Summary :

This paper proposes an analysis method of a priority scheme for mixed Continuous-Bit-Rate (CBR) and burst traffic contending based on Asynchronous Transfer Mode (ATM) which applied the future B-ISDN. The method is analyzed througn two separated source models; binary source model for burst traffic and random source model for CBR traffic. First we defines arrival process using the two source models according to traffic characteristics so that in adaptation to queueing modeling the system is analyzed through M/G/1/N. Next in view point of service process three priority schemes: push-out scheme, partial buffer sharing and separate route for each traffic loss are proposed. Here we impose two different priority classes on each source model. With the use of superposition of traffic from a number of independent random sources and binary sources, the partial buffer sharing scheme is proved to be best in three priority schemes for addmissible load and cell loss probability. In this paper, we propose partial buffer sharing scheme with priority scheme for two different traffics.
