Network Layer
Nodes, Links, and Graphs
Addressing
If you pass the message, how does the next device know the
destination of the message?
Message passing
Full vs Partial knowledge
Internet Protocol (IP)
Wireless Mesh Network
Fully wireless networks also use routing concepts.
Small conversations can occur simultaneously with minimal
interference!

Transport Layer
Maximum Transmit Unit (MTU)
Packets have a maximum size limit.
Destination node often needs to know how many packets to expect.
Transport Layer also handles ordering of packets.
Handshaking
