CMPS 161: Networking and Security
Besides routers, another very important device is a switch. In essence, whereas a router connects networks, a switch makes the networks themselves possible. Switches have largely replaced hubs, which could be considered unintelligent switches. An important concept for switches are Virtual Local Area Networks (VLANs), because with this technology it is possible to dynamically define LANs without physically rewiring cables. In addition, we will look at how routers perform routing. As you can imagine, sending a packet from one continent to another is no trivial task and requires sophisticated algorithms. This is especially true if you take into account that the internet has to be robust against failures.
