Abstract: The improved consecutive message transmission and adaptive buffer control (ICMTABC) collaboration model proposed in this paper is an enhancement of the existing CMTABC version. The motivation is to provide better collaboration performance for distributed applications, such as network-based computer-supported cooperative design. The enhancement is achieved through better reliability for end-to-end communication channels over the Internet. The CMT and ABC mechanisms are adaptive; the former improves message transmission and reception and the latter prevents message loss due to buffer overflow at the reception side. The anticipative capability of the ICMTABC framework comes from the convergence algorithm (CA) element, which is an internet end-to-end performance measurement (IEPM) mechanism that predicts the mean message response time of a communication channel quickly, responsively and accurately. The CA predictions provide the basis for computing the QoS factors needed by CMT and ABC for anticipative and adaptive control.

Keywords: collaboration; internet; consecutive message transmission; adaptive buffer control; QoS factors; convergence algorithm; anticipative.
