ITU-T SG 13 is standardizing broadband bearer connection control(B-BCC) protocol, which provides on-demand allocation of ATM channels between access network and service node. The existing B-BCC protocol recommends messages and procedures those are only related to the point-to-point connection. In this thesis, we extended the functions of B-BCC protocol to support point-to-multipoint connection, simplified the state diagram of the existing protocol to reduce the complexity, and added abnormal procedures. To check the correctness of the proposed B-BCC protocol, we modeled it usin the design language PROMELA, and validated it using the automated validation tool SPIN. |
