Routing schemes differ in their delivery semantics:
- unicast delivers a message to a single specific node
- broadcast delivers a message to all nodes in the network
- multicast delivers a message to a group of nodes that have expressed interest in receiving the message
- anycast delivers a message to any one out of a group of nodes, typically the one nearest to the source
- geocast delivers a message to a geographic area
Unicast is the dominant form of message delivery on the Internet, and this article focuses on unicast routing algorithms.
