This is a manual for the nettimer program. Nettimer is a tool for measuring network bandwidth. It can measure all the link bandwidths along a path or just the bottleneck link. It can measuring existing traffic passively or do active probing. It can measure at one host or at multiple hosts in concert. In this manual I describe the purpose, functionality, installation, parameters, and output of the nettimer program.
