Method and device for automatically distributing and managing three-layer VPN service resources

Abstract

The invention discloses a three-layer VPN service resource automatic allocation and management method and device; the method comprises the steps: building various resource pools for automatic allocation, planning an available resource range, and setting a resource occupation state to be idle; when the resources are automatically distributed, carrying out resource pre-occupation according to different networking models: port resources are firstly distributed, and then distributing the soft resources sequentially; when the soft resource is allocated, if the service is newly opened, allocating a new resource in the corresponding resource pool; if yes, inquiring existing VPN service resource information in the current network, and sequentially allocating port resources and soft resources; after the resources are successfully distributed, varying the resource occupation state into a pre-occupation state, and updating and monitoring the resource occupation state. According to the method and the device, automatic distribution and dynamic management of the three-layer MPLS VPN service resources are realized, and refined management and control of the VPN service resources are realized.

Description

technical field [0001] The invention relates to the field of three-layer VPN service activation, in particular to a method and device for automatically allocating and managing three-layer VPN service resources. Background technique [0002] The resources involved in the provisioning of Layer 3 VPN services mainly include: PE equipment, physical ports, logical ports, VRF, RD, and ImportRT / ExportRT. Corresponding resources need to be allocated according to service access requirements and operator service specifications. Due to different VPN networking models and service access requirements, there are differences in allocation rules, and the allocation process is relatively complicated. If allocation errors or conflicts will affect the normal use of services, at present, the industry mainly uses manual maintenance ledgers (manual maintenance of resource lists and manual maintenance) allocation of resources). [0003] In the actual network, the resources used by the business of...
