✦ Synopsis
This paper considers convergence type multimedia communication, where packet communications are executed concurrently from multiple information sources to a single destination node and discusses the priority assignment method for each link in each communication path. As the first step, the degradation is defined for each medium based on the average delay time in each communication path, and it is pointed out that the average, the maximum, and the variance of the degradation can be used as evaluation measures. Then, the priority assignment that minimizes the average degradation, as well as the priority assignment that minimizes the weighted sum of the maximum degradation and the variance of degradation, are discussed. An algorithm is presented for the former to derive the optimal solution, and another algorithm is presented for the latter to derive the quasi-optimal solution. Designs are tried for some network configurations using the proposed method, and their usefulness is verified.
