摘要
介绍了SDH几种组网方式:链形、星形、树形、环形和网孔形,就电力专网常用的组网方式:链形网、二纤单向通道保护环、二纤双向复用段保护环、四纤双向复用段保护环等的工作原理与优缺点进行分析,阐述了利用ASON进行Mesh组网的先进技术,并对电力专网的建设提出了一些建议。
The paper introduced some networking modes such as type chain, star network, tree structure, ring and mesh structure. Also, special electrical network includes chain network, two-fiber unidirectional path protection ring, two-fiber bidirectional muhiplex section protection ring and four-fiber bidirectional multiplex section protection ring. The paper analyzed their healing theory as well as merits and drawbacks. At last, technology of Mesh networking by ASON was presented and some suggestions for special electrical network construction were proposed.
