mbed Net Meter: A Wall Clock Display of Real-Time Network Traffic
You can monitor network data with the mbed-based Net Meter. The clever wall clock-style design displays real-time Ethernet traffic data with three easy-to-read analog dials. The meter shows inbound and outbound data rates, as well as network bandwidth quota usage. The update rate for the "in" and "out" meters is twice per second. The "quota" meter's update rate is once every 8 seconds.
