摘要
Abstract
The fundamental principles and technical advantages/disadvantages of Deep Packet Inspection(DPI)and Deep Flow Inspection(DFI)technologies are primarily elaborated,it analyzes the current management status of IPTV systems in existing Service networks,through collecting and analyzing traffic characteristics of IPTV service control information and vid-eo data,we establish a critical video feature database and priority hierarchy based on traffic patterns,leveraging DPI/DFI technologies enables precise identification of various IPTV-related traffic types,a refined IPTV traffic management process is designed,implementing an integrated hardware-software IPTV traffic management system,a testing environment was con-structed with evaluation metrics to examine:IPTV video display under normal bandwidth conditions,video performance dur-ing bandwidth threshold exceedance and video quality after implementing priority protection strategies,experimental results demonstrate the DPI/DFI based IPTV traffic control achieves accurate traffic identification and granular control,effectively mitigating the impact of network congestion on service quality.关键词
