Technical Summary 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 IPFIX protocol, this information model is an extension to the IPFIX information model. Working Group Summary There is consensus in the WG to publish these documents. Document Quality Several of the Information Elements defined in this document have already been implemented by academic as well as industrial institutions, but not all of them have been implemented and tested, yet. Personnel Juergen Quittek is shepherding this document. Dan Romascanu is the responsible Area director. Juergen Quittek will be the principal expert for the selectorAlgorithm registry working with IANA. RFC Editor Note 1. Insert in section 1, after the second paragraph the following paragraph: NEW: Although the PSAMP charter specified no requirements for measuring packet errors (such as drops, malformed, etc.), and this draft does not cover such data, if there is need for collecting and exporting packet error information, the appropriate Information Elements can be requested from IANA, and exported with the PSAMP protocol. 2. in Section 8.2.4. samplingTimeInterval OLD: Abstract Data Type: dateTimeMicroseconds NEW: Abstract Data Type: unsigned32 3. in Section 8.2.5. samplingTimeSpace OLD: Abstract Data Type: dateTimeMicroseconds NEW: Abstract Data Type: unsigned32 4. in section 8.5.1. ipHeaderPacketSection Delete: Data Type Semantics: quantity 5. in section 8.5.2. ipPayloadPacketSection Delete: Data Type Semantics: quantity 6. in section 8.5.3. mplsLabelStackSection Delete: Data Type Semantics: quantity 7. in section 8.5.4. mplsPayloadPacketSection Delete: Data Type Semantics: quantity 8. in Appendix A.: Delete: Using XML-based specifications does not currently address possible IANA implications associated with XML Namespace URIs. The use of Namespaces as an extension mechanism implies that an IANA registered Namespace URI should be available and that directory names below this base URI be assigned for relevant IETF specifications. The authors are not aware of this mechanism today.
