Like every month, Netflix publishes its ISP Speed ​​Index, which measures the average speed of its streams by country and ISP. After several months of stability, the throughput decreased in April.

Redesigned in early 2021, Netflix’s ISP report makes it possible to compare SVOD service performance with each operator in prime time. This is not a general performance metric that includes other services / data that may be circulating over a suspicious ISP network.

In France, Netflix revealed that all French operators lost 0.2 Mbits / s in April. At speeds of 3.4 Mbits / s, the SFR THD continues to lead. At the back, Orange, Boise Telecom and Free share second place at 3.2 Mbits / s. Lastly, the SFR in ADSL records speeds of 3 Mbits / s. The gaps between the four players are strong again.

The average French speed is 3.2 m / s, as in Argentina, Austria, Bolivia, Brazil, Chile, Ecuador, France, Greece, India, Indonesia, Italy, Japan, Mexico, Paraguay, Philippines, Poland, Taiwan, Trinidad and Poland. Tobago, Turkey, Uruguay, Vietnam.

Overall overall performance in Germany, Australia, Belgium, Canada, South Korea, Denmark, Spain, United States, Finland, Hong Kong, Hungary, Ireland, Iceland, Israel, Luxembourg and Malaysia (3.4 Mbits / s). Norway, New Zealand, Panama, Netherlands, Portugal, Romania, United Kingdom, Singapore, Sweden, Switzerland and Thailand.

Netflix Methodology

To measure ISP performance, Netflix follows two steps. In the first, the SVoD splits the juggernaut “Peak-time sessions to segments of 0.5 megabits per second (MBps) per second, based on maximum possible throughput, and then time-loaded throughput achieved for all sessions in each segment.” This is enough to measure the difference between the effective throughput of the combined sessions and their maximum possible throughput. Next comes the calculation of the overall time distribution of these segments and the normalization of each ISP.

This performance index includes home broadband networks. “Similarly, we are careful to avoid direct streaming from cellular networks based on the given IP address ranges / classless inter-domain routing (CIDR), Netflix specifies. This includes operators who have seen more than 1% of Netflix content in a row in the country. Finally, the maximum consumption of Netflix programs per day per ISP is defined as 3 hours of prime time. One day, it’s 7 to 9 pm, another day it’s 6 pm and then 9 to 10 pm.
