Traffic between a source-destination pair is then split between the primary and secondary LSPs using an ABR-like explicit-rate feedback gathered from the network. Taking into consideration the packet reordering effect of packet-based load balancing schemes, we propose a novel traffic splitting mechanism that operates on a per-flow basis. We show using a variety of scenarios that deploying Bow.hased multipath traffic engineering not only provides significantly and consistently better throughput than that of a single path hut is also void of any packet reorderings.
