Abbreviated PIM, a multicasting routing protocol that runs over an existing unicast infrastructure. There are two variations of PIM:

  • PIM-SM — Short for PIMSparse Mode, which is used when recipients are scattered over a large area.
  • PIM-DM — Short for PIMDense Mode, which is used when the targeted recipients are in a concentrated area.
