In order to control and manage the high speed networks congestion phenomena in general and Frame Relay (FR) congestion problem in particular, priority-based mechanisms are proposed in the litterature for fixed length data units. In this report, we have proposed a markovian model related to Partial Buffer Sharing (PBS) mechanism for variable length data units. The thorough performance evaluation for $M^{(1)} + M^{(2)}$/D/1/N with PBS mechanism queue has been conducted. We have shown the best performance of this mechanism compared with those of $M^{(1)} + M^{(2)}$/D/1/N without PBS mechanism queue. We have also discussed the parameters model choice.
