A Cut-off priority flo classification policy for data-driven IP/ATM switching systems

摘要

Flow classification is one of the key issues in the desing of a data-driven IP/ATM switching system. To classify flows by applications is an effective approach in a real system due to its simplicity in implementation. In this paper, we propose a cut-off priority flow classification policy to improve the application-based flow classification policy. The basic idea is to assign priorities to the applications that are selected for ATM switching so that those comparatively longer-lived applications may have better performance under heavy traffic load. Performance analysis is also carried out to show the efficiency of this cut-off priority flow classification policy.
