Anyone have any idea what is required to hack multiple connection capability into CMU PCIP? I have been toying with idea... The most immediate problem I can see is lack of buffers unless you start using far pointers. But does anyone really need a (say...) 4k window? -Philip

Maybe 25% of the TCP you have is usable. The ring buffer *has* to go, but the single fixed transmit buffer can stay, unless you want it to go fast. Keep in mind that what you have was designed for Telnet, and does not work particularly well in even LPR, which sends much more data that it receives. You need a 4K window if you want to get good speed out of high-quality network interfaces. Single-buffered interfaces like the 3C501 actually benefit from a smaller window (1 packet worth). jbvb
