To see how these topics have changed since the course has taken a greater focus on the application later, compare this version of the topic level learning goals to the ones in revision 1.3. 

   1 The two parts of networking
      * the technology that actually exchanges data
      * the rules/semantics (protocol) for the data exchange 
   1 Explain what the network fallacies are/mean:
      * (network reliability, latency is zero, infinite bandwidth ...)
   1 Organization, at a very high level, of the end systems + routers + communications links
   1 Organization role of protocols, network of networks, standards
   1 Network of networks
      * layering, tiering 
   1 Protocol properties, reliable delivery, ordering, best effort
   1 Properties of networks, delay, bandwidth, errors, throughput
   1 Sharing of bandwidth
   1 (Maybe) Case for packet switching
   1 What contributes to delay, including queuing delay
   1 Interpreting traceroute with respect to delay meanings
   1 idea and purpose of protocol layering
   1 basic network security/vulnerability issues (trojans, man in the middle etc)
   1 Application level protocol examples & how information is exchanged
      * web/http as a bi-directional connected streams, client server model
      * ftp - difference between a control channel and out of band data channel
      * mail protocols - fact that there is no guarantee of who is sending mail
      * DNS - large distributed application - not based on connections - how it works
      * P2P example (bittorrent - edonkey, DHT)
   1 Addressing - role of IP address and port
   1 Effect of different latency, throughput, loss etc on application designs
   1 Performance HTTP as an example of ways to make things go faster
   1 multiplexing and demultiplexing and how it is used - perhaps http server and handling multiple requests at the same time can be used to illustrate this in some way.
   1 creating a reliable data stream from an unreliable one
      * dealing with lost/corrupt data
      * maintaining order, if needed
      * timeouts, ACKS, NACKS, etc
      * sequence numbers
   1 Performance with respect to retransmission scenarios - sliding windows, selective ACK, go back N, sequence numbers
   1 Event response diagrams for reliable protocol 
   1 Estimating round trip time and using it to set timeout values
   1 Connection setup
   1 Connection termination
   1 Congestion what it is and how it occurs
   1 Performance issues of congestion
   1 IP addresses, subnetting, and CIDR
   1 DHCP - what it does, why it is useful
   1 IP address assignment from ICANN
   1 How NAT works - issues and problems
   1 Why NAT is used
   1 Where can errors during transmission occur and how are they detected - checksums, CRC end-to-end arguments
   1 Sharing of a channel (Bandwidth)
