Abstract

Making end-systems accountable for the congestion they cause will give an incentive to control one?s congestion appropriate. re-ECis a new Transmission Control Protocol (TCP) mechanism to expose the expected congestion on a network path. Based on such an announcement, the amount of congestion one end-system is allowed to introduce into the network can be limited. In the re-ECN framework a policer at network ingress is proposed which drops packets in congestion situations, if no so-called congestion credits are available. However, this will only allow to limit congestion of upstream traffic. If data is requested by a client, the server will not be able to decide about an appropriate data handling as the intention of the client is not known. To address this problem an architecture to transfer congestion credits from the client-side policer to the server-side policer could be used. This paper suggests and discusses solutions for such an accounting system.
