Jared, you mean: "Cost on the server" here not "cost on the router". I think, and I ask because at least some of Daniel's note implies, to my reading, that 'on the router' was your concern?
There's plenty of room for system call/interface improvements and hardware acceleration in UDP stacks, both of which should help with CPU concerns. Now that UDP may represent a significant portion of internet traffic, it will be easier for the necessary engineering expense to be justified.The explanation I got (which seems fair) from someone was that they only way to roll a new transport was to squat on some existing stuff that would make it through firewalls.If there's clearly a two-way flow occurring, i.e. as is the case with a
2 way flow means something on your home host or home gateway. It means very little at internet scale... since, in many cases, you -> server and server -> you are not sharing many of the same links / routers / etc. -chris
