Multicasting

• How to implement one to many communication in interceptor?
  • Multicast must be reliable (inconsistencies otherwise).
  • Must tolerate slow connections to some participants.
  • Protocol overhead should be low.
• Types of messages:
  • Notebooks (large, multimedia contents).
  • Notebook inputs (medium size).
  • Evaluation results (medium to large).
  • Control messages (small).
