US Patent 8144611 Network coordinate systems using IP information

Systems and methods that improve predictions of network latency in network coordinate systems (NCS) based on combining Internet topology information therewith. Topology information can be incorporated into the NCS by system/methodologies represented by geographic bootstrapping; autonomous system (AS) correction; history prioritization; symmetric updates or a combination thereof. Such can improve latency estimation between nodes when using a virtual coordinate system based on latency measurements between nodes.
