Indirect measurement of user traffic on links

摘要

Systems and methods are disclosed herein for measuring the traffic flow on a link. The system includes a processor that is configured to generate aggregate egress data for multiple origin endpoints by aggregating amounts of egress traffic detected by servers processing the egress traffic at the origin endpoints. The processor is also configured to obtain the proportions of traffic flows that traverse each path between each endpoint pair, which includes an origin endpoint and a destination endpoint. Each path includes multiple network links such that a single network link may be shared across multiple paths. Finally, the processor computes an amount of traffic flow on a shared link based on the aggregate egress data and the obtained proportions.

1. A method for measuring traffic flow on a first link, comprising:
generating, by a processor, aggregate egress data for each of a plurality of endpoints by aggregating amounts of egress traffic detected by servers processing the egress traffic at the respective endpoints; obtaining, by the processor, for a plurality of pairs of endpoints from the plurality of endpoints, proportions of traffic flows that traverse each of a plurality of paths between respective pairs of endpoints, wherein each of the plurality of paths includes a corresponding plurality of network links, and at least one path between a first of the endpoint pairs and at least one path between a second of the endpoint pairs both include the first link; and computing, by the processor, an amount of traffic flow on the first link based on the aggregate egress data and the obtained proportions.
