The ~~FB6000~~ ~~[[L2TP]]~~ ~~router~~ ~~provides~~ us with Continuous Quality Monitoring ~~(CQM)~~. This allows us to track the quality of each and every connection in great detail. The router itself produces the graphs in real time, and can also provide csv files with accurate data for each graph.

The FireBrick 6000 routers we use provide us with Continuous Quality Monitoring of every broadband circuit. This allows us to track the quality of each and every connection in great detail. The router itself produces the graphs in real time, and can also provide csv files with accurate data for each graph.

Customers and Staff can view these graphs in near real time (updated every 100 seconds), and can view historical graphs.

==How does it work?==

Our router sends an LCP echo (like a ping) every second while a line is active. Your router replies. We track how long it takes for each reply to arrive, and how many are lost. These results are collated into 100 second samples and shown as a graph like the one on this page. The graph shows us lots of information about the line, and gives a history covering the last 24 hours.

Each column (pixel) represents 100 seconds of samples. The hour of day is shown at the bottom, and the day and date shown next to midnight in the graph. There is additional text superimposed on the graph such as a circuit ID. ~~There are 8 pieces of data shown for each 100 second sample as follows:-~~
