Abstract

In wavelength-routed networks, the scarcity of wavelength-converters severely impacts successful connection recovery. This can be mitigated by releasing the connection’s stubs (i.e. the surviving upstream and downstream span and node resources) prior to the restoration process. Releasing span resources however heavily complicates the reversion process. In this study, we present a nodal stub-release method, where only node resources (i.e. wavelength-converters) are released, while the stubs’ span resources are kept occupied. Our simulation results show that the nodal stub-release method can match the performance of full stub-release (releasing both span and node resources) while keeping complexity low.
