Adaptive Routing in DWDM Optical Packet Switched Network

In this paper we consider a core optical packet-switched network and investigate the effectiveness of statistical multiplexing of packets on different sets of wavelength paths. A few routing algorithms are proposed and compared that make use of wavelength multiplexing at various levels, ranging from the single fiber, to a set of fibers including shortest and even longer network paths. The aim is to design adaptive routing that outperforms conventional shortest path routing by exploiting the wavelength domain.
