We aim to provide a hard QoS guaranteed service with end-to-end behavior across domains in Diff-Serv. We add the bandwidth reservation process for each EF session in Diff-Serv with strict QoS provision. For this purpose, we utilize three mechanisms for the new framework: (1) local centralized resource management, (2) centralized route discovery, and (3) a sender-initiated signaling protocol. The performance of the proposed framework is evaluated against the current Diff-Serv framework and is shown to have advantages in terms of the congestion probability and average delay for both short-term and long-term EF traffic
