- - - - User Datagram Protocol (UDP)
        
        Best-effort protocol
        
        Usage: video conferencing, gaming, streaming
      - Transmission Control Protocol (TCP)
        
        Reliable protocol which establishes a connection between two hosts
        
        Usage: File transfer, email, web browsing
  - - - IP addressing using IPv4 and IPv6
      - Routing
    - - Connetionless
      - Best-efford
      - Medium independent
    - - DF (do not fragment)
      - MF (more to follow bit)
      - Fragment Offset
      - Packet is reassembled at final destination
  - - - Propagation delay
      - Transmission delay
      - One-way delay/latency = P(delay) + T(delay)
    - - Corrupted during transmission
      - Congestion losses in routers
