First, I want to test the data rate of a fibre-optic internet connection, but I understand that results are affected by the circumstances of the test, like number of hops between the CPE and the other end-node, time of day, etc, which ultimately impact the test results. Also, I need the most standard, universally accepted definition of bandwidth capacity of an internet connection to ensure that the test is performed and measures the most formal correct way possible, to make sure the test pass scrutiny.
Second, I must make a report with the results. So I need to refer to the definition in the literature. Therefore the question is simple, what is the most universally accepted definition of the term ‘bandwidth capacity’ of an internet connection? Please also include a reference from relevant litterature that you recommend for the purpose.
