Reed I find "EDF" and = "ACID". Those aren't standard bufferbloat jargon, but come from elsewhere in = computer science. EDF is Earliest Deadline First (a scheduling policy = normally applied in RTOSes - Realtime Operating Systems), and ACID is = Atomicity, Consistency, Isolation, Durability (a set of properties = typically desirable in a database). I think the main distinction between online gaming and teleconferencing = is the volume of data involved. Games demand low latency, but also = usually aren't throwing megabytes of data across the network at a time, = just little bundles of game state updates telling the server what = actions the player is taking, and telling the player's computer what = enemies and other effects the player needs to be able to see. = Teleconferencing, by contrast, tends to involve multiple audio and video = streams going everywhere. - Jonathan Morton
