On Passive One-Way Loss Measurements Using Sampled Flow Statistics
—The ability to scalably measure one-way packet loss across different network paths is vital to IP network management. However, the effectiveness of active-measurement techniques depends on being able to deploy measurement hosts at appropriate locations, and to inject necessary amounts of probe traffic without impacting the performance of interest. On the other hand, existing passive-measurement methods like [1] require router support and suffer from deployment limitations for the foreseeable future. In this paper, we propose a new estimation technique that does not require any new router features or measurement infrastructure, and only uses the sampled flow level statistics that are routinely collected in operational networks. The technique is designed to handle challenges of sampled flow-level aggregation such as information aggregation and non-alignment of flow records with measurement intervals. We develop three different schemes and derive analytical bounds on the variance o...
