| Abstract(in English) | Diffserv is a type of architecture that aims to provide QoS in the Internet, and by using AF service class in Diffserv, we can provide minimum bandwidth guarantee. In the context of multiple domains environment, QoS of individual flow is not always preserved due to the DSCP re-marking behavior forced at the domain boundaries. Focusing on this point, this paper proposes a new DSCP re-marking scheme that can improve per-flow QoS of AF service traversing multiple domains of Diffserv networks. The basic concept of the scheme is to distinguish packets re-marked at domain boundaries from packets retaining the DSCP at the user-network interface. We evaluated the performance of the proposed scheme with TCP flows through simulation study, and the results show its effectiveness in preserving QoS of the inter-domain TCP flows. |
