Things I have done research on and will post notes as soon as I can:

  • Buffers and connections and how they consume memory.
  • Analysing network errors and retransmissions
  • Device interrupts and loading
  • TCP window size, maximum segment size (MSS) and global file transfers particularly FTP. Why it takes so long to transfer a file across a WAN or global connections.
  • Bad network topology how to analyze. LAN vs WAN vs Internet (global) connections.
  • Google's Linux Kernel TCP BBR implementation: http://everythingsysadmin.com/2017/07/googles-bbr.html
