Quality of service test mechanism and management of broadband access network

摘要

As the growth of digital home application, the quality of service (QoS) of network is a very critical issue and influences the satisfaction of end users to enjoy the desired service, especially for real-time sensitive service. It is important for service provider to verify the actual QoS parameters, such as delay, jitter and packet loss are satisfying the service requirement of their customers. The popular method to check the QoS is using ICMP ping function to gather the QoS parameters, but results in the precision argument and lacks of one-way information for IPTV downstream flow. The other issue is how to activate the QoS test function for the large scale CPEs (Customer Promise Equipment). In this research, we propose a QoS test mechanism at home gateway to exclude all factors of home networking. The proposed approach integrates the TR-069 remote management methodology to increase the scalability to activate the proposed QoS test action for a large number of home gateways. We illustrate the implementation and integration procedure of the proposed test approach and TR-069 mechanism of the managed home gateway. We also execute the proposed test by TR-069 management server, and comfirm its accuracy. The proposed mechanism provides a convenient way for the service providers to clarify the service quality of subscribed lines of broadband access network, and decreases the complaint and increases the satisfaction of their customers.
