Thank you for your insightful comments. I would like to be enlightened on exactly how a proposed migration from RFC1490 to RFC1483/1577 will occur. As I understand it, there needs to be a translation method between NLPID and LLC/SNAP. There seem to be other locations in the stack where translation must occur. Is there capability today or even planned that will do these translations? [...]
I would migrate, rather than translate. Depending on the Cisco 7000 HSSI and/or AIP microcode, an ATM NAP could migrate a PVC at a time or the whole NAP at once. I assume that this migration will occur before NAPs become very large. [By the way, translation between RFC 1490 (NLPID) and RFC 1577 (LLN/SNAP) is still an issue for frame relay interworking units, even if it isn't required for 1490-1577 migration in an ATM-only NAP.] -tjs
