By the book – MPLS TRAINING GUIDEBy Rick Gallaher. • “I personally prefer standalone components to perform policing and traffic accounting. The argument is as old as the stereo system arguments that pitted integrated systems against component-based systems. I like to have component-based policing and accounting, because it gives network analysts better control over their data. There are several policy-based policing “switches” on the market. I have had good luck with Allot’s NetEnforcer for policy-management and accounting purposes.” • Rick Gallaher.
