Electronics Nuclear engineering Rapid growth of Internet traffic and the increase of new user applications authorize the development of new internet infrastructure. Congestion remains the major problem that affects the Internet service quality. Avoiding packet drops keeps network bandwidth and permits congestion signals to be propagated faster. Sending congestion information is essential to the network performance. Using Explicit Congestion Notification (ECN) to notify the source about the network congestion can result in sending congestion signal faster so that the sender can reduce its congestion window sooner which leads to better network utilization.
