摘要
The Assured Service was proposed as a possible service at IETF's Differentiated Service (DiffServ) working group. The basic idea of this service is the negotiation of a certain service profile between the ISP (Internet Service Provider) and the customer. The user tags packets leaving his end system (network) according to this profile as in- or out of profile. The ISP then forwards the in profile packets with higher priority and especially favours them in overload situations by discarding out of profile packets prior to in profile packets. One of the central questions concerning Assured Service is whether the available bandwidth is shared fairly among several flows. Some initial research in this field is done in [IN98] and [BB99]. In contrast to [IN98] especially the interaction of different kind of flows (UDP and TCP) is investigated.
