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.
