Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0020] The routing request processing method provided by this application performs routing calculation through a centralized architecture distributed computing method, and when generating resource reservation requests, priority is given to processing resource reservations corresponding to delay-sensitive requests (BR, setup-delay-bound requests) Request, while avoiding resource conflicts, improve the routing calculation efficiency of BR in large-scale networking.
[0021] In a dynamic network environment, requests can be divided into two types. One is resource conflict-sensitive requests called BR, such as large-scale configuration requests and fast service recovery requests. This type of request either wants to complete the route bui...

The present application provides a routing request processing method, the method comprising: when there is a routing request to be processed on the main computing unit, if it is determined that the routing request is a BR, then obtain TED information, perform routing calculation, and generate the BR corresponding Resource reservation request; if it is determined that the routing request is TR, then send it to the slave computing unit, so that the slave computing unit obtains TED copy information, performs routing calculation, generates a resource reservation request corresponding to the TR, and sends it to the master A computing unit; when there is a resource reservation request that needs to be processed, the resource reservation request corresponding to the BR is prioritized; when the result of processing the resource reservation request is that the resource reservation is successful, the resource reservation result is stored and a label switching path LSP is established. Based on the same inventive idea, the present application also proposes a routing request processing device, which can improve routing calculation efficiency of BRs in a large-scale network while avoiding resource conflicts.
Description
technical field [0001] The present invention relates to the field of transport network technology, in particular to a routing request processing method and device. Background technique [0002] With the continuous development of the network, the network topology is becoming more and more complex, the business volume is increasing, the network scale is increasing and tends to be more and more dynamic and automatic. In order to improve the utilization efficiency of dynamic networks, a series of network architectures using centralized controllers, such as software-defined network (SDN, softdefined network) and software-defined packet transport network (SPTN, software defined packet transport network), have begun to emerge. Their centralized control architecture supports them to build on-demand networks, meet diverse business needs, simplify the deployment of network services, and improve customer operation and maintenance experience based on this. [0003] In a large-scale net...
