Dynamic and static combination scheme with initial dynamic tunnel and static tunnel permanent storage recovery mechanism as core

Abstract

The invention belongs to the technical field of storage recovery mechanisms, and discloses a dynamic and static combination scheme with an initial dynamic tunnel and static tunnel permanent storage recovery mechanism as a core. The scheme has the advantages that the configured path and protection in the traditional PTN equipment deployment scheme are absolutely reliable, and the intelligent deployment and intelligent protection in the SDN controller deployment scheme are realized. The defects that a traditional PTN scheme is insufficient in intelligence and flexibility and an SDN controller scheme is low in configuration efficiency and insufficient in stability are completely overcome, and a more efficient and stable scheme is provided for deployment of the PTN.

Description

technical field [0001] The invention relates to a dynamic and static combination scheme with an initial dynamic tunnel and a permanent storage recovery mechanism of a static tunnel as the core, and belongs to the technical field of storage recovery mechanisms. Background technique [0002] When traditional PTN equipment deploys services, it is necessary to manually plan network paths based on the user's service transmission requirements and the current actual network topology, and then manually configure end-to-end services in the network through scripts or network management configuration. After that, all the configurations are saved in the device, and the configuration can be quickly restored after the device is powered off and restarted. At the same time, in order to ensure the stability of the service, the configuration of the service is generally combined with the configuration of multiple protections such as LSP tunnel 1+1 / 1:1 and ring network protection, and these pro...

Problems solved by technology

[0005] However, although the SDN controller improves the intelligent deployment of the network, there are also related limitations in practical applications.

One is because the SDN controller completely controls and saves the configuration information of the entire network. Although the SDN controller will do backup, if all the SDN controllers fail, all the service configurations will be lost, and the switching equipment will also be in an idle state at this time. The state of human control; one is that when the switching device needs to restore the service configuration due to needs, misoperation or other reasons, the configuration must be delivered through the controller. During the configuration delivery process, the channel of the service configuration is required to be as stable and smooth as possible , otherwise it will bring various retransmission operations, and the state and stability of the main SDN controller are also required during the restoration process. The duration and robustness are much worse than traditional PTN equipment
