Applying Traffic Rate Limits with Special Rules

The Tofino Central Management Platform (CMP) software provides visual drag-and-drop editors that permit the control systems engineer to create rules defining which devices on the control network are allowed to communicate with each other, and what protocols they are permitted to use. Another type of pre-defined rule, called Special Rules, allow the Tofino Security Appliance (SA) to implement more advanced filtering rules that cannot be expressed visually. This application note explores several special rules that implement traffic rate limiting.
