文章编号：1007-5321(2005)01-0039-04 多厂商设备环境中通道路由选择算法及应用 王 栋， 孟洛明 (北京邮电大学网络与交换国家重点实验室，北京 100876) 摘要：对多厂商设备环境下SDH(synchronousdigitalhierarchy)传送网中的自动通道路由选择问题进行了讨论， 提出了一种基于应用框架的简单有效的适配器设计方法：框架提供路由算法骨架，用适配器实现路由算法中因厂 商设备与网管接口而异的特定步骤．相应地给出了一种子网内通道路由有哪些信誉好的足球投注网站算法，并可根据网络中已有资源和网 管接口规则、有效地选择合适路由．应用上述方法和算法在实际网管系统中实现了自动通道路由选择功能． 关键词：同步数字序列；传送网；多厂商环境；应用框架；路由算法 中图分类号：TN915．07 文献标识码：A ChannelRoutingAlgorithmandApplicationunder Multi-VendorEnvironment WANGDong, MENGLuo-ming (StateKeyLaboratoryofNetworkingandSwitching,BeijingUniversityofPostsandTelecommunications,Beijing100876,China) Abstract: Issue of automatic channel routing in transport network under multi-vendor environmentwas analyzed for introductionofconciseandeffectivedesignofadapterbasedon application framework pattern. The framework provides skeleton of the routing algorithm, whereas individualadaptersfocuson implementingkeyoperationsthatarespecifictodifferent equipment types and associatedmanagement interfaces.A correlativechannelroutingalgorithm within sub-networkwasdiscussedwhich couldchooseappropriaterouteseffectivelyaccordingto theresourcesavailable in thenetworkandrulesdefinedbythemanagementinterfaces.Automatic channelrouting functionality in network management systemwas implementedby leveragingthe above-mentioneddesignandalgorithm.
