基于分离映射的混合交换路由系统设计与实现

摘要

The current Internet uses the best-effort IP packet mode to transmit,it forwards the packets in the same way without distinction and can not meet the diverse requirements of today's network services. To this end,propose a hybrid switching routing system based on separation map. Some of the data stream use the underlying physical resources to transmit the packets in circuit-switched mode directly, the other stream still use the best-effort IP packet forwarding mode,which is according to the characteristics of the data stream. It intro-duces the design and realization of the program in detail,tests its main function and verifies the feasibility of the program.%　　当今互联网采用“尽力而为”的IP分组转发模式进行数据包的传输,IP分组转发模式对所有的数据包进行一视同仁的转发而不加以区分,这种转发模式不能够满足当今网络服务多样性的要求。为此,文中提出了一种基于分离映射的混合交换路由系统,根据数据流的特性将某些数据流直接利用底层物理资源采用电路交换的方式进行数据包的传输,而对其他流仍然用IP分组进行尽力而为的转发。文中详细地介绍了该方案的设计和实现,并对其主体功能进行了测试,验证了该方案的可行性。
