1. Outline for rest of the course
   --> P2P and video streaming
   --> Datacenter networks
   --> Security
   --> Programmable networks
2. The stored-video streaming problem and how video is compressed and stored
   --> Intra frames
   --> Inter frames
   --> Periodic intra frames
3. Strawman designs for video streaming
   --> Blast everything at once and then watch
   --> Lowest quality video, one chunk at a time.
   --> Highest quality video, one chunk at a time.
   --> Highest quality video and then lowest quality video when you rebuffer
4. What users care about
   --> Startup delay
   --> Video quality
   --> Rebuffering
   --> Video quality variance
   (E.g., Netflix is much more worrried about rebuffering and average video quality,
   while YouTube is much more worried about startup delay.)
5. Differences from live-video streaming and video conferencing
   --> Live-video: video isn't fully available.
   --> Video-conferencing: much tighther time bounds are required.
