This project aims to assess the quality of connection from the main Portuguese ISPs to the largest public cloud providers on the internet. An active monitoring tool was developed to run measurements on personal computers against virtual machines located in the different cloud providers. During one month different metrics were collected and the conclusions shows which ISP and cloud providers has the best metrics results
Data collected per measurement:
- latency (ms)
- jitter (ms)
- packet loss (%)
- download (Mbps)
- upload (Mbps)
- target (azure/aws/ibm/google/alibaba)
- isp (ASN)
- device operating system (linux,windows,macos,android,iphone) iperf3 python library not works on Windows!
- date
