Transport Flow Optimization
Transport Flow Optimization (TFO) is the fundamental layer of WAAS WAN optimization. It provides optimizations that improve TCP behavior under problematic network conditions such as latency, packet loss, retransmission, and congestion. With TFO, communication nodes in the branch and data center are shielded from the WAN conditions, and Cisco WAAS manages the WAN challenges on behalf of the network nodes. This technique ensures efficient utilization of WAN capacity. It also mitigates the impact of packet loss and congestion and increases the throughput of the WAN circuit. Other optimizations employed by WAAS are called ...
