As the growing development of network architecture and Information Technology (IT), existing Quality of Service (QoS) measurement mechanism is not appropriate for the virtualization network architecture. It is important for service providers to satisfy the Service Level Agreement (SLA) of their customers when the network infrastructure is transiting to the next-generation. The popular method to verify the QoS parameters is using active measurement such as ICMP ping function and UDP Echo Plus message defined in [1], but both of them are lack of one-way latency measurement capability because they are not needed to time synchronizing on the two endpoints at first. In this paper, we will investigate the measurement mechanism and Network Function Virtualization (NFV) of home gateway nowadays, including components, protocol, and considerations. Then, we illustrate the procedure of Two-Way Active Measurement Protocol (TWAMP) defined in RFC 5357 [2] and development in the standard and market. Finally, depending on the requirements, such as network quality analysis and obstacle warning from service providers, we proposed our mechanism for the service providers to clarify the quality of service of subscribed lines of broadband access network, and decrease the complaint and increase the satisfaction of their customers.
