Dietz, et al. Standards Track [Page 1] RFC 5477 PSAMP Information Model March 2009 Abstract This memo defines an information model for the Packet SAMPling (PSAMP) protocol. It is used by the PSAMP protocol for encoding sampled packet data and information related to the Sampling process. As the PSAMP protocol is based on the IP Flow Information eXport (IPFIX) protocol, this information model is an extension to the IPFIX information model. Table of Contents 1.
