Survivable WDM mesh networks

by S. Ramamurthy, Laxman Sahasrabuddhe, Biswanath Mukherjee - Journal of Lightwave Technology , 1999
"... Abstract—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 op ..."

Traffic grooming in an optical WDM mesh network

by Keyao Zhu, Biswanath Mukherjee - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 2002
"... In wavelength-division multiplexing (WDM) optical networks, the bandwidth request of a traffic stream can be much lower than the capacity of a lightpath. Efficiently grooming low-speed connections onto high-capacity lightpaths will improve the network throughput and reduce the network cost. In WDM/S ..."

Simulations for WDM Mesh Networks with Visual Basic

by Stefanos Mylonakis, Member Ieee
"... Abstract-Fully optical fiber networks that transmit large quantities of information due to multiple applications or because they serve large urban areas (big and small local telephone exchanges), need to be maintained fault-free at all times of their operation. The protection and restoration strateg ..."
Abstract - Add to MetaCart
strategies are critical. In this paper the modeling method and simulation tool are described that have been used for the analysis of the WDM mesh networks, their protection and their restoration when a fault occurs. The network is modeled by Microsoft Visual Basic. So this paper emphasizes the simulation

IP-Subnet Aware Routing in WDM Mesh Networks

by Swarup Acharya, Bhawna Gupta, Pankaj Risbood, Anurag Srivastava , 2003
"... We explore the problem of routing bandwidth guaranteed paths in wavelength-routed, WDM optical mesh networks. A WDM mesh network offers great flexibility in dynamically re-configuring the optical core to match the IP layer demands. In this paper, we argue that IP subnets can limit the reconfigurabil ..."

Algorithms for multicast traffic grooming in wdm mesh networks

by Ahmed E. Kamal - Communications Magazine, IEEE
"... Several of the new applications in high-performance networks are of the multicast traffic type. Since such networks employ an optical network infrastructure, and since most of these applications require subwavelength bandwidth, several streams are usually groomed on the same wavelength. This paper p ..."
Abstract - Cited by 8 (4 self) - Add to MetaCart
presents an account of recent advances in the design of optical networks for multicast traffic grooming in WDM mesh networks. The paper addresses network design and session provisioning under both static and dynamic multicast traffic. Under static traffic conditions, the objective is to accommodate a given

On partial protection in groomed optical WDM mesh networks

by Jing Fang, Mahesh Sivakumar, Arun K. Somani, Krishna M. Sivalingam - in Proc. IEEE Int. Conf. Dependable Systems and Networks
"... In this paper, we consider the problem of survivable net-work design in traffic groomed optical WDM mesh networks with sub-wavelength capacity connections. In typical sur-vivable network designs, individual sessions are provided either full protection or no protection. We consider a quality of prote ..."

Performance Comparison of Protection Strategies in WDM Mesh Networks

by Hemant K. Singh, Shreya Aggarwal, Satendra Singh, Baibaswata Mohapatra, Rajendra K. Nagaria, Sudarshan Tiwari , 2010
"... 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. Protection is one of the key techniques, which is used in designing survivable WDM networks. ..."
Abstract - Add to MetaCart
. In this paper we compare dedicated and shared protection strategies employed in WDM mesh networks to protect optical networks failure, particularly fiber failure. Dijkstra’s shortest path algorithm is considered for carrying out simulations. The paper compares the performance of protection schemes, such as
