Abstract:
Aspects of this disclosure provide techniques for dynamically configuring flow splitting via software defined network (SDN) signaling instructions. An SDN controller may instruct an ingress network node to split a traffic flow between two or more egress paths, and instruct the ingress network node, and perhaps downstream network nodes, to transport portions of the traffic flow in accordance with a forwarding protocol. In one example, the SDN controller instructs the network nodes to transport portions of the traffic flow in accordance with a link-based forwarding protocol. In other examples, the SDN controller instructs the network nodes to transport portions of the traffic flow in accordance with a path-based or source-based transport protocol.
