ORBIS: A Reconfigurable Hybrid Optical Metropolitan Area Network Architecture

Abstract

Abstract. In this paper, we propose a novel metropolitan area network (MAN) ring architecture, ORBIS, a multiple-service WDM platform that supports multiple transport techniques. The WDM ring is horizontally divided into multiple subnetworks, each of which supportsonetype of the traffi.c with a subset ofthe total wavelengths. The system and subnetwork control mechanism and reconfiguration issues are addressed in this paper.
