NeTS: Small: BugWatch: Towards Detecting and Reacting to Network-Data-Plane-Disrupting Bugs

点击翻译按钮获取中文摘要

Network-data-plane-disrupting bugs can cause the disruption ofcritical network applications. Unfortunately, today, there exists nocomprehensive solution for detecting data-plane-disruptingbugs. Consequently, the network operator has few useful leads forinvestigating bug-triggered problems. To bridge this gap, this projectdevelops novel measurement-based solutions for automatic bug detectionthat are accurate and scalable. The results from this project willsignificantly improve the reliability of current and future generationnetworks. The expected results include network measurement techniques,data analysis methods, network-wide monitoring strategies, datastructures and algorithms for high performance bug detection, and buglocalization techniques. These solutions will (1) save IT personnelresources because network operators no longer need to troubleshoot anentire complex network but instead can focus on finding the bestsolution for a detected bug; (2) reduce negative impact of bugsbecause the operator can immediately take proper defensive actions;(3) improve assurance after software or hardware updates sinceincorrect data plane behaviors resulting from updates could beautomatically caught; (4) improve feedback to vendors since vendorscan receive valuable information correlating detected bugs toconfigurations, updates, configuration changes, etc., which helpsvendors diagnose the problem's root cause and develop solutions. Theresults from this project will be broadly disseminated throughscientific workshops, conferences and journals, as well as through aproject web site hosted at Rice University. Software and tools thatare produced by this project will be released to the public under opensource licenses.
