LAN transmission methods fall into 3 main categories:
•Unicast transmission
•Multicast transmission
•Broadcast transmission
Unicast Transmission
In unicast transmissions, a single data packet is sent from a source to a single destination on the network.
Unicast Process
•The source addresses
the packet with the
destination address.
•The packet is sent into
the network.
the network.
•The network delivers the
packet to the destination.
Multicast Transmission
In multicast transmissions, a single data packet is copied and sent to specific destinations on the network
Multicast Process
•The source addresses the packet
using a multicast address.
•The packet is sent into the
network.
•The network copies the packet.
•A copy is delivered to each
destination that is included in the
multicast address.
Broadcast Tranmission
In multicast transmissions, a single data packet is copied and sent to specific destinations on the network
Broadcast Process
•The source addresses the packet with the broadcast address.
•The packet is sent into the network.
•The network copies the packet.
•The packet copies are delivered to all destinations on the
network.

•The source addresses the packet
