OSI, per se, doesn't help anyone do anything. But it provides a framework, so that when you're discussing some problem with another engineer/architect/PM and they say "why don't we do 'x'?" you can draw up something quick and say: "the problem is here:
+- | <- what you are talking about +- | +- | <-problem is here +- This can help when architecting an encryption solution, or when you're troubleshooting some network issue. It provides a hierarchy of requirements (upper levels are not going to work if something lower in the stack isn't).

The OSI model *is* irrelevant, because it's incorrect. Teh interwebs (and everything else) don't conform to it. The 4 layer TCP/IP model is closer to reality, though still not completely accurate. http://en.wikipedia.org/wiki/TCP/IP_model Kurt ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
