Link State Protocol
- Who: Send to all nodes
- What: Send Link state packet (LSP) about direct connected links
- When: Periodically or when a change occurs (triggered)
The point is that Local information is distributed globally.
The LSP information recieved is used to create a graph of the network. Then routing is easy because we use DijkstrasAlgorithm, to find the shortest path. See cse952lec03.pdf
Uses OpenShortestPathFirst OSPF algorithm
