Performance analysis of a low-complexity and efficient QoS differentiation algorithm for bufferless optical packet switches with shared wavelength converters in asynchronous operation

Abstract

This paper presents a simulation study of a low-complexity optical packet switching quality of service differentiation scheme, aiming at minimising the penalty of offering packet loss rate isolation in an optical packet switch with a wavelength converter pool. Special emphasis is given to potential improvements, impact of node dimensions and overload situations.
