Question

Using AIT (Lecturers, Students, Administrators and the President) as an example, explain Unicast, Broadcast, Multicast and Anycast transmissions. In addition, use well labelled diagrams to further depict your explanation.

Answer 1

UNICAST TRANSMISSION
A unicast transmission is a 1:1 communication passing from a single source to a single destination. One of the simplest everyday examples of unicast transmission would be a phone call between two people.
It has easy to deploy techniques.

BROADCAST TRANSMISSION
A broadcast transmission is capable of transmitting the same information to all nodes on a network simultaneously. Ensuring that the broadcast is reaching all “corners”, the transmission refereses or relays at certain points. Television signals sent from a public network to viewers across the country or globe are a simple example of broadcast transmission.

MULTICAST TRANSMISSION
A Multicast transmission is a “one-to-many” transmission technique in which information is sent from a single source to as many recievers or destinations as express a specific interest in receiving it. So it’s an “on demand” system capable of catering for the likes of pay per view, or similar subscription-based services.

ANYCAST TRANSMISSION
Anycast is a network addressing and routing method in which incoming requests can be routed to a variety of different locations or “nodes.” In the context of a CDN, Anycast typically routes incoming traffic to the nearest data center with the capacity to process the request efficiently.
