<p class="MsoNormal"><span style="font-size:11.0pt">OK, I’ve uploaded all the PIDs to the “CESG Review 1 20221000” folder. There are the RID-formatted ones from SLS and the document markup from Peter (in the .docx document). In the document I inserted Peter’s
comments as comments and replied to most of them. I think there are a couple large topics listed below (though I invite folks to correct that assessment). As a way to address some of these I added some text to the end of section 2 talking about ongoing /
future work; many of Peter’s comments dealt with things like “how do I know the source EID of this bundle isn’t spoofed”? I think the way we’ve thought of to address that is BPsec, so there’s a little bit of text there about BPsec and network management.
Have a look, comment at will.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">1) What information needs to be in a node / EID registry? e.g. should it contain information about the convergence layers a node supports or other (detailed) configuration information? What if those convergence

<p class="MsoNormal"><span style="font-size:11.0pt">If implements standardized network management, which ADMs?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Lit of Convergence Layer Adaptors supported<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">---- <I think the following are 'too much' for the 'node number' registry -- Maybe we define some sort of separate 'ops' registry for highly-dynamic information?> ------<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">2b) For the moment, until we (SIS-DTN and SEA-SEC) work out something better, the key management solution (both for configuring keys / key management and exchanging keymat so as to identify peers) is going
to be 'manual'.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">3) It might be worth adding a subsection to the end of section 2 that discusses ongoing / future work. Such a subsection could talk about BPsec and a bit about how we envision its use to support authentication
/ identity, and network management including the types of information we expect to be managed by some of the basic ADMs.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">How MUCH do we need to discuss security (and potential security policies) there? We have a BPsec Red Book and a Green Book in the current charter.<o:p></o:p></span></p>
