A NEW ACCESS-CONTROL METHOD BASED UPON FRAME ADDRESSING FOR DISTRIBUTED ACCESS SUBSCRIBER NETWORK

A distributed access network in which the optical fiber is shared amon g terminals through media access control has been examined as the subs criber part of broadband integrated services digital network (B-ISDN). In a distributed access subscriber network, unlike peer-to-peer commu nications which can be seen in local area networks, the main traffic f lows are between exchange node and terminals. Therefore, a new access control scheme based on this characteristic should be developed. In th is paper, a new access control method based on frame addressing is pro posed and simulation analysis is performed. Compared with other method s, it is shown that, by employing cyclic reset and back-pressure mecha nism into the access control, a fair and efficient network access can be achieved for various types of traffic.
