Additional data that is used to provide relative geolocation are TTL (hops), Round Trip Times, and One-Way Delay metrics. For argus data derived from Netflow data, AS numbers can be used to provide a form of netlocation. For pure argus data, the Layer 2 and Layer 3 network addresses that are contained in the flow data records provide the basis for geographically placing the data. There are a lot of definitions for geolocation, but for argus data, geolocation is the use of argus object values for geo-relevant positioning.
