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.

Abstract: Techniques for multi-path routing of packets to a destination node based on multiple routing tables of a router device. In an embodiment, a router device includes port groups which each correspond to a different respective network path to the same destination node. In another embodiment, each routing engine of multiple routing engines in a router device routes packets to the destination node based on a different respective one of multiple routing tables. The routing tables may include respective entry sets which, at least with respect to routing packets to the destination node, dedicate each routing engine to a respective one of the port groups.
