摘要
Implementing QoS, one of the eternal research subjects, on Internet has been attracting a lot of attentions although several schemes are already available. This letter proposes a new service architecture-Scalable Tri-tier Service Architecture (STSA) and a fast label switching scheme, which can reduce the overhead of signaling and suit the applications of access demand for a great number of end users with QoS guarantee. Also presented in the letter is an implementation of STSA in MPLS scenario.
