Data Packet Transmission in a LAN


I need your help:

I need to know how a data packet is transmitted from the sender to the receiver passing through the five Internet layers. Specially what device (hardware) the data packets have to pass through at each layer before reaching the destination in a LAN.

Thank you

Lamos

Check your textbooks and/or Google....if you need further help with your homework, try asking your teacher.

If this ISN'T a homework question, what version/distro of Linux are you using, and what are you trying to accomplish?

The first thing you need to do is to start distinguishing between the layers in your terminology. At the session layer an application data stream is split into packets, so packets are transmitted at L3 the "inter" networking layer.

L3 packets are transmission media agnostic so need to be placed into containers suitable to the Layer2 network they are being transmitted across. So typically an IP packet will get encapsulated into an Ethernet "frame", or a PPP "frame" or an FDDI "frame", or possible and ATM AAL5 "Frame". Obviously at L1 really the data only exists as "bits".

This is obviously simplified. (before some of the experts here start pointing out the exceptions and complications I've glossed over)

It may sound pedantic, but it helps you to start thinking in Layers, and if you can do that it will help you to model these processes in your head.
