Abstract

Methods and apparatuses for communicating data within measurement traffic are described. Embodiments that send, receive and both send and receive are described. Some embodiments are described that compute statistics based at least partly on measurement traffic. Some embodiments are described that communicate computed statistics within measurement traffic. Some embodiments are described that rank and select paths based at least in part on computed statistics.
