The invention discloses an improved-
transmission control protocol-friendly
multicast congestion control (TFMCC)-protocol-based communication method, which is implemented by the following steps of: every time when a source receives a feedback data packet from a
current limiting receiver (CLR), computing end-to-end one-way
delay jitter between the source and the CLR according to effective
timestamp information in the feedback data packet, and computing a congestion judgment factor by utilizing the
delay jitter to judge congestion; and computing a correction factor by utilizing the congestion judgment factor to regulate expected
throughput and further regulate a
transmission rate. In the method, the
transmission rate is regulated by calculating the end-to-end
delay jitter between the source and the CLR as a congestion
signal, and the end-to-end delay jitter of a TFMCC protocol is effectively controlled, thereby effectively reducing the jitter of the protocol, average end-to-end delay, average end-to-end delay jitter, an average
packet loss rate and the like, improving the stability and overall performance of the TFMCC protocol, and making the protocol better serve a
multicast protocol and more suitable for the transmission of
multimedia services.
