摘要

研究了自动交换光网络(ASON)中的分层路由和波长分配问题。在此基础上，提出了多层最小负载路由算法(MLLR)、基于波长图的多层最小拥塞路由算法(WMLCR)和基于回溯的多层路由算法(BMR)三种自适应算法。提出并演示了支持该方案的AHORSP(基于ASON的分层最优路由与信令平台)平台。仿真结果表明，该算法具有实现方便、BP性能低、运行时间可接受等优点，具有广泛的应用前景。

Adaptive routing and wavelength assignment algorithms for hierarchical architecture in ASON

The hierarchical routing and wavelength assignment problem in Automatic Switched Optical Network (ASON) is researched. Based on our analysis, three adaptive algorithms called MLLR (Multi-Layer Least Loaded Routing Algorithm), WMLCR (Wavelength-graph-based Multi-Layer Least Congestion Routing Algorithm) and BMR (Backtracking-based Multi-Layer Routing Algorithm) are proposed. A platform named AHORSP (ASON based hierarchical optimal routing & signaling platform) supporting our routing scheme is proposed and demonstrated. The simulation shows that the proposed algorithms can have comprehensive application on the basis of their convenience to be realized, low BP performance and acceptable operation time.
