Harmonization IEEE WAVE (WSMP/WSA) with ISO FAST (FNTP/FSAP)

15. August 2013

WAVE ISO TC204 WG16

At the meeting of IEEE WG1609 (WAVE) in Annapolis the harmonization of IEEE WAVE (WAVE short message protocol / WAVE service advertisement) with ISO FAST (Fast networking & transport layer protocol / Fast service advertisement protocol) was further discussed with representatives from ISO TC204 WG16.

Based on the recommendation from the EU/US Harmonization Task Group HTG 1 & 3 it is favorable to fully harmonize such that for the 802.11 access technology both protocol sets are identical. This requires that IEEE accepts as a minimum the concept of port numbers, and ISO accepts several issues, e.g. the security specification, the IP router advertisement, and 802.11-specific features.

An optimum way forward is that both SDOs continue to maintain their standards, but establish suitable cross-references. Whilst the WAVE approach is specifying a whole system dedicated to the 802.11 access technology, the ISO approach is specifying protocols to be executed in an ITS station in support of any kind of suitable access technology. Consequently, the station-internal management of the two approaches will remain differently.
