PingER Pros
Low Bandwidth utilization
The PingER MA sends up to 30 x 100Byte pings at 1 second intervals (or 800bits/second) and up to 30 1000Byte pings at 1 second intervals (8000/second) to each target until it receives up to 10 responses from the target or times out in 30 seconds. In the case of the main MA at SLAC that monitors about 800 nodes, each 30 minutes this corresponds to an aggregate data rate of ~7Mbit/sec.
Regularity of measurements
- PingER makes measurements at regular intervals and thus has results by time of day, day of month, month by month, and year by year going back to 1998.
- Also the regularity of measurements can enable measurement of the timing and impact of events such as: earthquakes, tsunamis, social upheavals, mistaken routing, changing from geo-stationary satellite links to terrestrial links etc.
- PingER has measurements by country, region.
Simplicity of set up
- PingER does not require any software to be installed in the targets.
- PingER uses common targets using the standard Internet path to them, as opposed to selecting only well-connected targets.
How does PingER differ from speed tests
This is similar to monitor-io (see https://www.monitor-io.com/monitor-io-vs-speed-tests.html), where it says:
Internet service providers typically publish upload and download speeds to describe the size of the connection to the home. The test itself is not a real-world measure; actual user traffic rarely uses the connection this way. Thus it is very rare, if ever, to actually get the published speed when using the network.
Speed tests identify a server, typically not far from the source, and send multiple large samples of data to it and then back from it. The data is significant enough to extend beyond the capacity of the connection in order to measure the time it takes to move all the information. It is similar to trying to see how many cars can move on a highway by sending a lot of cars on it until all lanes are full. Clearly, not something that should be done too often because it saturates your network.
Most applications (other than large multi-threaded file uploads and downloads) do not push the boundaries of this measurement and therefore, while useful, are not the only test of internet performance that is relevant. Most video applications, adjust the rate of transmission of packets to a comfortable speed to give the best user experience. As long as there are no other issues, most modern connections have more than sufficient bandwidth (in spite of the attempt by some internet service providers to convince subscribers otherwise).
The monitor-io service sends a small number of packets, in a planned sequence, to different destinations to measure performance. The packets are analyzed in a detailed fashion to extract the precise cause of poor performance. It is the equivalent of sending one car to see if the road is congested, and documenting the issues seen by the car. By sending packets to different points on the globe, monitor-io has a better sense of the performance across different paths and provides a more real-world view of how any end-user would experience network performance.
The device that runs the monitor-io tests is tuned to perform only this one function and is independent of any interference from other applications, thereby guaranteeing accurate measurements. When the device is connected directly to the first router on the premises, it will give the most accurate view of the performance of the internet service provider.
The service keeps track of all this data so that a user can get a historical view of the quality and reliability of their internet service. It also alerts them if there is impaired or degraded performance at any time of the day. In fact, if they do want to do a standard bandwidth speed test, monitor-io allows them to run one from directly within our site as a sanity check...but we believe that our 24x7 lightweight test sequence will be much more useful.

The line monitoring system allows you to track the performance of your broadband connection in terms of latency and packet loss. Latency is the time it takes for a piece of information (a 'packet') to get from our servers to your broadband connection, and back. Packet loss is where some bits of information are lost whilst in transit, so it has to be re-sent. These can cause problems with various 'realtime' applications such as online gaming, video conferencing, internet telephony, etc.
