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...

Abstract

The application provides a routing request processing method. The method comprises the following steps: when a routing request needing to be processed is existent on a main computing unit, acquiring TED information when determining that the routing request is a BR, and performing the routing computing to generate a resource reservation request corresponding to the BR; if determining that the routing request is a TR, sending to a slave computing unit, enabling the slave computing unit to acquire TED transcript information, performing the routing computing to generate a resource reservation request corresponding to the TR, and sending to the main computing unit; preferentially processing the resource reservation request corresponding to the BR when the resource reservation request needing to be processed is existent; storing a resource reservation result and establishing a label switched path LSP when the result of processing the resource reservation request is that the resource reservation is successful. Based on the same invention conception, the application further provides a routing request processing device, and the routing computing efficiency of the BR in the large-scale networking is improved while the resource conflict is avoided.

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...
