SRX1400, SRX3400, and SRX3600 Services Gateway Module Overview
The modules described in this guide let you upgrade and customize your SRX1400, SRX3400, or SRX3600
Services Gateway to suit the needs of your network. The following types of modules are available for the
SRX1400, SRX3400, and SRX3600 Services Gateways:
•
I/O cards (IOCs) are common form-factor module (CFM) cards that provide additional physical network
connections to the services gateway to supplement the Ethernet ports on the Switch Fabric Board (SFB).
Their primary function is to deliver data packets arriving on the physical ports to the Network Processing
Card (NPC) and to forward data packets out the physical ports after services processing.
•
Network Processing I/O Cards (NP-IOCs) are IOCs that have their own network processing units (NPUs),
so that traffic traversing the IOC does not have to traverse the services gateway bus to a remote NPC.
This feature makes them well-suited to low-latency applications.
•
Services Processing Cards (SPCs) are CFM cards that provide the processing power to run integrated
services such as firewall, IPsec, and IDP. All traffic traversing the services gateway is passed to an SPC
to have service processing applied to it. Traffic is intelligently distributed by NPCs to SPCs for service
