Flow Aggregation for the IP Flow Information Export (IPFIX) Protocol
This document provides a common implementation-independent basis for the interoperable application of the IP Flow Information Export (IPFIX) protocol to the handling of Aggregated Flows, which are IPFIX Flows representing packets from multiple Original Flows sharing some set of common properties. It does this through a detailed terminology and a descriptive Intermediate Aggregation Process archite…
The Intermediate Flow Selection Process is the process of selecting a subset of Flows from all observed Flows. The Intermediate Flow Selection Process may be located at an IP Flow Information Export (IPFIX) Exporter or Collector, or within an IPFIX Mediator. It reduces the effort of post-processing Flow data and transferring Flow Records. This document describes motivations for using the Intermedi…

This document proposes an additional endpoint for OAuth authorization servers, which allows clients to notify the authorization server that a previously obtained refresh or access token is no longer needed. This allows the authorization server to clean up security credentials. A revocation request will invalidate the actual token and, if applicable, other tokens based on the same authorization gra…

Message Header Field for Indicating Message Authentication Status
This document specifies a message header field called Authentication- Results for use with electronic mail messages to indicate the results of message authentication efforts. Any receiver-side software, such as mail filters or Mail User Agents (MUAs), can use this header field to relay that information in a convenient and meaningful way to users or to make sorting and filtering decisions.
A Mechanism to Measure the Routing Metrics along a Point-to-Point Route in a Low-Power and Lossy Network
This document specifies a mechanism that enables a Routing Protocol for Low-power and Lossy Networks (RPL) router to measure the aggregated values of given routing metrics along an existing route towards another RPL router, thereby allowing the router to decide if it wants to initiate the discovery of a better route.
Reactive Discovery of Point-to-Point Routes in Low-Power and Lossy Networks
This document specifies a point-to-point route discovery mechanism, complementary to the Routing Protocol for Low-power and Lossy Networks (RPL) core functionality. This mechanism allows an IPv6 router to discover "on demand" routes to one or more IPv6 routers in a Low-power and Lossy Network (LLN) such that the discovered routes meet specified metrics constraints.
Autonomous System (AS) Reservation for Private Use
This document describes the reservation of Autonomous System Numbers (ASNs) that are for Private Use only, known as Private Use ASNs, and provides operational guidance on their use. This document enlarges the total space available for Private Use ASNs by documenting the reservation of a second, larger range and updates RFC 1930 by replacing Section 10 of that document.
This document describes how the experimental TCP option codepoints can concurrently support multiple TCP extensions, even within the same connection, using a new IANA TCP experiment identifier. This approach is robust to experiments that are not registered and to those that do not use this sharing mechanism. It is recommended for all new TCP options that use these codepoints.

IMIX Genome: Specification of Variable Packet Sizes for Additional Testing
Benchmarking methodologies have always relied on test conditions with constant packet sizes, with the goal of understanding what network device capability has been tested. Tests with a constant packet size reveal device capabilities but differ significantly from the conditions encountered in operational deployment, so additional tests are sometimes conducted with a mixture of packet sizes, or "IMI…
