Different types of traffic flow

  • Unicast, packets to every requesting address, traffic may be carried multiple times, the primary concern is the number of network connections versus the available bandwidth. Each session requires the the full bandwidth required by the application.
  • Broadcast, one copy of a packet is send out to a broadcast address. Broadcast are stoped by layer 3 devices unless allowed to be forwarded. So evyer device with the same broadcast address receives the packet.
  • Multicast, for transporting multimedia data, a media server sends a single copy to a predetermined multicast address, replications occurs only, when necessary
