Delay Tolerant Networking (DTN) has been proposed both as a technology to address challenges faced by 'extreme' network and as a way to deliver low-cost networking in underserved areas. Although this technology has great potential, the current DTN architecture suffers from several problems. In this talk, I will first present an overview of DTN motivations and the DTN Research Group architecture. I will then present the limitations of this architecture and ongoing work at UW that addresses them.
