• A unified implementing code for all variants of single buffer is proposed.
• The method is based on the uniformization technique that is numerically stable.
• A numerical analysis shows that MAM may be inaccurate: probability exceeding 1.
• Less sensitive in computational time to the number of plotted points than MAM.
• A real application of the theoretical results on a video traffic is achieved.
This paper is interested in the asymptotic distribution of fluid models with finite or infinite buffer capacity. The probability distribution of the buffer content is controlled by a linear differential system with specific boundary conditions. All earlier methods are forced to test the singularity of the drift matrix before starting any computation. Also, the finite and infinite buffer capacity cases are treated differently. Our approach leads to a unified algorithm which is able to compute simultaneously the buffer workload distribution for finite and infinite buffer capacity without looking into the drift matrix singularity. The proposed method is not spectral and it is based on the uniformization technique. An example of a video traffic is firstly modeled by a Markovian fluid and secondly analyzed.
