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

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 OPNFV-SFC wiki:
