Yes. (And if you were asking Howard, the answer is emphatically YES ;-) >Do you remember LU and PU and logic >controllers?? Yes. >Do they all work the same as IP networks or VOIP and IP >telephony networks? Yes, pretty much. Networking 30, 20, 10 years ago dealt with the same stuff we're still dealing with today: layers cables wireless (not as much as there is now, but definitely some) circuits (both virtual and real) connectionless versus connection-oriented reliability versus low overhead connection establishment and teardown flow control windowing packetization signaling error detection error correction ACKs and NACKs and WAKs (WAKs kind of fell out of favor) dynamic and static addressing dynamic and static routing pesky users security (although the old-timers should have done better with this ;-) network management transferring files and other data database lookups You get the picture. >Do you know all the traffic in your data network???

They could be phased in carefully instead. With good design, testing, troubleshooting methodology, I would be OK with this. >Last but >certainly not least, how many mainframe guys know IP networking.

I really struggled with voice at first due to a lack of PBX, telephony knowledge, but I did OK finally, got my CVOICE cert whoopee.) >Answer is very few.

Lab rats do deserve respect, if that's your point. To get a CCIE is extremely difficult, whether you did it with experience or not. Gotta run.
