The IESG has received a request from the Mobile Ad-hoc Networks WG (manet) to consider the following document: - 'Rules for Designing Protocols Using the RFC 5444 Generalized Packet/ Message Format' <draft-ietf-manet-rfc5444-usage-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-06-29. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract RFC 5444 specifies a generalized MANET packet/message format and describes an intended use for multiplexed MANET routing protocol messages that is mandated to use on the port/protocol specified by RFC 5498. This document updates RFC 5444 by providing rules and recommendations for how the multiplexer operates and how protocols can use the packet/message format. In particular, the mandatory rules prohibit a number of uses that have been suggested in various proposals, and which would have led to interoperability problems, to the impediment of protocol extension development, and to an inability to use optional generic parsers.
