In the modern era of software‐defined networking (SDN), network monitoring is becoming more important for providing information about a network and helping SDN controllers to make decisions about the network. In‐band Network Telemetry (INT) is a new network monitoring framework that collects packet‐level network information to provide real‐time and fine‐grained network monitoring. In this paper, we present the design of the overall INT management architecture and its two main components: the INT management system and INTCollector. The INT management system controls heterogeneous INT‐capable devices through a common interface. INTCollector is a high‐performance collector for INT data, which uses eXpress Data Path and an event detection mechanism. The evaluation result shows that INTCollector processes telemetry reports 27 times faster than other packet‐level telemetry collectors. We made the implementation as open source, to make researchers who are interested in INT implement their own ideas on top of our work.

使用带内网络遥测实时和细粒度的网络监控

在软件定义网络（SDN）的现代时代，网络监视对于提供有关网络的信息并帮助SDN控制器做出有关网络的决策变得越来越重要。带内网络遥测（INT）是一个新的网络监视框架，该框架收集数据包级别的网络信息，以提供实时和细粒度的网络监视。在本文中，我们介绍了整体INT管理体系结构及其两个主要组件的设计：INT管理系统和INTCollector。INT管理系统通过公共接口控制具有INT功能的异构设备。INTCollector是用于INT数据的高性能收集器，它使用eXpress数据路径和事件检测机制。评估结果表明，INTCollector处理遥测报告的速度比其他数据包级遥测收集器快27倍。我们以开源的形式实现了该实现，以使对INT感兴趣的研究人员在我们的工作之上实现自己的想法。
