Carrier Ethernet (for the packet layer), optical networks (for the circuit layer) and GMPLS, are dominant enablers in this scenario. Survivability and robustness will be of critical role for the accomplishment of a transport class of network.

  • A Review of Fault Management in WDM Mesh Networks: Basic Concepts and Research Challenges
    A Review of Fault Management in WDM Mesh Networks: Basic Concepts and Research Challenges Jing Zhang and Biswanath Mukherjee, University of California Abstract This article first presents a broad overview of the fault management mechanisms involved in deploying a survivable optical mesh network, employing optical cross- connects. We review various protection and restoration schemes, primary and back- up route computation methods, sharability optimization, and dynamic restoration. Then we describe different parameters that can measure the quality of service pro- vided by a WDM mesh network to upper protocol layers (e.g., IP network back- bones, ATM network backbones, leased lines, virtual private networks), such as service availability, service reliability, restoration time, and service restorability. We review these concepts, the factors that affect them, and how to improve them. In par- ticular, we present a framework for cost-effective availability-aware connection provi- sioning to provide differentiated services in WDM mesh networks. Through the framework, the more realistic scenario of multiple near-simultaneous failures can be handled. In addition, the emerging problem of protecting low-speed connections of different bandwidth granularities is also reviewed. ith the maturing of wavelength-division multi- 109 hours, Tx denotes optical transmitters, Rx denotes optical plexing (WDM) technology, one single strand receivers, and MTTR means mean time to repair. of fiber can provide tremendous bandwidth With the frequent occurrence of fiber cuts and the tremen- (potentially a few tens of terabits per second) dous traffic loss a failure may cause, network survivability WWby multiplexing many nonoverlapping wavelength channels becomes a critical concern in network design and real-time (WDM channels).

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract An optical network is a type of data communication network built with optical fibre technology. It utilizes optical fibre cables as the primary communication medium for converting data and pass- ing data as light pulses between sender and receiver nodes. The major issue in optical networking is disjoints that occur in the network. A polynomial time algorithm Wavelength Division Multip- lexing-Passive Optical Networking (WDM-PON) computes disjoints of an optical network and re- duces the count of disjoints that occur in the network by separating Optical Network Units (ONU) into several virtual point-to-point connections. The Arrayed Waveguide Grating (AWG) filter is in- cluded in WDM-PON to avoid the traffic in the network thereby increasing the bandwidth capacity. In case of a failure or disjoint Ant Colony Optimization (ACO) algorithm is used to find the opti- mized shortest path for re-routing. For enhanced security, modified Rivert Shamir Adleman (RSA) algorithm encrypts the message during communication between the nodes.
