Abstract
After detailed analysis of four IP QoS protocols under develop (RSVP, DiffServ, MPLS and SBM), it is found that , although each protocol can support QoS service in network, none of then can be solutions to end-to-end QoS in large scale network all by itself, Only the utilization of all four procotols can realize deterministic transmission of user traffic flow in WAN. From this on, an integrated architecture for end-to-end IP QoS service is given.
