Fishbowl Teleseminar: The Challenge of Cellular-Internet Convergence: Rethinking the Internet Architecture to Support Mobility Services as the Norm

October 17, 2013 @ 3:00 pm - 5:00 pm

D. Raychaudhuri
WINLAB, Rutgers University



This talk provides a discussion of one of the central design challenges associated with next-generation cellular systems – that of effectively converging mobile networks with the global Internet. Although the trend towards “flat” IP-based solutions for cellular networks is well under way with 4G/LTE, a significant rethinking of the architecture will be needed to achieve the goal of supporting mobile devices and applications as “first-class” services on the Internet. Several anticipated mobility service scenarios including hetnet/small cell, multi-network access, M2M (machine-to-machine) and V2V (vehicle-to-vehicle) are examined and related network service requirements such as user mobility, disruption tolerance, multi-homing and context-aware messaging are identified. Drawing from our experience with the ongoing NSF-sponsored “MobilityFirst” future Internet architecture project, we outline a possible protocol solution based on the “GUID (Globally Unique Identifier) Service Layer” which enables a clean separation of naming and addressing, and provides intrinsic support for a wide variety of mobility services. The talk concludes with a brief discussion of the MobilityFirst proof-of-concept prototype currently being deployed on the GENI meso-scale networking testbed.
