The existing edge routers can not assign the link capacities between User datagram protocol (UDP) subscribers and Transmission control protocol (TCP) subscribers to ensure the multiple priorities traffics with Differentiate‐Serve (DiffServ). To solve the problem, a new DiffServ edge router with Controlled‐UDP (C‐UDP) is proposed. The proposed DiffServ edge router can control the data rates of UDP and TCP subscribers according to their priorities. In the proposed edge router, there are multi‐queues buffers controlled by TCP Active queue management (AQM) and UDP AQM algorithms to implement fair and stable link capacities. The proposed TCP AQM and UDP AQM algorithms achieve the network congestion control and DiffServ by operating AQM parameters on the stable conditions proposed by us. The dynamic simulation results demonstrate the proposed edge router for DiffServ network to be valid.
