RFC5474 - A Framework for Packet Selection and Reporting
This document specifies a framework for the PSAMP (Packet SAMPling) protocol. The functions of this protocol are to select packets from a stream according to a set of standardized Selectors, to form a stream of reports on the selected packets, and to export the reports to a Collector. This framework details the components of this architecture, then describes some generic requirements, motivated by the dual aims of ubiquitous deployment and utility of the reports for applications. Detailed requirements for selection, reporting, and exporting are described, along with configuration requirements of the PSAMP functions. This memo provides information for the Internet community.
RFC5475 - Sampling and Filtering Techniques for IP Packet Selection
This document describes Sampling and Filtering techniques for IP packet selection. It provides a categorization of schemes and defines what parameters are needed to describe the most common selection schemes. Furthermore, it shows how techniques can be combined to build more elaborate packet Selectors. The document provides the basis for the definition of information models for configuring selection techniques in Metering Processes and for reporting the technique in use to a Collector.

RFC5476 - Packet Sampling (PSAMP) Protocol Specifications
This document specifies the export of packet information from a Packet SAMPling (PSAMP) Exporting Process to a PSAMP Collecting Process. For export of packet information, the IP Flow Information eXport (IPFIX) protocol is used, as both the IPFIX and PSAMP architecture match very well, and the means provided by the IPFIX protocol are sufficient. The document specifies in detail how the IPFIX protocol is used for PSAMP export of packet information. [STANDARDS-TRACK]
RFC5477 - Information Model for Packet Sampling Exports
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. [STANDARDS-TRACK]
