Abstract
Disclosed are techniques regarding interfaces, each configured to output network packets. The techniques can include a memory storing a first multipath group associated with the interfaces and a routing table containing routes to the first multipath group. The techniques can further include congestion detection logic configured to determine that an interface of the first multipath group is congested from a flow of network packets, the flow of network packets directed to the first multipath group from a route of the routing table. The techniques can additionally include congestion avoidance logic configured to, upon determining that the interface of the first multipath group is congested, dissociate the route from the first multipath group and associate the route with a second multipath group, the second multipath group associated with the interfaces of the first multipath group.
