Juniper Networks SRX 5000 Services processing card - control processor

As the "brain" behind the SRX services gateway, the SPCs are designed to process all available services on the gateway. Without the need for dedicated hardware for specific services or capabilities, there are no instances in which a piece of hardware is taxed to the limit while other hardware is sitting idle. All of the processing capabilities of the SPCs are designed to process all configured services on the gateway.
