Leveraging SDN layering to systematically troubleshoot networks
Brandon Heller,Colin Scott,Nick McKeown,Scott Shenker,Andreas Wundsam,Hongyi Zeng,Sam Whitlock,Vimalkumar Jeyakumar,Nikhil Handigol,James McCauley,Kyriakos Zarifis,Peyman Kazemian +11 more
TL;DR: This position paper advocates a more structured troubleshooting approach that leverages architectural layering in Software-Defined Networks (SDNs), and shows how recently-developed troubleshooting tools fit into a coherent workflow that detects mistranslations between layers to precisely localize sources of errant control logic.
Proceedings ArticleDOI
Troubleshooting blackbox SDN control software with minimal causal sequences
Colin Scott,Andreas Wundsam,Barath Raghavan,Aurojit Panda,Andrew Or,Jefferson Lai,Eugene Huang,Zhi Liu,Ahmed El-Hassany,Sam Whitlock,Hrishikesh B. Acharya,Kyriakos Zarifis,Scott Shenker +12 more
TL;DR: This paper presents a technique for automatically identifying a minimal sequence of inputs responsible for triggering a given bug, without making assumptions about the language or instrumentation of the software under test.
Proceedings ArticleDOI
PEERING: An AS for Us
TL;DR: This paper proposes a new class of interdomain research: researchers can instantiate an AS of their choice, including its intradomain topology and interdomain interconnectivity, and connect it with the "live" Internet to exchange routes and traffic with real interdomain neighbors.
Proceedings ArticleDOI
Ripcord: a modular platform for data center networking
Brandon Heller,David Erickson,Nick McKeown,Rean Griffith,Igor Ganichev,Scott Whyte,Kyriakos Zarifis,Daekyeong Moon,Scott Shenker,Stephen Stuart +9 more
TL;DR: The Ripcord demo will show three examples of custom network functions, operating together, on top of a 160-node cluster, with a visualization of live parameters for each link and switch, such as bandwidth, drops, and power status, as well a control panel to modify the traffic load.
Book ChapterDOI
Diagnosing Path Inflation of Mobile Client Traffic
Kyriakos Zarifis,Tobias Flach,Srikanth Nori,David Choffnes,Ramesh Govindan,Ethan Katz-Bassett,Z. Morley Mao,Matt Welsh +7 more
TL;DR: This work identifies the key elements that can affect the Internet routes taken by traffic from mobile users (client location, server locations, carrier topology, carrier/content-provider peering), and develops a methodology to diagnose the specific cause for inflated routes.
