This section outlines the Danube use cases driving the initial OPNFV SFC implementation.
This use case is targeted on creating simple Service Chains using Firewall Service Functions. As can be seen in the following diagram, 2 service chains are created, each through a different Service Function Firewall. Service Chain 1 will block HTTP, while Service Chain 2 will block SSH.
This use case creates two service functions, and a chain that makes the traffic flow through both of them. More information is available in the OPNFV-SFC wiki:
