<p class="MsoNormal">So we’re working the revisions to the LTP spec, and one thing we’d like to do is to have a ‘field length identifer’ that serves (at least logically) as the index into a lookup table that gives the lengths of a number of LTP header fields.
So, for example field Length Identifier 1 could mean:<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We believe that the ‘lookup table’ should be a SANA registry (we’re currently envisioning maybe a couple of ‘profiles’ e.g. for low- medium- and high-rate links).<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I THINK we want to write the spec in such a way that we talk about the field length identifier and then say something like: “For field lengths determined by the field length identifier, implementations MUST use the field length values from
<insert SANA registry here>”.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Does this seem reasonable? Other thoughts / suggestions?<u></u><u></u></p>
