    摘要： There is provided a method for optimizing the configuration of an optical network which is adapted to transport optical traffic along a path from a source node to a destination node, wherein the path can be routed via any one or more of a plurality of intermediate nodes in the optical network. The method comprises the steps of receiving an operating parameter of an optical device monitored in a plurality of nodes. The received operating parameter is compared with a threshold value. An operating status of a node is determined based on the comparison of the received operating parameter with the threshold value. The determined operating status of a node is used as a routing criteria for computing a path for routing traffic through the optical network.

    摘要： In general, techniques are described for dynamically determining a logical network topology for more efficiently transporting network traffic over a physical topology based on end-to-end network traffic demands and optical transport network (OTN) characteristics of the network. The techniques may be applicable to meeting network traffic demands placed upon a multi-layer network having a base transport layer and a logical or overlay Internet Protocol (IP) layer routed on the transport layer.

    摘要： The disclosure discloses an apparatus and method for rerouting multiple traffics. The apparatus includes a path computation unit and a traffic path incorporation unit, the path computation unit forwards a received uniform route computation notification message including multiple pieces of failed traffic connection information to the traffic path incorporation unit, and also forwards a route inquiry request transmitted from the head node of the fault traffic to the traffic path incorporation unit; the traffic path incorporation unit analyzes and detects the failed traffic connection information according to traffic incorporating and route inquiry statistic algorithm, and uniformly obtains and records the recovery route information from the path computation unit; when receiving the route inquiry request forwarded by the path computation unit, the traffic path incorporation unit is further configured to search the record according to the route inquiry request, and return the found corresponding recovery route information to the head node which requests the recovery through the path computation unit. The disclosure uses a incorporating and uniform route inquiry method, the resource loss of the path computation unit is reduced, and the efficiency of link restoration is improved.
