Saptarshi Guha (author of the Rhipe package) joins the likes of Ebay, Yahoo, Twitter and Facebook and as one of just 37 presenters at the Hadoop World conference. (Revolution Analytics is proud to sponsor Saptarshi's presence at this event, which take place in New York on October 12.) He'll be talking about using R and Hadoop to analyze Voice-over-IP network data for Quality of Service, as explained in this abstract:
RHIPE is an R package that integrates the R environment for statistics and data analysis with the Hadoop distributed computing framework. With RHIPE, the user can store and compute with large and complex data sets using R functions and programming idioms. In this talk, I will demonstrate the use of RHIPE to analyze 190Gb of VoIP network data for QoS. The jitter between two consecutive packets is the deviation of the real inter-arrival time from theoretical. We show jitter follows desired properties and is negligible, which supports the assumption of the measured traffic being close to the offered traffic.
Saptarshi explains more about his talk, and his work with Hadoop and R, in this interview at the Cloudera blog.
