This is the protocol set of choice of the UK academic network advisory group (JNT). They chose this stack because it will make inter-networking easier (because there are NO long-haul IP networks over here ONLY X25). There are implementations on several other systems (e.g. VMS and CMS) and other products like Ethernet pads and gateways. So far there don't seem to be any problems. I would say that X25 and TCP are about equally complicated. I can give you more details if you ask specific questions. Adam Hamilton

AT&T's STARLAN release 3.0 is using ISO protocols. The ISO Level 4 protocol over IEEE802.3. (I don't have the ISnnnn number of the protocols handy, they have adopted the IEEE802 family of protocols as an implementation of layers 1..3, I believe). It is actually faster than the protocol previously used (our own, called URP -- Universal Receiver Protocol) but that may just be a better implementation, rather than any major improvement in the protocols themselves.
