Abstract: | Modern communication networks often use Internet Protocol routing and the intra-domain protocol OSPF (Open Shortest Path First).
The routers in such a network calculate the shortest path to each destination and send the traffic on these paths, using load
balancing. The issue of survivability, i.e. the question of how much traffic the network will be able to accommodate if components
fail, is increasingly important. We consider the problem of designing a survivable IP network, which also requires determining
the routing of the traffic. This is done by choosing the weights used for the shortest path calculations. |
