| Abstract | IP networks are increasingly carrying mission-critical appli-cations with robust end-to-end network performance and reliability requirements. Network performance monitoring forms an essential component of critical IP network man-agement functions such as troubleshooting, anomaly detec-tion, and Service-Level-Agreement (SLA) compliance moni-toring. However, privacy and security considerations are fu-eling the use of IP-level encryption techniques such as IPsec, which obscure important transport layer features that exist-ing performance measurement techniques need. New tech-niques are therefore needed for monitoring performance of encrypted traffic. Towards this goal, in this paper we present a new technique for monitoring round-trip times (RTT) for IP-level encrypted communications. Our approach involves using network-level features like packet size and inter-packet timing to infer specific timing events, and aggregating mea-surements across short time intervals and related connec-tions to derive final RTT estimates for network paths of interest. Extensive evaluations using traces from an enter-prise and a broadband access network, demonstrate that the resulting RTT estimates are quite accurate. |
