I2RS Large Flow Use Case Demands on networking bandwidth are growing exponentially due to applications such as large file transfers and those with rich media. Link Aggregation Group (LAG) and Equal Cost Multipath (ECMP) are extensively deployed in networks to scale the bandwidth. However, the flow based load balancing techniques used today make inefficient use of the bandwidth in the presence of long lived large flows. This draft presents a use-case to improve the efficiency under such conditions and aims to drive requirements for the I2RS WG.
