[LY] Hash works well for short flows. That was developed when Internet is primarily used for data transport. As more and more video data on Internet, traffic become mixed with long flows with many packets and short flow with few packets. Hash no longer works well in this traffic pattern. > > > > > [LY] the server load balance and the network path load balance have > > different criteria. > > Very true. It isn't clear to me that balancing the network load > without knowledge of the server load is a good idea. [LY] Agree. However, today network performs load balance without considering server load balance; server load performs load balance without considering network load balance. Two operations are independent.
