Protocols & Standards • OSI Model • Layers • Protocol Stacks • FedEx Analogy
This course begins the “IP courses” in the Certified Telecommunications Network Specialist (CTNS) certification package.
The OSI 7-Layer Reference Model is used to sort out the many functions that need to be performed, to be able to discuss separate issues separately. The functions are organized into groups called layers, which are stacked one on top of the other. This allows us to relate different pieces of the puzzle in subsequent lessons.
The course starts with the big picture, then one lesson for each layer, then protocol stacks.
