Hi,
The details about the CP are given in the link below :-
The central point in the architecture has two basic flow functionalities: load balancing and traffic identification (global session matching). The central point forwards a packet to its Services Processing Unit (SPU) upon session matching, or distributes traffic to an SPU for security processing if the packet does not match any existing session.
The CP sessions as well as the flow sessions reaching the limit could impact the SRX and traffic passing through it.
