ASON分层路由地址空间定义方式及其系统试验

ASON hierarchical common name space definition scheme in large systems

为解决现有地址空间在层域管理中的不足,针对自动交换光网络(A SON)分层分域控制的关键问题,对地址空间定义和层域管理展开研究,提出了一种基于统一地址空间的新的分段地址定义方案,并构建了大规模A SON试验平台以测试该地址空间定义下系统的功能和性能。该地址空间定义方式通过地址的特定结构表示网络的层域结构,简化了网络寻址过程和层域关系维护过程。测试结果表明:这种分段结构的地址定义方式完全满足A SON层域管理的要求,同时因为不需要维护额外的地址映射表,能有效降低现有地址空间需要额外维护地址映射表造成的额外开销,提高系统稳定性。

Existing name space definitions in automatically switched optical network （ASON） hierarchical routing always suffer from limitations. A sectioned common name space definition method was developed and used to build a large ASON hierarchical routing testbed. Tests of the sectioned name space definition method show that the method provides effective control and management of the hierarchies. Since no extra mapping of the hierarchies is needed, the method efficiently reduces the mapping table maintenance costs and increases network stability.
