public class AggregateShortestPath

extends ShortestPath

A routing table that uses global knowledge to route packets on the shortest path. If changes are made to the topology, the update shortest path (usp) command must be run. If an ip does not exist, an attempt is made to route to the /16 subnet it is in

Method Detail

lookup

public int lookup(int to)

Determines the ID of the next hop in the path to the specified node. If no path can be found, try to route to the /16 subnet.

Overrides:

lookup in class ShortestPath

Parameters:
