摘要： In one embodiment, a method includes: obtaining network flow information from devices in a network, where the network flow information from a respective device of the plurality of devices corresponds to one or more data flows that traverse the respective device; and producing network flow sub-files according to specified network flow characteristics that characterize a first key space using the network flow information, where the specified network flow characteristics satisfy one or more performance criteria. The method also includes: generating inter-autonomous system (inter-AS) traffic sub-files by converting the network flow sub-files to a second key space, where each of the inter-AS traffic sub-files includes one or more inter-AS flows that characterize data traffic between at least two external AS's that traverses the network; and generating an inter-AS traffic file based on the plurality of inter-AS-traffic sub-files in order to monitor traffic traversing network.

摘要： In one embodiment, a method includes: obtaining a query for network traffic associated with an interface of a node in a network. The method includes obtaining a plurality of traffic counters associated with the interface based on an interface map, where each of the traffic counters characterizes an amount of traffic traversing the interface for a particular monitoring period. The method includes determining a traffic result for the interface based on the plurality of traffic counters, where the traffic result is a function of the network traffic handled by the interface over a predetermined time period. In some implementations, the interface map includes an entry for each interface in the network, and each entry is characterized by a pointer to a list including a plurality of traffic counters for a corresponding interface and a characterization vector associated with the corresponding interface.
