基于TCP交换的电路交换与分组交换融合方法

宽带实时网络业务的发展使得分组交换逐渐不能满足提供高服务质量(QoS)保证的要求，融合电路交换与分组交换以形成优势互补已成为网络技术发展的迫切需求。基于该需求，提出了融合电路交换与分组交换的基于TCP交换的新方法。以网络核心使用电路交换，提高核心带宽利用率；在网络边缘采用分组交换的技术，发挥其方便灵活组网模式。文章分析了TEP交换需要解决的主要问题，在此基础上较详细的讨论了，TCP交换中由IP路由协议创建与撤销电路链路的过程；分析了边界路由器与核心路由交换机所需完成的主要功能与任务；实现TCP交换所必须研究的关键技术。

Integration of Circuit Switching and Packet Switching Based on TCP Switching

with the development of broad band real-time network operation, Packet Switching characterized by best-effort cannot offer high quality of service (QoS) gradually, integration of Circuit Switching and Packet Switching for complementary advantage becomes the urgent need for network technology development, based on which the paper explore a new method--integration of Circuit Switching and Packet Switching based on TCP Switching. Circuit Switching used in core network for higher utilization of bandwidth and Packet Switching used in edge network for convenience and flexibility compose the network structure, we discussed main problem should be resolved in TCP Switching and procedure of circuit link establishment and deletion by IP routing protocol, also analyzed main function and role of the border router and core switcher, key technology must be studied for implementation of TCP Switching.
