  3. 3. Shivkumar KalyanaramanRensselaer Polytechnic Institute 3 Plug fest The idea of group tests, or more formally known as a Plug fest, is one of several venues used by numerous technology consortiums. The venue is a means for providing vendors the opportunity to address potential ambiguities and to improve the testing scenarios and capabilities in a technology standard.
