ABSTRACT So what is all this DTN research about anyway? Sceptics ask: Why are there no DTN applications? , or Why is DTN performance so miserable? This article attempts to address some of these complaints. We present suggestions of expectations for applications, and metrics for performance, which suggest a more tolerant view of research in the area.

The last few years have seen an explosion in DTN research, with several papers in the main SIGCOMM conference, and more speci c venues such as the CHANTS workshop2 which is now in its fourth year. At the same time, however, there remains some scepticism about the need for a new DTNlike architecture. This article is
