Abstract content

The effects of increasing the root zone KSK size are studied by replaying trace data from a.root-servers.net to different name server processes with different ZSK (and KSK) parameters. This work explores how differing key sizes might affect root server operations in terms of (a) percent of UDP responses with TC bit set; (b) the distribution of response sizes over both UDP and TCP; (c) the amount of fragmented UDP responses; and (d) traffic volume (bandwidth). We consider both normal operations and key rollover scenarios.
