[Executive Summary from our annual report for 2010.]
This annual report covers CAIDA’s activities in 2010, summarizing highlights from our research, infrastructure, data-sharing and outreach activities. Our current research projects span topology, routing, traffic, economics, and policy. Our infrastructure activities support several measurement-based studies of the Internet’s core infrastructure, with focus on the health and integrity of the global Internet’s topology, routing, addressing, and naming systems.
In light of available data on global IPv6 deployment, ISPs, and those who build equipment for them, have already accepted that multi-level network address translation (NAT, between IPv4 and IPv6 networks) is here for the foreseeable future, with all its limits on end-to-end reachability and application functionality, and its required unscalable per-protocol hacks. Whether “carrier-grade” NAT (CGN) technology supports a transition to IPv6 or becomes the endgame itself is irrelevant to the planning horizon of public companies, who must now develop sustainable business models that accommodate, if not support, IPv4 scarcity. I’ve heard a few notable predicted outcomes from engineers in the field.
