I haven't seen it in a live network and was wondering if I had missed out on seeing it used ? </p> http://etherealmind.com/forum/topic/4#post-15 Sat, 30 Aug 2008 15:21:55 +0000 cciepursuit 15@http://etherealmind.com/forum/ <p>LOL. Perfect! </p> http://etherealmind.com/forum/topic/5#post-14 Sat, 30 Aug 2008 14:57:54 +0000 PacketU 14@http://etherealmind.com/forum/ <p>The OSI is a great model, but I think that there must be some flexibility in interpretation. I don’t necessarily agree with some others interpretation of it. I look at it like this. On the sending side data flows down the osi. On the receiving side it flows up the osi. At intermediary hops, it may flow up and down the bottom 3 layers (at a router), or the bottom two layers (at a switch), or at any other point (at a proxy or protocol gateway). </p> <p>Many books and posts classify HTTP and SMTP at the application layer. I disagree with this. Like RPC, these are session layer. If you look at the exchange on a wire, it the HTTP or SMTP commands begin following the Transport Headers information and are typically identified by the TCP or UDP port. They issue the flow control for commands that influence the transmission of raw ASCII or HTML. ASCII and HTML are presentation layer protocols. Documentation also classifies Traceroute and FTP as application protocols. Traceroute I would probably agree with, and ftp I agree with when you consider the FTP application. The FTP protocol itself (PUT, LIST, PASV, PORT etc), I consider session layer. </p> <p>I know these will likely not be the correct answer on some tests, but this is the way that I view and understood them. When you use a protocol analyzer regularly, you quickly realize this stuff is sort of like peeling the layers off an onion. Assuming that I am just totally incorrect in my interpretation of the OSI, I would still say that’s okay since I am successful with troubleshooting and deployment of this view. OSI is simply a model to help us visually understand how systems communicate. Many disagree with me on this. I am curious as to the thoughts of others. </p> http://etherealmind.com/forum/topic/5#post-12 Sat, 30 Aug 2008 11:11:03 +0000 Greg Ferro 12@http://etherealmind.com/forum/ <p>Feel free to post here if you want to debate a topic, either something that is in my blog or a new topic.

It integrates with your overall site design perfectly.</p> <p>Do you have a suggestion for a word that describes people (mostly management but sometimes IT staff) who know what an abreviation or acronym stands for - and nothing else:</p> <p>"So we might need to implement SIP."<br /> "Ah yes, SIP. Session Initiation Protocol." &lt;nods knowingly&gt;<br /> "Ummm...yeah. Do you know what SIP does?"<br /> "It 's a protocol that initiates the session."<br /> &lt;head explodes&gt;</p> <p>This bugs me because I often forget what the abreviation actually stands for but I know how that technology works. I can break down DSCP to the bit level and explain why one binary number is significantly different than another, but I get tripped up by someone asking me what DSCP stands for and then rolling their eyes when I can't remember that DSCP stands for Differentiated Services Code Point.
