Abstract:
1. A computer-implemented method for routing information in a network, comprising: receiving, by a computer system, link state information from a plurality of network elements at various intervals, at least one network element of the plurality of network elements configured to send a portion of the link state information according to an interval of the various intervals, the received link state information being processed according to a link state algorithm into first routing information for the at least one network element of the plurality of network elements, the first routing information used by the at least one network element of the plurality of network elements to route network traffic received by the at least one network element, the at least one network element being configured to apply the link state algorithm; accessing, by the computer system, one or more policies that indicate a hierarchical categorization of the plurality of network elements, wherein a location of the at least one network element within the hierarchical categorization determines how to route the network traffic received by the at least one network element; changing, by the computer system and based at least in part on the accessed one or more policies, the received link state information such that the changed link state information is processed according to the link state algorithm into second routing information that is different from the first routing information, the changed link state information identifying at least one subnet element replacing the at least one network element that is identified in the received link state information; and providing the changed link state information to the at least one network element such that the at least one network element determines, by applying the link state algorithm to the changed link state information, second routing information to route the received network traffic.
