Abstract

All-optical networks are able to transport data from source to destination entirely in the optical domain. This is a departure from current optical networks that rely on optical-electrical-optical (OEO) conversion at each intermediate connection node to route data properly. The opacity inherent in traditional networks is costly in terms of limiting bandwidth and increasing switching complexity. MPLS, OBS and OPS have been proposed as solutions for realizing an all-optical network. MPLS and OBS have the advantages of creating all-optical connections between nodes, but do not allow intermediate nodes to use the wavelength as well. Additionally, optical switches are constantly being reconfigured to accommodate new connections. OPS can make switching decisions in the optical domain, but the technology is immature. Light trail technology tries to avoid the pitfalls of immature technology, the inability of intermediate nodes to use a connection wavelength, and the constant reconfiguration of switches. A light trail is a unidirectional optical bus between nodes that allows intermediate nodes to access the bus. The goal is to minimize the amount of active switching that needs to be done by allowing intermediate nodes to use a connection that has already been setup. Connections are not constantly being setup and torn down, but rather exist for as long as they are being used by any of the nodes along their light trail.
