Abstract

In a software defined network, dataplane connectivity is established between a computing device in the network and a controller. The computing device receives a probe packet from the controller, and identifies a port of the computing device through which the probe packet was received. The computing device sets a local route for communication with the controller through the identified port. The computing device then establishes a connection with the controller through the local route. This procedure is reiterated to incrementally expand network connectivity to a plurality of network devices.
