双向主动测量协议 （TWAMP）
云原生路由器支持双向主动管理协议 （TWAMP），用于测量和监控 5G 传输网络中的网络性能。它支持托管和轻量级 TWAMP。
RFC 5357 中描述的双向主动管理协议 （TWAMP） 是一种网络性能测量和监控服务，用于 5G 传输网络的主动性能监控。TWAMP 是单向主动管理协议 （OWAMP） 的扩展，提供双向或往返测量，而不是单向功能。双向测量不需要本地和远程时钟同步。远程主机支持可以限制为简单的回显功能。TWAMP定义了一个开放协议，用于使用时间戳以比其他方法更准确地测量双向或往返指标，同时考虑处理延迟。有关更多详细信息，请查看 了解双向有源测量协议 主题。
云原生路由器支持两种 TWAMP 实现方式：
- 托管 TWAMP — 在控制客户端和响应方服务器之间建立 TCP 控制连接，用于交换测试会话信息。测量和监控测试在会话发送方和会话反射方之间运行。
- Light TWAMP — 控制客户端和响应方服务器之间未建立控制连接。会话发送方直接使用会话反射器运行测量和监控测试。会话反射器不知道会话状态。
请注意以下云原生路由器行为，用于对 TWAMP 测试数据包进行时间戳记：
- TWAMP会话发送方发送的测试数据包的时间戳由应用程序设置
-
TWAMP 会话反射器接收的测试数据包的时间戳由内核设置
- TWAMP 会话反射器反射的测试数据包的时间戳由应用程序设置
-
TWAMP 会话发送方接收的反射数据包的时间戳由内核设置
配置
您可以使用最少的配置配置 TWAMP 服务器和客户端。还有一些具有默认值的附加配置参数，可以根据您的要求进行修改。请查看 编辑服务 rpm twamp 命令以获取有关每个配置选项的更多信息。下表提供了选项的默认值：

注意：
默认情况下，客户端控件连接 test-count 设置为零。在这种情况下，TWAMP测试会在配置提交后自动启动，并继续运行，直到配置被删除。如果 test-count 配置为非零值，则必须使用以下命令启动或停止 TWAMP 测试：
user@host> request services rpm twamp start client control-client-name user@host> request services rpm twamp stop client control-client-name
验证
您可以使用命令 show services rpm twamp client probe-results 验证 cRPD shell 上的 TWAMP 探测结果：
user@host> show services rpm twamp client probe-results
