Unicast
Unicast is a type of communication where data is sent from one computer to another computer. Unicast is a one-to-one type of network communication. Different data streams are generated for each Unicast connection. This type of communication is the option when clients need different data from network server.
Multicast
Multicast is a type of communication where multicast traffic addressed for a group of devices on the network. IPv6 multicast traffic are sent to a group and only members of that group receive the Multicast traffic.
Anycast
Anycast is a type of IPv6 network communication in which IPv6 datagrams from a source are routed to the nearest device (in terms of routing distance) from a group servers which provide the same service. Every nodes which provide the same service are configured with same Anycast destination address.
