Description

一种提高分组传送网中复用段倒换效率的方法及装置Method and device for improving multiplex section switching efficiency in packet transmission network 技术领域Technical field
本申请涉及但不限于分组传送网(PTN：Packet Transport Network)领域。This application relates to, but is not limited to, the field of Packet Transport Network (PTN).
背景技术Background technique
随着技术的演进，承载网逐渐在向全网络之间互连的协议(IP：Internet Protocol)化方向演进，为了兼容已有的大量时分复用(TDM：Time Division Multiplexing)设备，PTN设备必须具备接入传统同步数字体系(SDH：Synchronous Digital Hierarchy)业务的能力，同时也必须兼容传统的SDH保护技术，因此PTN设备都实现了线性复用段保护。在PTN网络中实现复用段保护之后，由于业务的承载方式和传统的SDH网络存在比较大的差异，因此，在业务量比较大的时候容易出现倒换时间超标的问题。With the evolution of technology, the bearer network is gradually evolving in the direction of the Internet (Internet Protocol). In order to be compatible with the existing TDM (Time Division Multiplexing) devices, the PTN device must With the ability to access the traditional Synchronous Digital Hierarchy (SDH) service, it must also be compatible with the traditional SDH protection technology. Therefore, the PTN equipment implements linear multiplex section protection. After the multiplex section protection is implemented in the PTN network, there is a big difference between the bearer mode of the service and the traditional SDH network. Therefore, when the traffic volume is relatively large, the problem of excessive switching time is likely to occur.
在PTN网络中承载TDM业务都有实现控制字的处理，L比特是控制字的一个位，相关技术的相关处理如下：The TDM service is carried in the PTN network to implement the processing of the control word. The L bit is a bit of the control word. The related processing of the related technology is as follows:
(1)客户侧检测到信号失效后设置L比特置位，检测到客户信号恢复后取消L比特置位。(1) After the client side detects the signal failure, the L bit is set, and the L bit is set to be canceled after detecting the recovery of the client signal.
(2)在网络侧检测到收到的伪线报文L比特置位，认为远端的客户信号失效，需要向本端的客户侧下插告警。(2) When the L-bit of the received pseudo-line packet is detected on the network side, it is considered that the remote client signal is invalid, and the alarm needs to be inserted into the client side of the local end.
(3)网络侧的数据发生中断时需要向TDM业务的客户侧下插告警。(3) When the data on the network side is interrupted, an alarm needs to be inserted into the client side of the TDM service.
由于在复用段倒换的过程中不可避免地会出现一些客户侧或者网络侧的一些告警，在此过程中这些控制字相关的功能在参与业务处理时会增加一些复杂性，最终使得倒换时间超标。In the process of multiplex section switching, some alarms on the client side or the network side will inevitably occur. In this process, the functions related to these control words will add some complexity when participating in the service processing, and finally the switching time exceeds the standard. .
