Abstract
The Journal of Optical Networking's (JON) feature issue, focuses on architectures, technologies, and theory for achieving high service availability in optical transport networks. The feature accepted 14 submissions for publication, these works reflect some important directions and objectives in optical networking research. These papers can be categorized under three themes, cost considerations in survivable optical networks, optimization in survivability design including resource sharing schemes, availability guarantees, and capacity efficiency, protection in IP/MPLS over WDM. J. Farkas, A. Paradisi, and C. Antal, in their paper, proposes and experimentally validates a low-cost, robust, and scalable Ethernet-over-fiber network architecture with fast recovery from both node and link failures. The paper submitted by M. Scheffel proposes an interesting sort of template or building-block approach to constructing the end-to-end topology of a service path.
