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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
