Abstract
An intelligent electronic device segregates urgent data frames from non-urgent data frames on reception so that the urgent data frames may be handled with greater priority. A switching device is disposed between an external network interface and multiple internal network ports. Based on a network data type indicia, urgent data frames are routed to one of the ports, and non-urgent data frames are routed to another port. A processor coupled to the internal network ports handles urgent data frames before handling any non-urgent data frames.
