Significant Impact of P-cycles on Survivable WDM Optical Network
نویسندگان
چکیده
It is known that Wavelength division multiplexing (WDM) technique enables single fiber to carry huge amount of data but optical WDM networks are prone to failures, therefore survivability is a very important requirement in the design of optical networks. In this paper, a comprehensive review about survivability of WDM networks has been discussed focusing on scalable and efficient p-cycles resilience techniques and a comparative analysis particularly among ring and mesh resilience techniques has been performed. In the context of network survivability, p-cycle based schemes attracted extensive research interests as they maintain balance between recovery speed and capacity efficiency. It is observed that pcycles are key to obtain mesh-like network efficiency from a ring-like protection.

متن کاملGA-Based Hybrid Algorithm for MBR Problem of FIPP p-Cycles for Node Failure on Survivable WDM Networks
In this paper, the minimal backup reprovisioning (MBR) problem is studied, in which, the failure-independent path protecting pcycles (FIPP p-cycles) scheme is considered for single node-failure on WDM networks. After recovering the affected lightpaths from a node failure, the goal of the MBR is to re-arrange the protecting and available resources such that working paths can be protected against...
متن کاملA novel dynamic survivable routing in WDM optical networks with/without sparse wavelength conversion
In this paper, we study the dynamic survivable routing problem, both in optical networks without wavelength conversion and in optical networks with sparse wavelength conversion, and propose a novel hybrid algorithm for it based on the combination of mobile agents technique and genetic algorithms (GA). By keeping a suitable number of mobile agents in the network to cooperatively explore the netw...
متن کاملCycle Covering
This paper considers the design of a survivable WDM network based on covering the initial network with sub-networks, which are protected independently from each other. We focus on the case where the optical WDM network is a ring, there are requests between any pair of vertices and the covering is done with small cycles. This problem can be modelled as follows: Find a covering of the edges of a ...
متن کاملSchool of Computer Science Literature Review and Survey (0360-510, Fall 2006) Heuristics for Traffic Grooming in WDM Optical Networks with Shared Path Protection
The emergence of wavelength division multiplexing (WDM) technology has significantly increased the transmission capacity of a link in today's optical networks. In WDM networks, the bandwidth request of a traffic stream is usually much lower than the capacity of a wavelength. Traffic grooming can aggregate low-rate connections onto high-capacity optical fibers to make an efficient use of the ban...
