Geez Jach, you are turning more into the Stockpuke you are every day. Perhaps you should stick to McWhorters. Nonetheless, you are wrong - again. First you're wrong that I posted that information about PNNI. All the posts you're giving me credit for came from John. You should check your sources before you post. All I said regarding this PNNI discussion was that you were having a technical discussion with the wrong guy - John C.. But if I must - you are wrong about PNNI. You should go back and read the early versions of the specification (specifically af-pnni-0026.000 and af-pnni-0055.000). In this document they discuss the PNNI mechanisms checking "routing tables" in each switch. from pg 13 of af-pnni-0026.000 At each hop along the path to the destination switching system, the call setup procedure consults the intermediate switching system's routing table. The destination address is compared to the routing table entries using the length (number of significant bits) stored with the entry. An entry in the routing table matches the destination address when N bits of the two addresses are equivalent where N is the number of significant bits. From Page 1 of af-pnni-0055.000 PNNI topology and routing is based on the well-known link-state routing technique. You see Stockpuke, in order to understand PNNI you first need to understand the reason PNNI is used and the underlying function it performs. You may want to go back and read up on this. So, Johns position that the underlying fabric (and for that matter the thought process) behind PNNI is indeed routing is accurate. They both determine paths through the network (and do not move traffic). Now, I will say that an ATM network is much more static relative to paths. Now, can we move on and talk about CSCO and next weeks earnings report. OG
