Question
Chapter 4.4, Problem 3QE
Program Plan Intro
Transport layer:
Transport layer divides a message into manageable segments so that the segment can be reassembled at the message’s destination, these segments are known as packets, and the transport layer hands the packet to the network layer.
Network layer:
The network layer determines the next intermediate destination of a message segment with the use of the forwarding table. It determines where to send the packet to get it started. The network layer returns the packet to the link layer for actual transmission.
