WebMar 17, 2024 · We summarize the efforts in two categories: flow-level load-balancing and packet-level load-balancing. Flow-level load balancing. ECMP (Equal Cost Multiple Path) is a standard forwarding scheme which is supported by commodity switches. ECMP distributes traffic across equal-cost paths based on flow hashing. WebDepending on the type of traffic that needs to be distributed into an ECMP or a LAG, different variables are used as input to the hashing algorithm. An option is provided per LAG to select the hashing function to be used for load-balancing flows on the member ports of the LAG. Users can use one of the available options based on the flows they ...
