带内网络遥测（INT）是一种新的抽象，它允许数据包查询交换机内部的状态，如队列大小，链路利用率和排队延迟。我们原型INT在最近提出的P4语言使用软件开关作为实现平台。然后，我们将展示如何INT可以用来诊断性能问题，如间歇性的延迟尖峰。有关复制演示的说明，请访问http://git.io/sosr15-int-demo
In-band Network Telemetry (INT) is a new abstraction that allows data packets to query switch-internal state such as queue size, link utilization, and queuing latency. We prototype INT in the recently proposed P4 language using a software switch as the implementation platform. We then show how INT can be used to diagnose performance problems such as intermittent latency spikes. Instructions to replicate our demo are available at http://git.io/sosr15-int-demo
