Abstract

A Postponement strategy for short lightpath teardown in wavelength-routed WDM mesh networks under dynamic traffic is proposed for the first time. This strategy postpones the teardown process of the short lightpaths when there is no traffic on them. In this way, the average hop number of lightpaths will be reduced and thus more lightpaths may be set up to reduce the overall blocking probability. Moreover, since the proposed strategy extends the average holding time of lightpaths, it can help reduce the signaling flow in the optical control plane. Continuous-time system (CTS) simulation shows that the strategy is capable of reducing the overall blocking probability and the signaling flow in the optical control plane.
