Networking systems with dynamically changing topologies

摘要

Network performance may be improved by adjusting a logical network topology while avoiding attendant disruptions. By identifying an alternative logical topology, routing network traffic away from links that will be eliminated from the alternative logical topology, and updating a traffic routing plan upon the adoption of the alternative logical topology, a network may adopt a more efficient topology without misdirecting network traffic.

主权项

1. A computer-implemented method to, in response to a network event, reconfigure a network topology of a network having a configurable patch panel and a software-configured packet switch, comprising:
identifying, by a solver, an alternative logical topology different from a current logical topology; identifying, by the solver, a link in the current logical topology not present in the alternative logical topology, and generating a temporary traffic routing plan bypassing the identified link; reconfiguring, by a patch panel manager, the configurable patch panel to implement the alternative logical topology; and providing, by a network element manager, the temporary traffic routing plan to the software-configured packet switch for implementation prior to the reconfiguring, and an updated traffic routing plan based on the alternative logical topology to the software-configured packet switch for implementation after the reconfiguring.
