Abstract
An Optimized Edge Routing (OER) technique provides efficiently data routing at the edge of a network or subnetwork. The technique employs a Master node that manages a set of border nodes located at the edge of the network or subnetwork. The Master node may be a stand-alone network management node or may be incorporated into a network node, such as a border node. Unlike prior implementations, the Master node instructs the border nodes to dynamically acquire (“learn”) prefixes of incoming and outgoing data flows and to selectively filter a set of learned address prefixes whose corresponding data flows match a predetermined set of criteria. The criteria may be based on routing metrics other than, or in addition to, conventional cost-based or distance-based metrics. Further, the criteria may include a set of filtering parameters that may be reconfigured, e.g., by the Master node, from time to time. Using the learned prefixes filtered by the border nodes, the Master node can distribute network traffic and utilize network bandwidth more efficiently than conventionally done.
