METHODS, CONTROLLER MANAGER AND CONTROLLER AGENT FOR ENABLING A CONNECTION BETWEEN A SWITCH OF A COMMUNICATION NETWORK AND A SWITCH CONTROLLER

摘要

A controller manager, a controller agent and methods therein, for enabling a connection between a switch of a communication network and a switch controller that performs logic switch operations. The controller manager obtains from the controller agent, measurements related to connectivity to a set of switch controllers. The controller manager then selects at least one switch controller in the set of switch controllers based on the obtained measurements, to control said switch, and instructs the controller agent to set up or route a connection between the switch and the selected at least one switch controller.
