Priority-based routing and wavelength assignment algorithm of multi-objective in WDM network by Xiang-xuan TIAN, Jun-gang YANG, Ya-liang CHE, Wen-zheng SUN, Gu-jing LIU

“…An effective algorithm aiming at the multi-objective routing and wavelength assignment through priority in dynamic WDM optical network was proposed.The objective of the design is to maximize the number of accepted communication requests subjected to a limited number of wavelength channels.The relation between path type was adopted and the traffic volume was used to determine the priority of the connection requests,and the network state was incorporated into the routing decisions and wavelength assignment.The simulation results conclusively demonstrate that the proposed algorithm can greatly improve the blocking performance and utilization of the optical network resource.…”

Research and practice on fault location technology based on open optical transport network by Hao LIU, Xiaoli HUO, Qian HU, Yi DING

“…At present the network management system of different types of equipment are relatively independent.The problem about how to quickly recover network failure towards inter-domain optical networks is required to be solved in terms of network operation and maintenance.Some fault location schemes within inter-domain optical networks were studied.When any inter-domain fault occurs, firstly, some technologies about automatic link discovery protocol and pilot tone technology of optical modules were applied to get complete optical link information and data.Then, real-time performance monitoring technology and root cause analysis function were used to find the root alarm towards specified network fault.Ultimately the management domain of optical transport networks has been extended by using those methods above on basis of developed prototype system of transmission network operation quality analysis, which may produce an end-to-end open and unified optical transport network management system including the remote client side.…”

Mechanism for green unicast routing protection in multi-granularity transport networks by Jun-ling SHI, Xing-wei WANG, Min HUANG

“…The mechanism for green unicast routing protection is designed with the constraint of quality of service (QoS),energy consumption and the survivability of single link or node failure considered.The path is calculated under the constraint of QoS based on K-shortest path algorithm.The resource allocation is done on multi-layer auxiliary graph considering the minimum times of wavelength conversion.Three protection levels are provided according to the service demands.The mechanism is implemented over EON (Europe optical network) topology by simulation.Performance evaluation has been done on the blocking probability,the protecting/working resource ratio and the load balance degree by comparing with certain existent mechanism.It has been shown that the proposed mechanism is both feasible and effective.…”
