SDH自愈混合环及其容量优化分配算法

传统的自愈环可分为单向环和双向环，这两种结构在资源配置时都有一定的不足之处。本文在两种环结构的基础上，从实践出发，以资源配置优化为原则提出了一种新的环形网结构０混合环，并给出了一种适用于混合环的资源配置算法。计算结果表明，这种环结构在资源配置方面优于传统的环结构，在节约网络资源方面有着一定的优势。

A new self-healing mix-direction ring for SDH and The Algorithm of its capacity assignment optimization

There are two kinds of traditional self-healing ring , one is uni-direction ring and the other is bi-direction ring. Both structures of ring are of some shortages for resource configuration. Accordingly, a new structure of self-healing ring together with associate resource configuration algorithm is proposed. This type of mix-direction self-healing ring can save the communication resource effectively. Results of simulation demonstrate that the mix-direction self-healing ring is superior to the traditional ones. This research will benefit to meet the rapid increase of the communication demand.
