How packets travel over network by using Layer 2 and 3 information. This is a class-based course about Networking. In this session we were discussing how packets travel on the network using layer 2 (data link) and layer 3 (network) information.

We decided to explain the concept using simulation, asking a volunteer from students  to become a packet that travels over network. On his front, we put “headers” information (layer 2 and 3) so router can use that information to forward the packet to destination.
