| Research Abstract |
This research aims to propose a framework of the integrative traffic control for broadband communication system with multiple channels. We investigated the integrated traffic of multiple media and the performances of TCP (transmission control protocol) in the communication system with large bandwidth-delay product. Based on the preceding study, we proposed two dynamic error control schemes under the consideration of the states of the channels. The performances of the proposed schemes have been evaluated by the analytic method and computer simulation. We obtained the closed-form expression of the throughput efficiency at the case of two channels. Compared with the existing scheme, the effectiveness of the proposed schemes is shown by the numerical results.
