	att_abstract={{Abstract�Recent trends in the networked services industry
(e.g., CDN, VPN, VoIP, IPTV) see Internet Service Providers
(ISPs) leveraging their existing network connectivity to provide
an end-to-end solution. Consequently, new opportunities are
available to monitor and improve the end-to-end service quality
by leveraging the information from inside the network. We
propose a new approach to detect and localize end-to-end
service quality issues in such ISP-managed networked services by
utilizing traffic data passively monitored at the ISP side, the ISP
network topology, routing tables and geographic information.
This paper presents the design of a generic service quality
monitoring system �Argus�. Argus has been successfully deployed
in a tier-1 ISP to monitor millions of users of its CDN service
and assist operators to detect and localize end-to-end service
quality issues.This operational experience demonstrates that
Argus is effective in accurate, quick detection and localization of
important service quality issues.}},
