Network Processing Card SRX3K-NPC
Network Processing Cards (NPCs) are CFMs that receive inbound traffic from the IOCs and direct it to
the appropriate SPC for services processing. Once services processing is complete, the NPC receives
outbound traffic from the SPC(s) and directs it back to the appropriate IOC. Additionally, the NPC performs
the following functions:
•
Buffers incoming traffic and queues outgoing traffic.
•
Performs advanced traffic management, including DoS/DDoS protective measures. For example, it can
drop traffic to or from a particular IP address, protecting from ICMP, UDP, and TCP SYN flooding, and
buffering bursty traffic to protect the SPC.
