The BOF will examine the need for a standard set of capabilities for network elements to sample traffic. One motivation to standardize these capabilities comes from the requirement for measurement-based support for network management and control across domains. This requires domain wide consistency in the types of sampling schemes available, the manner in which the resulting measurements are presented, and consequently, consistency of the interpretation that can be put on them. The capabilities are positioned as suppliers of packet samples to higher level consumers, including both remote collectors and applications, and on board applications.
