The project
The problem
• Connectivity in LAC is good
but not optimal
• Presence of IXPs, but inter-
country connectivity still has to
be improved
• Information about connectivity
is not easy to find or updated
The solution
• Objective
Provide representative and
up-to-date connectivity
measurements to anyone
interested in them
• How
Latency measurements from
many origins, to many
destinations, via different
protocols

Why bother with the
browser?
Pros
• Standard and widely-used
technologies
• Ran at the end user
• Can trigger measurements
automatically
• Scales fast
Cons
• Browser and operating system
combination differences
- TCP connections are handled
differently by browser and OS
combination!
- Browser Javascript engines vary
- OSes handle processes
differently
• Need of normalising different
environments!

Testing our tool in
Browserstack
• Cloud-based testing service aimed
at web developers to check the
look & feel and responsiveness of
their sites
• We use it to run our Javascript tool
over many different OS and
browser combination
• We used automated Selenium tests
