Multicast is a type of transmission from one point, or one sender, to a defined group of receivers. These can also be defined network nodes.

Multicast is also referred to as point-to- multipoint connection( P2MP). With multicasting, information is transmitted along the optimal transmission path with as little duplication as possible. The advantage of multicasting is that messages can be transmitted simultaneously via one address to several subscribers or closed user groups(GBG) without the required bandwidth increasing with the number of receiving devices.
