This paper presents an overview of various existing network survivability techniques implemented in optical WDM networks and proposes an efficient network survivability approach. The proposed approach works on the principle of preplanned protection which adopts dynamic restoration strategy to improve the wavelength usages and call connection rate under(More)
Packet contention is a key issue in optical packet switch (OPS) networks and finds a viable solution by including optical buffering techniques incorporating fiber delay lines (FDLs) in the switch architecture. The present paper proposes a novel switch architecture for packet contention resolution in synchronous OPS network employing the packet circulation(More)
