSVP-TE and CAC establish the QoS-guaranteed path between edge nodes on network for the established session through SDP/SIP. The proposed platform can apply to not only the existing IP-based network but also the wired/wireless convergence network of near future.
