Keywords: Optical packet switching Wavelength conversion Shared-per-wavelength optical architecture Markov chains Fixed-point analysis a b s t r a c t This paper compares four different architectures for sharing wavelength converters in asynchronous optical packet switches with variable-length packets. The first two architec-tures are the well-known(More)
— This paper describes a multistage switch based on the broadcast-and-select principle. It implements shared per node wavelength conversion for contention resolution in optical packet-switched networks. A novel scheduling algorithm is proposed to control packet forwarding in synchronous context. An analytical model is provided to calculate the packet loss(More)
— This paper describes the scheduling algorithms to control the optical packet forwarding in a multi-stage switch based on the broadcast-and-select principle. The aim of control algorithms is to fully exploit switch resources while avoiding contention in the wavelength and space domains. A multi-stage switch based on the shared per node wavelength(More)
