Abstract

Noncompliant P2P Content Delivery Network (PCDN) services are growing rapidly, posing serious threats to network security and adversely affecting the high-value IDC bandwidth services of telecommunications operators. At present, no effective technical means for remediation and optimization have been identified within the telecommunications industry, and this situation has long troubled the industry. This paper conducts an in-depth study of the operation and maintenance of home broadband services and proposes two traffic-remediation schemes: one based on NAT optimization and modification, and the other based on the combination of PCDN user tagging and Internet Deep Packet Inspection (DPI)-based traffic-control capabilities. Large-scale deployment tests on home broadband networks show that both schemes effectively remediate noncompliant PCDN traffic in home broadband services. The results provide a new direction for research on the governance of noncompliant PCDN services.
