PRIORITY OF PACKET INFERENCE WITH BACK UP PATH
no vote
Packet forwarding prioritization (PFP) in routers
is one of the mechanisms commonly available to network operators. PFP can have
a significant impact on the accuracy of network measurements, the performance
of applications and the effectiveness of network troubleshooting procedures.
Despite its potential impacts, no information on PFP settings is readily
available to end users. In this paper, we present an end-to-end approach for
PFP inference and its associated tool, POPI. This is the first attempt to infer
router packet forwarding priority through end-to-end measurement. POPI enables
users to discover such network policies through measurements of packet losses
of different packet types. We evaluated our approach via statistical analysis,
simulation and wide-area experimentation in Planet Lab. We employed POPI to
analyze 156 paths among 162 Planet Lab sites. POPI flagged 15 paths with
multiple priorities, 13 of which were f
