We will take a bottom-up approach. In your 152A, you have learned about basic principles of networking, and lower layer of the protocol stack. For example, you have learned about the physical layer and the data link layer. How does the ethernet work, encoding, framing, error correction, circuuit switching, packet switching, etc. Now, it is time for upper layer protocols. The more CS flavored works.
