The method includes the following steps performed by a processing chain upon detection of a stream at a given wavelength by a given input port: determining a resource of the node based on a predetermined routing policy such that, for a given wavelength common to source and destination nodes of the stream, routing within the network is carried out according to a routing tree covering the network, a root of the tree being the destination node; consulting an occupancy table for the resource, indicating if at least one possible preceding stream is using the resource; determining a delay to be applied by the processing chain to prevent a collision between the stream and the possible preceding stream; and configuring the processing chain to apply the delay.

摘要： An optical routing scheme in which an optical network having a mesh topology is configured to route optical packets through an optical routing layout superimposable with the mesh topology, but having a star-like topology. Using this routing layout, the optical network can be configured to transport optical packets from respective ingress nodes, through the hub node located at the star center, to respective egress nodes in a manner that enables a data throughput that approaches the theoretical capacity. No special hardware is required for implementing the hub functionality, and any node of the optical network can be configured to serve as the hub node. The latter feature enables relatively straightforward optimization of the optical routing layout and transmission schedule, e.g., by changing the identity of the hub node and adjusting the transmission schedule at the ingress nodes to synchronize packet arrivals to the hub node.
