The OSI Reference Model
I'm always a bit amazed at the attention conversation about the OSI reference model generates. For me, being a teaching foundation in telecom technologies, it was ingrained in every course I taught. It really didn't matter if it was ATM, frame relay, routing, LANs...everywhere I taught, the OSI model played a key role.
A while back I posted a description and overview of the OSI reference model here. Frankly, I was amazed to find it a week later popping up in college course syllabus materials. Rather than write about it again, I thought this time around I'd share this podcast from my friends.
PodSnacks: The OSI Reference Model
Sometimes, getting back to the basics is a good idea. Today's PodSnack provides a high-level overview of the OSI Reference Model
and the function of its seven layers. The OSI-RM dates back to the mid
1970s, and many aspects of it have altered somewhat since that time. It
remains, however, a basic language for talking about networking.
Throughout the industry, references to Layer 1, Layer 2, and Layer 3
technologies and services abound. Even the concept of layering comes
from the Reference Model.And you get brownie points if you can identify the kind of bird heard in the background!
