<h1 id="openslice-service-orchestration-and-order-management-osom">Openslice Service Orchestration and Order Management - OSOM</h1>
<p>OSOM is a service responsible for:</p>
<ul>
<li>Service Order Management (SOM)</li>
<li>Service Orchestration (SO)</li>
</ul>
<p>It uses open source Flowable Business process engine (https://www.flowable.org) .</p>
<p>A Service Order follows the states as defined in TMF641 specification: </p>
<p><a href="../../images/service_order_states.png"><img alt="Service Order state" src="../../images/service_order_states.png" /></a></p>
<h2 id="initial-state">Initial state</h2>
<p>When a new order is created, it goes into the Initial state. It is stored in the repository and triggers an Event.</p>
<p><a href="../../images/service_order_initial_state.png"><img alt="Initial state" src="../../images/service_order_initial_state.png" /></a></p>
<p>Administrators are notified usually from the Ticketing System of a new order. They login to Openslice and change the State of the order either to ACKNOWLEDGED or REJECTED. If ACKNOWLEDGED they can Propose a startDate, add Notes, and add any additional service items</p>
<h2 id="order-scheduler">Order scheduler</h2>
<p>A process checks every 1 minute for ACKNOWLEDGED orders.</p>
<p><a href="../../images/order_scheduler_bpm.png"><img alt="Order scheduler BPM" src="../../images/order_scheduler_bpm.png" /></a></p>
<p><a href="../../images/order_scheduler_diagram.png"><img alt="Order scheduler" src="../../images/order_scheduler_diagram.png" /></a></p>
<p>It retrieves all orders that are in ACKNOWLEDGED state and if the start date is in time it will initialize the process by settingn the order in IN_PROGRESS state. Finally the Start Order Process will start.</p>
<h2 id="start-order-process">Start order process</h2>
<p>This process for now is a draft simple prototype to make a simple orchestration via NFVO. Here the actual Services (TMF638/640 model) are created and attached to Service Order and Service Inventory.</p>
<p><a href="../../images/start_order_process_bpm.png"><img alt="Start Order BPM" src="../../images/start_order_process_bpm.png" /></a></p>
<p><a href="../../images/start_order_process_diagram.png"><img alt="Start Order interactions" src="../../images/start_order_process_diagram.png" /></a></p>
<p>We expect here to check which tasks can be orchestrated by NFVO and which by human. We create the equivalent Services(TMF638/640 model) for this order.</p>
<ol>
<li>During check it should decide to create Service(s) for this service order O1 and send it to ServiceInventory</li>
<li>The Services(TMF638 model) are assigned to the Order O1 In supportService List</li>
<li>Each OrderItem OI1 is related to one serviceSpecification</li>
<li>Each ServiceSpecification has also related serviceSpecRelationships</li>
<li>So if we receive an order O1 for a ServiceSpec A which relates to (a bundle of) 3 specs(2 CFS, 1 RFS) we do the following:<ol>
<li>Create a Service S_A(TMF638 model) for ServiceSpec A for Order O1</li>
<li>We create also 3 Services S_C1, S_C2 and S_R1 equivalent to the serviceSpecRelationships (2 CFS, 1 RFS) </li>
<li>At this point the order will have 1 Local Service Orchestration Process(S_A),  2 supportingServices  refs(S_C1, S_C2) and 1 supportingResource(S_R1)</li>
<li>The 3 supportingServices and 1 supportingResource correspond to total 4 Services in ServiceInventory</li>
<li>Service S_A will have: <ol>
<li>startMode 1: Automatically by the managed environment</li>
<li>State: RESERVED and the Lifecycle will be handled by OSOM</li>
</ol>
</li>
<li>Services S_C1 and S_C2 we decide that cannot be orchestrated then they have <ol>
<li>startMode: 3: Manually by the Provider of the Service</li>
<li>State: RESERVED and the Lifecycle will be handled by OSOM</li>
<li>If the CFS is a bundle spec it is further recursively orchestrated </li>
</ol>
</li>
<li>Service S_R1 will have <ol>
<li>startMode 1: Automatically by the managed environment.</li>
<li>State: RESERVED</li>
<li>IF The Service has the characteristic CharacteristicByName( "NSDID") it will be further processed by the NFVO </li>
</ol>
</li>
</ol>
</li>
</ol>
<p>There will be two instances of task "User Task Manual Complete Service" each for Services S_C1 and S_C2. The task is Transient for now. It displays only the services that are not automated! 
Here is a flow for future:</p>
<ol>
<li>We wait here for human decision.</li>
<li>From API we get a result:
    a. If set to ACTIVE/TERMINATED then we complete the task
    b. In any other state we stay in this task until it is resolved as in step a
    c. The Status of ORDER O1 is also updated to PARTIAL</li>
</ol>
<p>There will be an instance of  NFVODeploymentRequest process  each for Service S_R1. (see later)</p>
<ol>
<li>This process is related with the NFVO orchestration</li>
<li>It will send a msg to NFVO(s?) for a specific deployment request</li>
</ol>
<p>All services in "Order Complete" are in a status:</p>
<ol>
<li>Depending on the result the service S_A is either ACTIVE or INACTIVE or TERMINATED</li>
<li>The Status of ORDER O1 is also updated to COMPLETED  or PARTIAL (in case we have some services running) or FAILED (in cases we have errors)</li>
</ol>
<p>A Service follows the states as defined in TMF638 Service Inventory specification: </p>
<p><a href="../../images/service_states.png"><img alt="Service state" src="../../images/service_states.png" /></a></p>
<h2 id="nfvodeploymentrequest-process">NFVODeploymentRequest process</h2>
<p><a href="../../images/NFVODeploymentReq_process.png"><img alt="NFVODeploymentRequest BPM" src="../../images/NFVODeploymentReq_process.png" /></a></p>
<p>This process is related with the NFVO orchestration
It will send a msg to NFVO(s?) for a specific deployment request
Then it checks the deployment status. It will wait 30 secs each time until the deployment is running (or failed)</p>
<h2 id="check-in-progress-orders-process">Check In Progress orders process</h2>
<p>Every 1 minute the "Check In Progress Orders" process is executed checking if a supported Service changed state (i.e. to ACTIVE) then the whole Order will change state (e.g. go to COMPLETED)</p>
<p><a href="../../images/check_inProgress_orders.png"><img alt="Check In Progress BPM" src="../../images/check_inProgress_orders.png" /></a></p>
<h2 id="external-service-provider-deployment-request-process">External Service Provider Deployment Request process</h2>
<p><a href="../../images/externalSPDeploymentReq.png"><img alt="External Service Provider Deployment Request process BPM" src="../../images/externalSPDeploymentReq.png" /></a></p>
<p>This process contains tasks for submitting order requests to external partners.
- Submit Order To External Service Provider Task: This task creates automatically a Service Order request to a 3rd party provider SO that hosts the Service Specification
- Check external service order fulfillment task: This task Check external partner for Service creations and updates our local inventory of services the service characteristics of remote Service Inventory</p>
<h2 id="fetch-partner-services-process">Fetch Partner Services Process</h2>
<p><a href="../../images/fetchPartnerServices.png"><img alt="Fetch Partner Services Process BPM" src="../../images/fetchPartnerServices.png" /></a></p>
<p>Every 2 minutes the "fetchPartnerServicesProcess" process is executed checking remote Partner Organizations for changes in the published catalogues.
The Fetch and Update External Partner Services Task is executed in paralle l for each Partner Organization </p>
<h2 id="local-service-orchestration-process">Local Service Orchestration Process</h2>
<p><a href="../../images/LocalServiceOrchestrationProcess.png"><img alt="Local Service Orchestration Process BPM" src="../../images/LocalServiceOrchestrationProcess.png" /></a></p>
<p>This process handles automatically services that need to be further orchestrated or processed by OSOM. For example, for a CFS Bundled service we create such automated service instances that just aggregate the underlying services. </p>
