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 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)
—This paper presents a programmable multi-granular optical cross connect (MG-OXC) and network architecture deployable in multi-service and multi-provider networks. The concept of programmable MG-OXC is introduced to provide a way of utilizing multiple switching/transport granularities to efficiently support the emerging traffic demands in both core and(More)
—Dynamic, flexible and programmable network nodes will enable the key infrastructure for the Future Internet. Re-engineering of the traditional router architectures is required in order to allow hardware-and vendor-independent routing functions and to design open and cost-effective service platforms. This paper presents a modular programmable router(More)
