NTP improvements for wallclock: 1 (8273368593000) Separate Wire Protocol from Algorithms. It has been shown that filter algorithms other than PLL’s can archive the same result as NTPv4’s PLL does in 60 minutes rather than 1 day We do not want to change the wire format at this point. Installed base Need a way to gain more experience and solve some short term issues In NTPv4 messsage typecode 7 is not used. Use it for a TLV encoded extention. (There is also the 4 upper bits in stratum...) Add a 128 bit timestamp that is MJD + 64 bit fraction of day Add a timestamp that is linear time (GPS?, TAI?, NTP-unique?) Add a way to querry a server about status, keys etc Add a way to quesrry server about actual timesoure and charcteristics of transfer Add a way to do secure transfers client-server-client Reach out to IEEE/802.* and ask that they make the timestamping mechanisms used by IEEE1588 generic. So timestamps is an Ethernet function for anyone who wants to use it. Possible improvements to NTP? |
