Simpler control plane: Deploying LDP/RSVP-TE is not required. Instead, only IGP/BGP extensions need to be used to implement label distribution or synchronization for devices. Alternatively, a controller is used to uniformly distribute SR labels and deliver or synchronize them to devices. ...
The link currently in use is periodically compared with the optimal link for path selection and optimization, implementing intelligent traffic steering. In addition, one core controller is deployed to perform centralized O&M on the entire financial network and implement E2E management and scheduling....
