Research On Home Gateway QoS Function Based On User Online Behavior

Now home gateway is one of the main access terminals to the Internet as well as the main Internet access device promoted by most Internet Service Provider (ISP). The more the services are, the busier the Internet become. It’s important to study the home gateway QoS function to ensure the services’ quality.Traditional QoS function identifies configuration strategy by classifying the packet head, which cannot distinct services in circumstances that the service types are numerous and the port reuse is serious. Based on user online behavior, this paper presented a home gateway QoS function based on user online behaviorto make its scheduling policy accurate to service type and ensure the service which the user actually wants to guarantee. Depended on Deep Packet Inspection (DPI) technology,a service recognition software module was designed, which could distinctively mark different service packet and then place the high-priority service type in high-priority queue to make sure that the essential service implement preferentially.In addition, the upstream bandwidth of home gateway provided by Internet operators is usually much smaller than the downstream bandwidth of that. Meanwhile the protocol stack processing and forwarding of upstream take up lots of CPU resources. This paper integrated fast-forwarding technology acting as an expansion function with the QoS module, which allowed fast forwarding processing of those critical services. Besides this paper also presented a configuration method of multi-level accelerate policy of QoS on home gateway interactive platform and provided an interface to user space configuration.In a word, based on the basic function of traditional home gateway and user online behavior, this paper realized functions of distinct scheduling of services and flow control, which allowed various services within the home network to run successfully and provided home users with excellent online experience.
