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——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。 The traditional self-healing ring can be divided into one-way ring and two-way ring, both of which have certain deficiencies in resource allocation. Based on the two kinds of ring structure, this paper proposes a new ring network structure - hybrid ring based on the principle of resource allocation and optimization, and presents a resource allocation algorithm suitable for hybrid ring. The calculation results show that the ring structure is superior to the traditional ring structure in resource allocation, and has certain advantages in saving network resources.
