The broadband bearer connection central protocol: performance driven design and implementation

Broadband Access Networks (ANs) is a field of major activity in telecommuni cations technology. The V-B5 interface was introduced to support interconne ction between these ANs and Service Nodes (SNs) that may be operated by dif ferent providers. The first version of V-B5 was V-B5.1, which provided stat ic (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 Co nnection Control Protocol (B-BCCP). This protocol allows dynamic (on-demand ) point-to-point or point-to-multipoint bearer connection establishment, mo dification and release at Virtual Channel level, under the control of SN. I mplementation and simulation were performed to evaluate the performance of the B-BCCP and to establish the guidelines for its development. Various arc hitectures of this system were examined and the results were compared and c ommended in this paper. (C) 1999 Elsevier Science B.V. All rights reserved.
