Abstract(in English) | In wavelength-routing networks, an optical wavelength path is set on a route between a source node and a destination node. The note is selected by the source node. However it is difficult to decide the route at the source node with wavelength continuous constraint. it causes the blocking probability increasing. That is why there is the difference between time when requests receive at source nodes and time when LSAs (Link-State Advertisements) receive. Moreover, the interval of distributing the state of wavelengths to the others is static. In this paper, we propose the dynamic optical wavelength path establishment scheme for low-blocking probability. With the proposed scheme, an optical path is established by searching a route between source nodes and destination nodes, where a wavelength is available. When intermediate nodes on the least-hops route release wave-lengths, the node sends the message with available wavelength to the source node, which met the blocking at the last path establishment trial. The source node establishes an optical path by adopting the wavelength and the route. Without blocking wavelength reservation fail, the destination node establishes optical path to source node on the least loaded route. Our method shows lower blocking probability than existing methods. |
