I am assuming that the blue changes are the ones applicable to this revision. Point 2 appears to be redundant (but more clearly stated) than point 5. But I...
during my tests, I have seen NAT routers do both. The BAC0 port being retained outside the NAT box does occur, usually. In my case, if there is also a static...
Dear IP-WG Attached is RL-002-4. I've modified a bit of wording throughout and have added points 4 and 8 from RL-002-DM-1 to the NAT configuration items. ...
Dean IP-WG I see your point from 6.5.3. However, as far as establishing address of BACnet router is concerned, one should note that the "Who-Is/I-Am" method...
Dear IP-WG: Ok, I have implemented RL-002-4 as described, and there is still a subtle problem. It is not a specific problem with this iteration of RL-002, it...
All, I am a little confused by the description of the BBMD & Bacnet-IP device. Are they part of the same hardware? Is 102.168.20.100:47801 the address of the...
Hi Buddy, I understood the device to be part of the BBMD, and residing on the global BACnet network that the FD joins, otherwise we would not have this problem...
Hi Roland, I was thinking along the same lines as you are then I realized that there is a subtle interaction here that may mean that this would not work EVEN...
Roland, Regarding your last point, I totally agree that this could solve the problem. However, from what I've heard, there is currently a push to require a...
I finally have my thoughts together on this, and I think the situation gets ugly for a couple reasons ... First, how common is source address verification on...
Exactly. It does get ugly around certain issues. RL-002 handles this mostly by making it so that it doesn't matter what the "previous hop" MAC address is,...
Bill, RL-001-4 is the latest revision of the IP Functionality Tests. This proposal was voted to be submitted to the SSPC by the IP-WG in Chicago. Please add it...
Btw. I realize this may be a little off topic, but since we have been dealing with router path updates issues I thought this was somewhat relevant. Section...
Dean, I put my comments in the body of your email. Roland _____ From: bacnet-ip-wg@yahoogroups.com [mailto:bacnet-ip-wg@yahoogroups.com] On Behalf Of Buddy...
Roland, I think you put your comments in the bottom of my email. I hope Dean doesn't take it as an insult that you mistook my writing for his. :-) I take it a...
In the NAT discussion, we've touched on the topic of whether or not I-Am's should be globally broadcast, locally broadcast, or unicast. I have a task before me...
Roland, Yes, I have seen the source port just pass through without change, as you are seeing. However, at some point, the router will start mapping the source...
I just want to re-iterate that with the addition of a "NAT-Unicast" message with the same format at the "Forwarded-NPDU", RL-002 becomes extremely robust...
... Who-Has and I-Have can also be considered a kind of "distributed directory service". ... With a fairly large network like ours at Cornell I don't want any ...
... Better yet...and I can't believe I didn't mention this in the last message...take a good look at Zerconf [1], I think there are some real opportunities...
Joel, When someone mentioned Zeroconf at a recent BACnet committee meeting, Dave Robin said (I am paraphrasing) that business systems do not use that...
- the where-is-device services should accept a list-of-devices, or a device-range and the here-is-device service should allow indication of a list of devices. ...
ZeroConf is great for small infrastructure-less environments. Small businesses may choose to use ZeroConf to set up a handful of PC's with it. Apple is...
No further comments on this? We are going forward with a proprietary version of RL-002 with the change I have suggested below, and it is working wonderfully. ...
I think we will discuss this at Germantown. My thinking is the case where this is a problem is a small exception to the rule and the better way to address it...
