Latency and fiber
If I have fiberglass, yes, then I’m ready and the party can start! Ever heard of latency? If you buy a Ferrari (red of course) and go with it to a motocross, a Quad will beat you and race faster over the bumps. No, it’s all about the “latency” these days.
Latency is the time required to transfer data between the original source and the destination, measured in milliseconds.
Games and streaming video are examples for applications whereby latency plays a major role. If the processing of the data is too slow, shocking images arise and no one likes to see that spinning circle on his screen.
This is also of great importance in the financial sector, transactions must be ready in a few milliseconds, this is called low-latency trading. That is why they also use ECN, this stands for Electronic Communication Network. Without ECNs, it would take considerably longer for buyers and sellers to be matched with one another, making it more difficult to enter or exit positions and adding to the costs and risks of trading.
Therefore the measuring and monitoring of complete connections from application to application level is becoming increasingly important. From point A (client) to B (server), but do not forget that you can also go from point C, D, E, F to B, the latency of one client does not have to be equal to the latency of the other client. And so you already get a nice insight into where the problems are and especially where they are NOT, a matter of exclusion. Of course, monitoring the individual components that you link together is also important, but say for yourself: “If the latency is zero loss (does that actually exist :-)), what else will you worry about.”
