There are 3 factors that significantly impact call quality:Īll of these are well known by PingPlotter, covering the samples we take. MOS is an interesting number, though, and if we take a few variables that we know negatively impact call quality, we can put together a very rough approximation of what the voice call quality might be over that line. We're also measuring only once every second - or possibly less often, depending on the trace interval. It might be a web server, or a game server, or any variety of things, none of which care to collaborate on estimating how a person would measure voice quality over that connection. PingPlotter's collection methods are a bit different from all of this - we're sitting on one side of a connection, and the other end has no idea that we're measuring anything. For best results, you might take samples from the line at a similar rate to what a voice call might send data (numerous times a second). This is usually done by having both sides of the connection measure certain characteristics of the connection, and collaborate on the quality of the line and connection. There are a number of factors that play into an MOS rating, and some hardware and tool vendors have put formulas in place that can 'estimate' an MOS, based on a number of variables. In fact, there's probably not even a voice call going on over your network much of the time for us to measure. Obviously, with PingPlotter we don't have someone doing a voice call on your line all the time, and then giving an opinion number. In reality, this number is a subjective 'opinion' rating of call quality given by someone who was just on a voice call. It is used by the VoIP industry to put a number on voice quality. MOS (mean opinion score) is a voice call quality metric. PingPlotter Pro now has an 'MOS' column and alert. The clever design lets you quickly accommodate while tab support gives you the possibility to simultaneously monitor multiple URLs or IP addresses.How is MOS calculated in PingPlotter Pro? To sum it up On an ending note, PingPlotter Pro is a handy network administration tool with which you can constantly keep an eye on multiple targets and receive alerts whenever unexpected events occur. As such, you can write down a custom name for easy identification, set the number of samples to examine, the method used which can either be for latency and packet loss or MOS, multiple target configurations, as well as the action to trigger when conditions are met. Set up alerts for various scenarios The notification system gives you the possibility to set up several parameters to be announced of any changes. Bringing up the context menu enables you to manage a few more settings like obtaining whois info, display summary, show graphs or even configure alerts. Each element you select highlights all of its components for better view. Gather and save packet info As soon as the process is put in motion, all packets are displayed, with a timeline view updating in real time according to your specifications. For short-term analysis, the sampling number can be set, with the default value being unlimited, trace intervals can be specified in seconds, as well as the number of samples to include. On the other hand, there are several settings to configure, depending on the testing scenario. Hitting the “Start” button is all it takes to send a few packets to the selected target. ![]() All targets are saved in a list so you can quickly access them later on. Connecting to a target is easily done by manually writing down either the URL or IP address in a dedicated fields. Configure connection settings and trace multiple targets A neat advantage is the possibility to simultaneously trace multiple addresses, with detail windows stored in tabs. What's more, you can save your workspace configuration to use for multiple tasks and this comes in handy because you can slightly customize the view with more or less tabs and sections. Create and save custom workspaces The application's design is pretty intuitive, with adjustable panels so you can clearly view packets, timelines or project elements so you can quickly access them. Amongst others, you can use PingPlotter Pro to carefully monitor multiple addresses and trigger alerts when unexpected events occur. Keeping a network, server or a website active means constantly monitoring incoming and outgoing packets to make sure connectivity is flawless. Network administrators need to be ready for various events that don't necessarily mean virtual attacks.
