一种新型交换式路由器模型

针对路由器结构日趋复杂、越来越不堪重负的情况,分析了主干网与非主干网对路由器的不同需要,把路由选择转发的工作进行了合理的分摊,提出了由“边界路由器“BSR与“中心路由器“CSR两级路由器共同完成分组转发的模型。模型提出了解决“信元税“（cellrate）问题的智能分段策略和在BSR端对重点目标实现旁路转发的安全审计方案。

Model for a New Changeover Router

In consideration of the status of more and more complexed structures and hardly standing heavy loads still further, different demands for master networks and non-master networks of routers are analyzed. The rational allocation of route selection and conversion is made, a model for grouping conversion implemented by BSR router and CSR router is proposed. Intelligent section strategy for solving the problem of "cellrate" and safe auditing project of bypass conversion to the key object of BSR end are described in the model.
