DCP
DCP can be expanded in two ways:
-
A control traffic rate limiting protection mechanism for the CPM/CFM that operates on the line cards (hence ‘distributed’). CPU protection protects the CPU of the node that it is configured on from a DOS/DDOS attack by limiting the amount of traffic coming in from one of its ports and destined to the CPM (to be processed by its CPU) using a combination of the configurable limits.
