CONFIGURING A NETWORK PATH IN AN SDN

Abstract:

It is presented a method for configuring a network path. The method is performed in a routing control device of a software defined network and comprises the steps of: receiving a first node packet originating from a first node of the software defined network, the first node packet forming part of an ARP exchange between an ARP requester and an ARP responder, the first node packet comprising a request for network properties encoded in a first address; determining a network path through the software defined network; changing a source address of a packet to the ARP requester to be a second address; configuring all switches forming part of the network path, to route packets in accordance with the network path; and configuring an edge switch to replace, for all packets having a destination address being equal to the second address, the destination address with an address of the ARP responder.
