Architectural issues for robust optical access

Muriel Médard, Steven Lumetta

Research output: Contribution to journalArticlepeer-review


Optical access networks are beginning to be deployed at the edge of the optical backbone network to support access by the high-end users that drive increased bandwidth demands. This development in the applications of optical networking poses new challenges in the areas of medium access, topology design, and network management. In particular, since optical access networks carry high volumes of critical traffic, the level of reliability and robustness traditionally reserved for core applications must be implemented in access networks. In this article we survey access network architectures and outline the issues associated with providing reliability for these architectures.
