A switching node architecture for multi-rate path establishment in multi-wavelength label switching networks

摘要

We propose a mechanism of establishing multi-rate lightpaths in a multi-wavelength label network, which was proposed by the authors. In this mechanism, a source node sends optical packets in the interval assigned by the network. To establish more lightpaths, we then propose a switching node architecture that has buffering capability by using fiber delay lines. We show the effectiveness of this mechanism by comparing it with that of a WDM network and that of a multi-wavelength label network without the fiber delay lines.
