| 10 | Sample APEX Policy in TOSCA format |

| 14 | |
| 15 | An example APEX policy in TOSCA format for the vCPE |
| 16 | use case can be found here: |

| 23 | My First Policy |
| 24 | ^^^^^^^^^^^^^^^ |
| 25 | |
| 26 | .. container:: paragraph |
| 27 | |
| 28 | A good starting point is the ``My First Policy`` example. It |
| 29 | describes a sales problem, to which policy can be applied. |
| 30 | The example details the policy background, shows how to use |
| 31 | the REST Editor to create a policy, and provides details for |
| 32 | running the policies. The documentation can be found: |

| 38 | VPN SLA |
| 39 | ^^^^^^^ |
| 40 | |
| 41 | .. container:: paragraph |
| 42 | |
| 43 | The domain Policy-controlled Video Streaming (PCVS) contains |
| 44 | a policy for controlling video streams with different |
| 45 | strategies. It also provides details for installing an |
| 46 | actual testbed with off-the-shelve software (Mininet, |
| 47 | Floodlight, Kafka, Zookeeper). The policy model here |
| 48 | demonstrates virtually all APEX features: local context and |
| 49 | policies controlling it, task selection logic and multiple |
| 50 | tasks in a single state, AVRO schemas for context, AVOR |
| 51 | schemas for events (trigger and local), and a CLI editor |
| 52 | specification of the policy. The documentation can be found: |

| 58 | Decision Maker |
| 59 | ^^^^^^^^^^^^^^ |
| 60 | |
| 61 | .. container:: paragraph |
| 62 | |
| 63 | The domain Decision Maker shows a very simple policy for |
| 64 | decisions. Interesting here is that the it creates a Docker |
| 65 | image to run the policy and that it uses the APEX REST |
| 66 | applications to update the policy on the-fly. It also has |
| 67 | local context to remember past decisions, and shows how to |
| 68 | use that to no make the same decision twice in a row. The |
| 69 | documentation can be found: |
