Optical label switched networks:laboratory trial and network emulator in the IST STOLAS project

This article reviews the performance of an optical-label-controlled packet routing node as implemented in the European FP5-IST STOLAS project including a set of general engineering rules. Experimental networking scenarios and results from a STOLAS based network emulator supporting optical overspill routing are presented

Label-controlled optical packet routing � Technologies and applications

An overview is given of various optical packet labeling techniques. The architecture and technologies are discussed for optical packet routing nodes using orthogonal labeling with optoelectronic label processing, and for nodes using time-serial labeling with all-optical time-serial label processing. An example of a near term application is given, and a comparison of routing technologies is made regarding their cost and reliability aspects

Breusegem, “Optical packet routing using orthogonal labeling

Abstract FSK/IM orthogonal labelling of data packets enables high router throughputs and hybrid circuit-/packetswitched networks. The node cascadability is limited by the required payload extinction ratio, and the speed of the label swapping wavelength converters

Optical packet routing using orthogonal labeling - results form the FP5 STOLAS Project

FSK/IM orthogonal labelling of data packets enables high router throughputs and hybrid circuit-/packet-switched networks. The node cascadability is limited by the required payload extinction ratio, and the speed of the label swapping wavelength converters

GMPLS extensions for supporting advanced optical networking technologies

In response to the need for higher flexibility in optical networks, a Generalised Multi-Protocol Label Switching (GMPLS) protocol suite is currently under standardisation. However, in these standards a Label Switched Path (LSP) hierarchy is defined that only considers circuit-switched optical networks. This paper aims at broadening the scope of this hierarchy to more advanced optical networking technologies
