SNA: why tokenring?

2000-10-12 Thread Alldread AK2 Robert J
I am just curious as to why SNA still runs on tokenring today. Is there any reason that it cannot just hook right into an ethernet network?? I have read a few white papers on SNA, and I assume that because tokenring was the major LAN media back in the day, and because SNA uses RIF's to

Not to shift the subject, but if you need the consistent latency and reliability for multimedia, why not go with ATM? The bandwidth available is better than Token ring and the cost isn't *that* much more. In any case, SNA over Ethernet is no problem in a well-designed network. As Priscilla

You are not really going to get the full benefits of going ATM to the desktop until the Apps running on the client are ATM aware. Running LANE or doing 1483 is still not going to give you a good COS as you would be using AAL5 anyway, which is UBR. Some VTC ( Video Teleconferencing ) vendors
