Network Protection

In many national transport networks such as US networks, there is a type of special sub-topology. That is, between two hub nodes with high nodal degrees, there are several degree-two nodes connected in a chain. Figure 1 shows an example of such a type of node chain, in which node 1 and node 4 are [...]

Node failure protection is to protect a network from a node failure. Though compared to link failure, node failure is a rare event, the consequence of a node failure is much more serious, which interrupt all the service flows that go through the node as well as all the local traffic that is collected and [...]
