Video: Getting a Packet Across a Network
After (hopefully) agreeing on what routing, bridging, and switching are, let’s focus on the first important topic in this area: how do we get a packet across the network? Yet again, there are three fundamentally different technologies:
- Source node knows the full path (source routing)
- Source node opened a path (virtual circuit) to the destination node and uses that path to send traffic
- The network performs hop-by-hop destination-address-based packet forwarding.
