Routing schemes
From wikinotes
Routing Schemes describe how a piece of information is sent from one point to another. Routing schemes can be implemented at different levels in the networking stack.
| unicast | send message from one node, to another node. |
| anycast | sends message to one of several nodes, generally chosen/scored by distance, speed, etc. |
| multicast | sends messages to a group of target computers all at the same time. |
| geocast | a form of multicast where message is sent to nodes based on their geographical location |
| broadcast | send message to all computers on a network at once. |
