摘　　要：该文提出了可变传输链容量的思想,并研究了传输链容量可变性对带宽优化分配结果的影响。计算实例表明,在总和不变前提下的各传输链容量的有限可变性,对提高网络为突发性业务的服务质量有重要贡献。The concept of variable capacity of a transmission link is proposed and the impact of the variability of transmission link capacities on the optimal path bandwidth allocation is studied.Example shows that under the constraint that the sum remain fixed,the limited variability of the capacities of each transmission link takes an important part in improving the quality of service for burst traffics.
