Multi-Failure Post-Fault Restoration in Multidomain DWDM Networks
Multi-Failure Post-Fault Restoration Multidomain DWDM Networks
2011/5/25
This paper proposes an adapted crankback-enabled post-fault restoration scheme against large-area failure events in multi-domain DWDM optical network. This novel solution provides recovery and resourc...
On Multiplexing Optimization in DWDM Networks
Fiber optics optical communications Networks network optimization
2011/5/25
We propose a novel graph model for multiplexing optimization in optical networks and evaluate the performance of several multiplexing policies. Simulation shows that our advocated multiplexing policy ...
Efficient Routing in Heterogeneous Core DWDM Networks
Networks assignment routing algorithms network optimizatio
2010/6/5
We design a cost efficient routing algorithm and prototype a network planning tool to cost-effectively provision high-speed connections over a large carrier’s heterogeneous core DWDM network with mult...
Weight-based Algorithm for Demand Aggregation in SONET/DWDM Networks
Algorithm Demand Aggregation SONET/DWDM Networks
2009/7/17
A weight-based heuristic algorithm was developed to efficiently aggregate UPSR demands into SONET rings over DWDM networks in order to minimize the total number of optical line cards for a given set o...
Suppression of XPM Penalty in Dispersion Managed Hybrid 10G/40G/100G DWDM Networks Using Group Delay Management
XPM Penalty Dispersion Managed Hybrid DWDM Networks Group Delay Management
2009/7/17
We propose a novel group delay management technique which effectively suppresses XPM accumulation in hybrid 10G/40G/100G DWDM networks. Systematic investigation reveals its high effectiveness for vari...
