A Gilbert-gamma topology is proposed to model packet-loss processes in UDP connections. The proposed topology introduces state duration modelling with gamma distributions. When compared with the ordinary Gilbert model the proposed topology substantially improves the likelihood of observed packet-loss processes, and gives reductions as high as 70% in the subjective estimation of speech quality transmitted over IP networks. The results presented can be easily applied to other real-time applications such as audio and video streaming.
