Survivable WDM Mesh Networks
In a wavelength-division-muliplexing (WDM) optical network, the failure of network elements (e.g., fiber links and cross connects) may cause the failure of several optical channels, thereby leading to large data losses. This study examines different approaches to protect a mesh-based WDM optical network from such failures. These approaches are based on two survivability paradigms: 1) path prote...
متن کاملRestorations for Small Scale WDM Mesh Networks
This paper presents a WDM (Wavelength Division Multiplex) mesh network planning and designing that satisfies given demands and a restoration approach. This restoration approach is based on the network traffic rearrangement by all source and destination nodes with the shortest path algorithm ignoring the failed link and when a link has inadequate capacity, the problem is solved by both nodes of ...
متن کاملOperating Mesh Survivable WDM Transport Networks
All optical networks with wavelength division multiplexing WDM are considered to be a promising technology for next generation transport networks as they can satisfy the growing bandwidth demand caused primarily due to an explosive growth of web related services over the Internet As the tra c demand increases survivability becomes an indispensable requirement in WDM transport networks This moti...
متن کاملWDM Loop-back Recovery in Mesh Networks
Current means of providing loop-back recovery, which is widely used in SONET, relies on fiber-based recovery, where a fiber is used to back up another fiber. We present WDM-based loop-back recovery for optical networks where wavelengths are used to back up other wavelengths. We present two new algorithms for performing WDM-based loop-back over optical mesh networks. The first algorithm performs...
متن کاملProvisioning Algorithms for WDM Optical Networks 1
This paper concerns connection provisioning for optical networks employing wavelength division multiplexing. A heuristic algorithm is developed and numerically studied for routing and wavelength assignment of a set of static connection requests. The algorithm runs much faster than the optimum solution of this problem. An adaptation of the algorithm is proposed to design restorable networks whic...
