(Embedded network communication. The RED algorithm is primarily used to manage network congestion. Since the packet loss rate in the RED algorithm has a linear relationship with the average queue length. As a result, the packet loss rate is larger when the network congestion is not serious. When the congestion ratio is severe, the packet loss rate is small and the congestion control capability is low. researched. The IMPRED algorithm was found to manage this problem, and the packet loss rate increased less rapidly when the average queue length was around the minimum threshold.)
