when choosing an Internet plan, ISPs should publish their capping and throttling practices with the necessary level of detail. While the net effect of some throttling and capping strategies can be hard to compare across ISPs, some basic metrics that are of interest for any kind of throttled/capped Internet connection are: Maximum monthly payload: This is the amount of data that an Internet connection would be able to carry in a hypothetical setting assuming no bottlenecks external to the ISP. In the example Antel 20Mbs fiber connection (see Uruguay above), the maximum monthly payload in that hypothetical setting would be reached by running the connection at 20Mbs for the first 150 GB, and at 2Mbs for the rest of the month. Thus the maximum monthly payload of that connection is 60,000 seconds * 2.5 MB/s + 2,532,000 seconds * 0.25 MB/s = 783 GB (about the size of a large laptop disk drive in 2013.) Maximum utilization percentage: This is the ratio of the maximum monthly payload of a throttled Internet connection to the maximum unthrottled monthly payload of the same connection. In the example Antel fiber 20Mbs connection the maximum unthrottled monthly payload of that connection is 2,592,000 seconds * 2.5 MB/s = 6,480 GB. Thus the maximum utilization percentage of that connection is 783 GB / 6,480 GB = 12% Throttling percentage: This represents how much the maximum monthly payload of an Internet connection gets reduced by the ISP's throttling policy. It is calculated simply as 1 − maximum utilization percentage. In the example Antel fiber 20Mbs connection it is 1 − 12% = 88% Equivalent connection bandwidth: This is the bandwidth of an unthrottled Internet connection whose maximum monthly payload is the same as the maximum monthly payload of the throttled connection in question. This can be calculated as unthrottled connection bandwidth * throttling percentage. In the example Antel fiber 20Mbs connection the equivalent connection bandwidth is 20 Mbs * 12% = 2.4 Mbs Cost per unit payload: The ultimate metric of throttling's effect on an Internet connection's potential value to a customer is the cost per GB (or TB in the case of fast connections) carried assuming perfect utilization of the connection. It is calculated by dividing the monthly cost of the connection by the maximum monthly payload. In the example Antel fiber 20 Mbs connection it would be US$36 / 0.783 TB = US$46 per
