摘要：

This paper addresses the dynamic recovery problem in the wavelength division multiplexing mesh networks with traffic grooming capacity. We propose two restoration schemes. They are connection dynamic restoration scheme and lightpath dynamic restoration scheme. We also propose two restoration protocols, connection restoration protocol for connection dynamic restoration scheme and lightpath restoration protocol for lightpath dynamic restoration scheme, and formulate a model of restoration switching times for the two restoration schemes. Numerical result shows that connection dynamic restoration scheme and lightpath dynamic restoration scheme can achieve a better tradeoff of resource utilization rate and restoration success rate than protection scheme. Traffic grooming technology helps to improve the restoration success rate as well as to reduce restoration switching time. Connection dynamic restoration scheme yields a better performance than that of lightpath dynamic restoration scheme in terms of restoration success rate and restoration switching time. © 2014 IFSA Publishing, S.
