可靠IP数据传输的研究

IP数据逐跳转发、尽力而为的方式无法保证非TCP类业务的可靠传输,目前已知的解决数据可靠传输的方法包括链路聚合、路径备份、链路备份等,也可以通过快速链路故障检测方法,使用标签转发技术及时规划另外的路径进行数据转发来保证数据的可靠传递。经过对这些方法的研究后提出的技术方法无需路由协议的参与,直接利用三层交换网络芯片和业务单元的逻辑处理能力完成IP数据的备份传输。

The hop by hop forwarding and best effort method of IP data cannot ensure the reliable transmission of non TCP services. At present, the known methods to solve the reliable transmission of data include link aggregation, path backup, link backup, etc. We can also use the fast link fault detection method and label forwarding technology to make a timely plan about another path for data forwarding to ensure the reliable transmission of data. After the research of these methods, the proposed technical method directly has the logic processing ability of three-layer switching network chip and service unit to complete the backup transmission of IP data without the participation of routing protocol.
