IP address and configuration activation time settings by the DHCP server in the attached network (which includes setting of DNS servers IP addresses via DHCP). DNS response time It defines average Round-Trip-Time (RTT) delay metric for DNS response in IP networks, which is directly dependent upon the distance between the DNS client and the DNS server, and DNS server average domain name resolution time. Number of IP network This refers to number of interconnection points to other Autonomous interconnection Systems (ASs). points RTT to IP network This metric measures the RTT between subscribers' service demarcation interconnection points and the interconnection points to other ASs. Typically, such points interconnection points are located at the Internet eXchange Points (IXPs). The IP packet delay is defined as average of (t2-t1) over all successful and errored packet outcomes between occurrence of two corresponding packet reference events, ingress event at time t1 and egress event at time t2. One-way IP delay This is one-way delay variation to IP network interconnection points. variation [24] One-way IP packet This is one-way packet loss to IP network interconnection points. loss [24] Mean data rate This is the average of the data transfer rate achieved for transfer of a given achieved (separately number of samples (e.g. download or upload of file samples with a given for downlink and size - the higher the bitrate, the larger the sample file should be in order uplink directions) to provide realistic measurement of the data rate because TCP with its Slow Start needs many RTTs until it reaches the available data rate). Percentage deviation This denotes the deviation between the data rate contracted (advertised) of the mean data rate to the achieved data rate, obtained as: (i.e. mean bitrate of |contracted_rate - achieved _rate Internet Access Deviation[%] = contracted. rate Service - IAS) Internet IP network Represents the fraction of time probability that the end-user is able to service availability access services
