A quantitative evaluation of reordering in OBS networks and its impact on TCP performance

Abstract

This paper presents a layered framework to measure the reordering introduced by contention resolution strategies in OBS networks. In particular, characterization is based on the reordering metrics proposed by the IETF IPPM WG. The obtained results are twofold. First, they quantify the impact of burst reordering on TCP throughput performance. Second, they give insight into solving burst reordering by well dimensioned buffers.
