We're developing a "hardware/kernel timestamp ping" for Linux in C. It's part of a complete SLA platform (appliance based on Debian with XMLRPC APIs). It's both a science project (Chalmers University, Gothenburg) and a commercial project (Tele2). Commercial SLA appliances from Cisco and Juniper typically have a accuracy of XXX microseconds. Our hardware ping, using Intel 82580 NICs, have an accuracy of 8 nanoseconds. That is VERY good. The reason for supporting IPv6 is, well, because it's the future ;) ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
