1 Prototyping and Evaluation of Mobility First Architecture Kiran Nagaraja, Ivan Seskar Rutgers, The State University of New Jersey Contact: nkiran (at) winlab (dot) rutgers (dot) edu NSF FIA MobilityFirst Project - EAB Meeting Feb 28, 2011

2 Goals Prototype and demonstrate the working of the Mobility First architecture at Internet scale Focus on application scenarios and solutions that address mobility challenges Identify evaluation and deployment options for overall architecture as well as those to evaluate sub components Address challenges of large scale deployment Emulating realistic topologies and data traffic Target production quality software for live deployment Span multiple campus/testbed sites Opt in users and real applications Feb 28, 2011 Page: 2
