SFC

SFC is expanded two ways:

1. Static Filter CWDM

   A static filter card used with a CWDM circuit pack.

2. Service Function Chain

   A service function chain uses SDN capabilities to create a service chain of network services, such as firewalls and NAT, that are connected in a virtual chain. Network operators can then set up suites of connected services that use a single network connection. SFC automates the setup of virtual network connections to handle traffic flows for connected services.
