Resource allocation for contention-resolution strategies in OPS

Abstract

All-Optical Networks are believed to be the basis of the Next Generation Internet (NGI) infrastructure. Contention resolution represents a challenge considered when implementing resource allocation. This paper presents a performance evaluation for Optical Packet Switching (OPS), attempting to solve contention resolution applying resource allocation through two strategies: Minimum packet buffering (minBuff) and minimum conversions (minConv). We consider an OPS architecture with a shared converter pool and output buffers. It is shown that for a given dimensioning, an appropriate strategy may optimize the performance of the system in terms of Packet loss probability.
