Large Flow Classification in Flow Aware Transport over PSN

Network traffic has shown the combination of few very high bit rate flows (large flow) and a huge amount of very low bit rate flows (small flow), which causes uneven load balance over ECMP or LAG. Differentiating large flow and small flow packets in IP/MPLS networks enables an enhanced ECMP transport. Enhanced ECMP applies different distribution methods to large flow packets and small flow packets to improve the load balance and congestion control. This draft proposes large flow classification scheme for flow awareness transport in PSN.
