Abstract: This paper proposes an ingrative scheme of differentiated service (DiffServ) for the Internet. In this scheme, the quality of service (QoS) is ranked according to the levels of both importance and urgency, which makes the service negotiation and the implementation mechanism more flexible and universal. Samples of implementation mechanism at the edge nodes and interior nodes are described, and stochastic Petri net models of them are given. Performance of the Per-Hop-Behavior (PHB) implementation mechanism is analyzed, under both Poisson and self-similar arrivals. An approximate analysis technique of decomposition and iteration is used to reduce complexity. For self-similar traffic, an MMPP-based self-similar model is used.
