Designing Survivable Wavelength Division Multiplexing (WDM) Mesh Networks

School 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...

Performance Analysis of Restoration Schemes in Survivable WDM Mesh Networks

Recent development in optical networking employing wavelength-division-multiplexing (WDM) fulfills the high bandwidth demand applications. Failure of such networks, leads to enormous data and revenue loss. Design a low cost survivable WDM network is always an interesting and difficult process. In this paper we present link-path model for capacity allocation and calculate blocking probability in...

Significant Impact of P-cycles on Survivable WDM Optical Network

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 resil...

Dynamic Provisioning of Survivable Multicast Sessions in Optical WDM Mesh Networks

We investigate dynamic provisioning of multicast sessions while protecting them against any single fiber cut in optical WDM mesh networks. Our proposed segment-protection and path-pair-protection schemes exhibit very good performance relative to other schemes.
