Abstract(in English) | Diffserv is a type of architecture that aims to provide QoS in the IP networks, and the AF service class in Diffserv realizes minimum bandwidth guarantee by the use of differentiated drop precedence property marked in the DSCP field on each packet. The packets comply with the guaranteed bandwidth are protected in the network by means of the differentiated forwarding behavior based on the DSCP value. In the context of multiple domains environment, however, QoS of individual flow is not always preserved due to the re-marking behavior forced at the domain boundaries. Focusing on this point, this paper proposes a new packet 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 to out-of-profile at the domain boundaries from those already marked as out-of-profile at the time of entering the network, and to give chances to the re-marked packet to recover back to in-of-profile that can enjoy its rightful QoS within the networks. Basic performance of the proposed scheme is evaluated through simulation study. Basic performance of the proposed scheme is evaluated through simulation study, and the rsults show its effectiveness in preserving QoS of the inter-domain flows. |
