Routing Algorithms (2)

Conflict between fairness and optimality.

Link State Routing

Each router must do the following:

• Discover its neighbors, learn their network address.

• Measure the delay or cost to each of its neighbors.

• Construct a packet telling all it has just learned.

• Send this packet to all other routers.

• Compute the shortest path to every other router.
