1.4. Use Cases

This section outlines the Danube use cases driving the initial OPNFV SFC implementation.

1.4.1. Use Case 1 - Two chains

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.


1.4.2. Use Case 2 - One chain traverses two service functions

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:
