RFC 5474 Packet Selection and Reporting March 2009
Abstract
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.
