Abstract

In this paper, we proposed the request-counter MAC protocol for a broadband access network using an ATM-PON supporting CBR/rtVBR, nrtVBR, UBR and ABR traffic. For this, we present grant field format, minislot format, and dynamic bandwidth allocation algorithm. The proposed MAC protocol applies the different priority to permit distribution process. CBR/rtVBR traffic, with the stringent requirements on CDV or delay, is allocated prior to any other traffic class. nrtVBR traffic such as Internet traffic, which has non-strict CDV or delay criteria, uses flexibly the available bandwidth. UBR traffic is allocated with lowest priority for the remaining capacity. The performance of proposed MAC protocol is evaluated in terms of 1-point CDV with various offered load. From the simulation result, we have confirmed that our proposed scheme can reduce the average cell delay in comparison to that of conventional MAC schemes.
