To fundamentally improve the efficiency of content distribution in the network, information-centric networking (ICN) has received extensive attention. However, the existence of a large number of IP facilities in the current network makes the smooth evolution of the network architecture a realistic requirement. The ICN architecture that separates the process of name resolution and message routing is widely accepted for its better compatibility with IP networks. In this architecture, the user first obtains the locator of the content replica node from the name resolution system (NRS) and then completes the data transmission through the locator. In data transmission, receiver-driven congestion control algorithms need to be studied. Therefore, we introduce the Copa algorithm into ICN and propose an improved Copa-ICN algorithm. Experiments show that the Copa-ICN algorithm has a high convergence speed and fairness, and when there is a transmission process in the opposite direction, it can still have a high throughput different from the original Copa algorithm.
