In general, QoS measurement methodology, the protocol used – including reporting – should be capable of estimating at least the set of QoS parameters based on packets transmitted between specified measurement points. It is important to know the characteristics of a connectionless service – such as IP and NGN – that deliver user data via standalone packets (IP packets, i.e. datagrams) in each direction. As outbound and inbound traffic routes may differ, targets and measurements for all QoS attributes are in this case practically one-way, reflecting the connectionless nature of the service. Measurement probe packets should traverse as much as possible the same path as customer packets having the same QoS service class and the same QoS mechanisms in routers along the path. The value of probe packets should be appropriately set for the QoS class to be measured. This chapter examines concrete measurement tools and platforms for broadband QoS measurement, and presents selected country case studies on broadband QoS measurement, while tools for measurement are provided in annex to this manual.
