Abstract: The existing transmission control mechanism lacks effective method in network
state estimation and packet loss differentiation. To deal with the problem, this paper
proposes a loss differentiation algorithm (LDA), utility based LDA (UBLDA) capable of
estimating the network state (congestion or not) by calculating utility parameters based on
the interval of packet arrival and sending rate. UBLDA can choose appropriate differentiation
scheme based on the state estimation, and integrate with a TCP friendly transmission
control protocol. It is a new multimedia transmission control mechanism suitable for wiredwireless
heterogeneous networks. Simulations are performed to compare the performance
of the proposed algorithm with existing methods.

Key words: transmission control, loss differentiation algorithm, heterogeneous network, congestion control, TCP friendly
