Technologies for bridging between coarse-grained and fine-grained load balancing

One or more non-transitory machine-readable media comprising a plurality of instructions stored thereon that in response to being executed by a processor cause a computing node of a cluster computing device to:

• store a plurality of network flow entries in a local flow table of the computing node;
• store forwarding information for one or more of the plurality of network flow entries in a local next hop table of the computing node;
• receive network flow information from a network controller;
• add a network flow entry to the local flow table of the computing node based on the network flow information received from the network controller;
• generate a multicast network packet comprising the network flow information received from the network controller and an internet protocol address associated with the computing node;
• and
• transmit the multicast network packet to each other computing node of the cluster computing device to facilitate the addition of a different network flow entry to a local flow table of each other computing node and a next hop entry to a local next hop table of each other computing node based on the multicast network packet.

A method for bridging between coarse-grained and fine-grained load balancing, the method comprising:

• storing, by a computing node of a cluster computing device, a plurality of network flow entries in a local flow table of the computing node;
• storing, by the computing node, forwarding information for one or more of the plurality of network flow entries in a local next hop table of the computing node;
• receiving, by the computing node, network flow information from a network controller;
• adding, by the computing node, a network flow entry to the local flow table of the computing node based on the network flow information received from the network controller;
• generating, by the computing node, a multicast network packet comprising the network flow information received from the network controller and an internet protocol address associated with the computing node;
• and
• transmitting, by the computing node, the multicast network packet to each other computing node of the cluster computing device to facilitate the addition of a different network flow entry to a local flow table of each other computing node and a next hop entry to a local next hop table of each other computing node based on the multicast network packet.
