Abstract:
1. A method comprising: generating, at a measurement device executing a measurement application, a probe that comprises a time-to-live field; disabling, by the measurement device, changes to the time-to-live field of the probe; inserting, by the measurement device, the probe at an in-band connection; initiating routing, by the measurement device, of the probe to an extraction point located at an end of a measurement line via an insertion point being located at a beginning of the measurement line, wherein the changes to the time-to-live field are enabled by a device associated with the insertion point when the probe reaches the insertion point, and wherein the changes to the time-to-live field are disabled by a device associated with the extraction point when the probe reaches the extraction point so the probe measures only network path changes occurring at the measurement line; receiving, at the measurement device, the probe; analyzing, by the measurement device, the probe; and measuring, by the measurement device, the network route reconvergence based upon a value in the time-to-live field, wherein the time-to-live field reflects only the network path changes occurring at the measurement line.
