There has been some interest in discussing the problems associated with interconnecting Token Rings and Ethernets. This problem arises because of the differing bit transmission orders that exist for these media. Note that this also a problem for FDDI/Ethernet. This has ramifications on both routable protocols and bridging. I will be hosting a BOF to discuss this problem and possible solutions at the upcoming Interop. I'd like to get some idea of how much interest there is in people attending. If you are planning on coming could you please email me your name, email address, and a brief description of your interest. Or just send me you name/email address if you are too busy. Here is a brief description of the BOF: BOF Title: Token Ring/Ethernet bit ordering Addressing Issues Description: Token Ring and FDDI transmit high order bit first while Ethernet/802.3 hardware transmit low order bit first. This coupled with the common addressing space causes significant problems when these diverse mediums are interconnected. This is especially true for bridging. The purpose of this BOF is to discuss this problem, present several potential solutions, and to explore additional solutions. Time and Place: Interop '89, Thursday Oct 5, 6-8pm, C-4 * This time and place are tentative and subject to change. Be sure to check the current schedule when it is published. thanks, -c cire|eric Eric B.

Eric, A possible conflict with your proposed BOF is the IP over FDDI BOF to discuss RFC1103 that will happen Thursday night from 5-8pm. Contact is Monica Hart (mhart@nri.reston.va.us). Bob Fink

I am now aware of two other BOFs that are at the same time. With such a wealth of things to talk about that is bound to happen. There have been quite a few people that have already said they would come to the Token Ring Addressing BOF and Thursday at 6 is really the best time for my participation. So Thursday at 6 it is. Here are the other ones that I know about: Token Ring-FDDI/Ethernet Interoperability Addressing Issues (mine) FDDI MIB IP over FDDI. Discussion of RFC 1103. Is there really things to discuss here? I thought that there would be an 802.2 header and there you go. (SNAP, etc.) -c cisco engineering

There is significant overlap between the FDDI and the TR stuff, especially with regard to transparent bridging. FDDI is in much better shape because it doesn't have an installed customer base. I will have to be at the FDDI BOF, given that I wrote 1103.

Well this is getting weird. I just checked with the Interop BOF coordinator and there isn't a IP over FDDI BOF scheduled at all let alone at Thursday 6-8. There is one on FDDI management with is the FDDI MIB one. I checked for the entire week and there isn't anything at all close to describing it. Now there are several options here and I think we should organize them to maximize our coverage. There has been significant interest (yes I know actual attendence remains to be seen) in the TR-FDDI/Ethernet addressing BOF. There is also significant interest in the IP over FDDI and other issues BOF. I'd like to see us arrange things so that these sessions don't overlap too badly. One option is back to back but perhaps that is too brutal especially for the east coast types. We could also say have one on Tuesday from 6-8 and the other one on Thursday. Right now I still have Thursday 6-8 but I'm certainly willing to work with the community on this. Either way we need to do this soon. Today would be ideal. Thoughts, -c

Phill Gross has tentatively scheduled an IP over FDDI BOF for Thursday from 5 to 8. I have my doubts about being able to do much on Tuesday myself, because I'll likely be setting up for demos that start Wednesday. By Thursday us EDTers should be fully acclimated...

How about if we do this... IP over FDDI BOF... 5-7+ TR-FDDI/Ethernet Issues 7-9+ Those that want to go to both (I do) bug out at 7 after two hours. Obviously it is important to stay focused. I know I'd like to sit in on the IP over FDDI too. What is Phil's address? Could you also pass this on to him Dave? -c

I just called Phil at (703)620-8990. He won't be in till later today; I left a message to read the tcp-ip list. Regards - Craig

Will you write up a summary of the discussions and post it here? I won't be going but am very interested in what comes out of all this. Dave Sheehy (916) 785-4012
