Protection in Elastic Optical Networks against up to Two Failures Based FIPP p-Cycle

Optical networks are subject to faults in links and nodes which can cause massive data loss. In the literature, many techniques have been proposed to deal with such failures in order to support continuous network operation. One of these techniques defines p-Cycles which provide ring-type protection and the speed of restoration of meshes. Morever, Flex grid networks emerged as a solution to deal with the diverse requirements of bandwidth. This paper presents two new algorithms to provide path protection using p-cycle path networks in Flex grid networks. Our algorithms provide 100% protection against single failure as well as against two failures.
