Title : Network Time Protocol Last Extension Field
Author : Harlan Stenn
Filename : draft-stenn-ntp-last-extension-00.txt
Pages : 4

Abstract:
NTPv4 is defined by RFC 5905 [RFC5905], and it and earlier versions
of the NTP Protocol have supported symmetric private key MAC
authentication. MACs pre-date the Extension Fields introduced in RFC
5905 [RFC5905], and as the number of Extension Fields grows there is
an increasing chance of ambiguity when deciding if the "next" set of
data is an Extension Field or a MAC. This proposal defines a new
Extension Field which is used to signifiy that it is the last
Extension Field in the packet. If present, any subsequent data
SHOULD be considered to be a legacy MAC.
