In this paper, we present the Enhanced Communication Transport Protocol–Part 5 (ECTP‐5), which provides scalable and reliable multicast communication service for many‐to‐many applications by constructing high quality recovery trees from two‐layer logical trees and repairing the losses via unicast automatic repeat request–based error control. In order to realize the protocol, we developed feasible protocol architectures and building blocks including additional functions which deal with engineering details, such as membership dynamics and sender coordination. Experimental results show that ECTP‐5 scales well with various session sizes and packet loss rates in terms of control overhead and recovery latency.
