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。
In order to solve the shortage of the existing address space in the layer management, aiming at the key problems of A SON hierarchical control, this paper studies the definition of address space and layer management, Space, a new segmentation address definition scheme, and built a large-scale A SON test platform to test the function of the system under the definition of address space and performance. This address space definition mode represents the layer structure of the network through a specific structure of the address, which simplifies the network addressing process and the layer relationship maintenance process. The test results show that the address definition mode of this segment structure completely meets the requirements of the A SON layer management, and at the same time, the extra address mapping table is not needed to effectively reduce the additional overhead caused by the additional address map maintenance in the existing address space Overhead, improve system stability.
