I've finished the driver for IP over the ARCnet interfaces made by Pure Data Inc. and Standard Microsystems Corp. If I can get an ethernet forwarder up, I will demo it in D.C. this week. As per a few requests, it supports ARP, though it really doesn't seem necessary. One of the changes I had to make to PCIP was to include fragmentation/reassembly support, following RFC-815. I don't know if I can call it lightening fast, but it gets you past the ARCnet 508 byte MTU. Since it is at the IP level, it will (of course) be useable with other network interfaces. With any luck, it will be in the next release of PC/IP. If you would like to test drive it before then, contact me by e-mail. My thanks to all the people who contributed their thoughts about the hows and wherefores, as well as the equipment loans. An RFC from all this should hopefully be forthcoming, as soon as I can get a router up so I can collect some useful timing statistics... -Philip

Philip, as our localnet talks to the Internet via SATNET which has a maximum packet size of 256, almost every packet gets fragmented unless. With CMU PC/IP we are currently using, at least with telnet, the trick of defining a small window (216 bytes counting the tcp-ip overhead). The obtained perfomance is very low, and we cannot use tftp. We are certainly interested in testing your fragmentation/reassembly code to see the improvement. A.

Good day, Could somebody tell me how to obtain CMU pc/ip? I don't have ftp access to the Internet - Can I get it from a Bitnet file server? Do I have to have a license from CMU first?
