摘　　要：SDH 自愈环由于较高的生存性而成为光同步传输网很重要的一种网络拓扑结构。对自愈环的业务容量进行计算是规划环网络的重要依据。文中在自愈环业务容量的基础上,提出一种业务流量的计算方法,并给出了不同的自愈环的业务流量的计算公式及限制条件。The SDH self-healing ring has now become one important network topolo gy for the synchronous optical transmission network because of its relatively high sur- vivability.The calculation of service capacity of the Self-healing ring is a vital base for the planning of ring network.On the basis of service capacity of the self-healing ring, this paper presents a caculation method of traffic flow,and caculation formula of traffic flow as well as restriction conditions for different self-healing rings are also given.
