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.

More details in the Getting Packets Across the Network video.

The video is part of How Networks Really Work webinar and available with Free ipSpace.net Subscription.
