The alternative of waiting for congestion and then reacting is much worse because once a network saturates, it does so at an exponential growth rate and reduces overall throughput enormously. It takes a long time for the queues to drain, and then all senders again repeat this cycle. By taking a proactive congestion avoidance approach, the pipe is kept as full as possible without the danger of network saturation. The key is for the sender to understand the state of the network and client and to control ...
