Abstract
The Internet is becoming an important communication infrastructure of the society, and thus it is no longer sufficient to simply be able to provide connections: a higher quality of service (QoS) in communications is increasingly being required. As a new framework for providing QoS services, DiffServ is undergoing a speedy standardization process at the IETF. DiffServ not only can offer tiered levels of services, but can also provide guaranteed QoS to a certain extent. In this paper, we examine a single DiffServ node model which utilizes a token bucket as the policing mechanism, and propose a way of configuring various control parameters in order to accommodate various UDP/TCP traffic. Then, through simulation, we evaluate the throughput characteristics in various cases where TCP and UDP are mixed or separated in different queues, and study the appropriateness of the configurations. The results indicate that the throughputs can be maintained as specified in the Service Level Agreements (SLA) over a considerably wide range of bucket sizes and discard thresholds in the QoS control mechanism.
