[16:12:24] <cabo> Thomas: Page 40/41
[16:13:11] <cabo> (“Virtual reassembly buffers”)
[16:14:38] <cabo> One project could be to write this up for mortals
[16:14:39] <Thomas Watteyne> I assume you mean "6LoWPAN: The Wireless Embedded Internet"
[16:14:44] <cabo> Yes.
[16:14:45] <Thomas Watteyne> I assume you mean "6LoWPAN: The Wireless Embedded Internet"?
[16:15:10] <Thomas Watteyne> I don't have it in front of me, but remember the tag needed to be global, not local?
[16:15:46] <cabo> Yes, needing to attach the tag to the source address is a limitation not discussed in the book
[16:15:53] <Ines Robles> Suresh Krishnan speaking
[16:15:53] <cabo> That does not help with multi-track forwarding
[16:16:30] <Thomas Watteyne> I have the book open now, which section? 2.5.2?
[16:16:35] <cabo> Yes
[16:17:23] <Ines Robles> Gabriel Montenegro speaking
[16:18:48] Benjamin Damm leaves the room
[16:18:58] Eunice Pascua joins the room
[16:19:22] <Ines Robles> 4 have read the draft
[16:19:33] <jch> What's the maximum data rate that 6lo is expected to support?  I don't see anything in the charter.
[16:19:52] <Thomas Watteyne> I read the sentence "[...] implementations may be able to optrimize this process by keeping virtual reassmble buffers [...]". I think that's the key sentence. The problem I see is, as discussed at the mic, what happens when 2 ancestors in the routing structure pick the same tag, and a couple of hops further, the two flows of fragments meet a a single node. That node will not be able to distinguish one fragment stream from another.
[16:19:54] <cabo> We chose parameters appropriate for the 250 kbit/s of 15.4
[16:20:06] <cabo> Carles’ approach is really for smaller data rates
[16:20:17] <jch> ty
[16:20:35] <cabo> The tags have to be combined with the IP source.
[16:21:07] <cabo> The tacit assumption is that all fragments from one packet from an IP source are fragmented at the same node which will assign unique tags
[16:22:25] <cabo> A recommendation to choose random tags may help a bit, but you run into birthday problems quickly
[16:24:18] <Thomas Watteyne> the IP source only is included in the first fragment, in subsequent ones, the IP source is not present. Do you mean the tag needs to be chosen in such a way that each node uses a different tag range, for example by using its [802.15.4 short address | counter] as a tag?
[16:24:29] <Thomas Watteyne> we need a whiteboard
[16:24:37] <cabo> Indeed.
[16:26:29] <cabo> I misspoke, this needs to be L2 source (which is the one that chooses the tag)
[16:27:07] <jch> What's data concatenatin?
[16:27:26] <cabo> No idea; aggregation of multiple packets into one?
[16:29:59] rdroms joins the room
[16:30:00] Benjamin Damm joins the room
[16:30:09] <tomherbst> as I recall (2 years+ since I was in the group) it’s multiple IE’s in a packet
[16:31:05] <jch> An IE is what we call payload?
[16:31:22] <tomherbst> information element - different payload types and other messages
[16:31:30] <jch> ty
