Thel broadband bearer connection control protocol: performance driven design and implementation

摘要

Broadband Access Networks (ANs) is a field of major activity in telecommunications technology. The V_B5 interface was introduced to support interconnection between these ANs and Service Nodes (SNs) that may be operated by different providers. The first version of V_B5 was V_B5.1, which provided static (provisioned) resource allocation in the AN. However, the need for more effective resource allocation became more and more demanding. The evolution of the V_B5.1 to the V_B5.2 was mainly a result of the Broadband Bearer Connection Control Protocol (B-BCCP). This protocol allows dynamic (on-demand) point-to-point or point-to-multipoint bearer connection establishment, modification and release at Virtual Channel level, under the control of SN. Implementation and simulation were performed to evaluate the performance of the B-BCCP and to establish the guidelines for its development. Various architectures of this system were examined and the results were compared and commended in this paper.
