Abstract: In general, the subject matter of this disclosure relates to a system for optimally balanced network multipathing. An example system includes a fabric adapter communicatively coupled to a plurality of network ports, a plurality of controlling hosts, and a plurality of application hosts. The fabric adapter is configured to: receive contents of one or more headers of a network packet; receive control information for the network packet, the control information describing at least one of a state of a network or a state of an application running on at least one application host from the plurality of application hosts; receive a payload of a network packet; select a network path in the network; and forward the network packet to a network port of the plurality of network ports, the network packet including the one or more headers and the payload.

Abstract: A network device monitors a path aggregation group. The network device may monitor path selection for network traffic (e.g., packets) communicated through the path aggregation group. During a monitoring period, the network device may obtain a path selection indication that a network packet has been selected for communication through the path aggregation group and specifically a first path in the path aggregation group. The network device may update a path entry associated with the first path in the path aggregation group.
