The other day we talked about local area networks (LAN), and that brought to mind a little protocol we often find in LANs where we have multiple switches arranged in a redundant configuration. We call it the Spanning Tree Protocol (STP) , or more recently Read More...

Time for another snack. Peter (and a few other instructors) have given me a set of audio clips that all have to do with the Point-to-Point Protocol (PPP). This is the Data Link Layer (Layer 2) protocol used on every dial-up Internet connection. It is Read More...

And now for something completely different, sort of. In recent days we've wandered from the Physical Layer to the Application Layer , so I thought we'd wander back down the stack for a brief visit at the Data Link Layer . Specifically, I thought Read More...
