Parameter FTP {download | Upload} Mean Data Rate [Mbit/s] Definition Formula The FTP {download | Upload} Mean data Rate [Mbit/s] is the average data transfer rate measured throughout the entire connect time (i.e., after a data link has been successfully established) to the service.) FTP {download | Upload} Mean data Rate = (User data transferred (Kbit) / (Time data transfer complete – Time data transfer Start) Target Urban ≥ 1 Mbit/s (4G) Rural ≥ 512 Kbit/s (4G) Fixed Broadband Internet Service Data Transmission Rate The speed of data travelling from user to the network and back. Data transmission Rate = Size of Test file /the transmission time required for a complete and errorfree transmission >80% of the advertised speed during peak time Access Network Utilization Access Network Utilization is a parameter that measures the total traffic between access node to aggregation node. Access Network Utilization = (Total traffic between access node / Aggregation of traffic at the node) X100% Uplink utilization must not be more than 75% of the uplink bandwidth provided Latency The duration of time it takes, in milliseconds (ms), for a data packet to reach the receiving endpoint after being transmitted from the sending end-point. Latency (ping roundtrip) = 𝑡𝑝𝑎𝑐𝑘𝑒𝑡 𝑟𝑒𝑐𝑒𝑖𝑣𝑒𝑑 − 𝑡𝑝𝑎𝑐𝑘𝑒𝑡 𝑠𝑒𝑛𝑡 [ms] <80ms for local target server and for xDSL access technology. <50ms for local target server and for xDSL access technology . <25ms for local target server and for FTTH access technology <50ms for local target server and for FTTH access technology Packet Loss Packet loss means the measure of the percentage of data packets transmitted from source that fail to arrive at their destinations. (Total Number of Packet Loss/Total Number of packets Sent) X100% <0.5% for 95% of tests of FTTH networks <2% for 95% of tests of xDSL networks 15
