At CoNEXT ’15 in Heidelberg, Peter presented our paper on Monocle, our system for dynamic monitoring of OpenFlow switch dataplanes. Monocle is capable of fine-grained monitoring for the majority of rules, and it can identify a rule suddenly missing from the data plane or misbehaving in a matter of seconds. Also, during network updates Monocle … Continue reading “Presentation at CoNEXT ’15 on dynamic, fine-grained monitoring of OpenFlow switch dataplanes”
At the Symposium on Cloud Computing conference (SoCC) 2015, Kirill Bogdanov presented our work on performance debugging of replica selection algorithms in geo-distributed storage systems. We found bugs in widely-used systems, such as Cassandra and MongoDB. Kirill entered the Student Research Competition at SIGCOMM 2015 and described the work with this three-minute video [db-video id=”04o6v4e3″] … Continue reading “Presentation at SOCC ’15 on performance debugging of replica selection algorithms in geo-distributed storage systems”
At the Passive and Active Measurements Conference (PAM) 2015 in New York, Maciej presented our paper on detailed measurements of OpenFlow switch differences and performance characteristics. The abstract is as follows: SDN deployments rely on switches that come from various vendors and differ in terms of performance and available features. Understanding these differences and performance … Continue reading “Presentation at PAM ’15 on OpenFlow switch differences and performance characteristics”
Maciej presented our paper on the proposed transparent layer that relies on control and data plane measurements to confirm SDN (OpenFlow) rule updates only when the rule is visible in the data plane. The paper itself is available here. [db-video id=”c3rmil0f”]
Our paper titled “Providing Reliable FIB Update Acknowledgments in SDN” will appear at CoNEXT 2014 in Sydney. Maciej Kuzniar will present the work. Here is the abstract: In this paper, we first show that transient, but grave problems such as violations of security policies can occur with real switches even when using consistent updates to … Continue reading “Our upcoming CoNEXT ’14 paper: “Providing Reliable FIB Update Acknowledgments in SDN””
