Enabling an Energy-Efficient Future Internet Through Selectively Connected End Systems

Executive Summary

The Internet's architecture largely and implicitly assumes full-time connectivity, a notion that is embodied in key networking principles including fate sharing, soft state, and the end-to-end principle. In contrast, efforts to allow for more graceful operation in the presence of forced disconnectedness have recently been undertaken that change the underlying style of networking used by applications to accommodate both host-level and hop-by-hop disconnectedness (e.g., for deep space networks where connectivity depends on orbital mechanics). In this paper, the authors offer an initial exploration of the architectural constructs required to support selective connectivity, whereby a host can choose whether to be "Connected" or "Disconnected".
