Multithreaded Multicasting

• Multicast messages stored in single buffer.
• One thread per participant in charge of communication.
• Connection-based communication (TCP):
  • Reliable but protocol overhead.
  • Notebook contents, inputs, and outputs.
• Connection-less communication (UDP):
  • Unreliable but efficient.
  • Sequence numbering scheme to detect package loss.
  • Control events.

Independent communication with each participant.
