Optical Network Accurate Performance Monitoring Placement Algorithm
2015/5/15
We propose a novel monitor placement algorithm that reduces significantly the number of monitors required to accurately assess the QoT of all lightpaths established in an optical network, compared to ...
Adaptive Self-Reconfigurable Network to Create Cost-Effective Bandwidth-On-Demand Services
Networks assignment routing algorithms
2015/6/5
We propose a novel path-provisioning algorithm that can cost-effectively create bandwidth-on-demand services. Its use of the ‘make before break’ rerouting technique reduces blocking probability while ...
