TextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbook

Answer

Differences between the broadcast abstraction via multiple unicasts and single network router supported broadcast:

  • multi-way unicast  generates multiple copies from the source node. It is used to find the address of the all the destination nodes.
  • Single network router generates duplicate copies to send destinations at same time. It is used to  find all the destination addresses. Using unicast routing, the source node then transmits N copies to N destinations.
