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 (106), a controller agent (108) and methods therein, for enabling a connection between a switch (102) of a communication network and a switch controller (104A) that performs logic switch operations. The controller manager obtains (2:2) from the controller agent (108), measurements related to connectivity to a set of switch controllers (104). The controller manager then selects (2:4) at least one switch controller (104A) in the set of switch controllers based on the obtained measurements, to control said switch, and instructs (2:5) the controller agent (108) to set up or route a connection between the switch and the selected at least one switch controller (104A).
