Abstract
A technique dynamically increases the granularity of prefix control in a computer network. According to the novel technique, a routing table is populated with one or more reachable prefixes, e.g., learned or configured prefixes, and performance characteristics (e.g., bandwidth, cost, delay, etc.) of the prefixes are monitored. Upon determining that a need exists for more granular prefix control (i.e., smaller prefixes), one or more boundaries may be determined upon which to divide one or more of the prefixes based on the monitored characteristics and/or need. Once the one or more boundaries are determined, the one or more prefixes may be “split” accordingly, e.g., by injecting more specific prefixes into the routing table, thus providing more granular prefix control (i.e., by controlling the split prefixes).
