An adaptive bandwidth scheduling for throughput and delay differentiation

Abstract

In the article, we proposed a new scheduling architecture based on rate-proportional servers, which is able to support different services in the DiffServ model by using a single service discipline. The scheduling algorithms allow to reduce the implementation complexity at the network node in the sense that there is no need to deploy a multi-level scheduling architecture for multiple types of services and for link sharing. The network operator is able to provide not only delay differentiation but also other services, such as bandwidth reservation, link-sharing or traffic engineering, etc.
