Multicast applications are useful for dissemination of information to multiple clients, where clients do not require reception of the entire content. A typical application is a cable-TV-like service, where clients can join a channel in the middle of a transmission, and leave before it ends. The data is sent only to relevant ports. Forwarding the data only to the relevant ports conserves bandwidth and host resources on links. Cisco Small Business 200 Series Smart Switch Administration Guide 191
