Abstract
Performance measurements are taken in a data network where information from a source is sent to a set of receivers via a plurality of routers using multicast addressing by generating a performance measurement packet having indicia indicating that the packet is a performance measurement packet at the source. The performance measurement packet is forwarded from the source to a subset of one or more identified receivers over the same respective paths as non-measurement packets. The performance measurement packets are received at the subset of identified receivers, but not at receivers in the set that are not part of the subset.
