SDN-R Frankfurt

Goal for Frankfurt version is disaggregation of SDN-R into three major parts.

1. UXWeb - Web service
2. Devicemanager - Device controlling
3. WTDB - Database

More detailed information under SDN-R Release/SDN-R Release Frankfurt

A further goal is the the enable SDN-R to be used and extended by O-RAN-SC.

• model-driven DMaaP Agent
• Extend SDN-R for O-RAN specific YANG-Specs and devicemanagers.

SDN-R Disaggregation means

• Better split regarding performance from the three originations: 1. devices southbound 2. Web users northbound 3. database processing.
• Have one entrypoint for Web User access to different web services of SDN-R: UX Web Service, REST, RESTCONF, Netconf device related
• Use ONAP database components
• SDNC/CCSDK/SDNR Devicemanager cluster/Netconf
  • Provide function to support NETCONF/devicehandling by devicemanagers for one OpenDaylight mountpoint in a cluster.
  • Provider to consuming microservices to publish mountpoint state changes and capabilites of NETCONF/device.  (Used by O-RAN-SC OAM) (model-driven DMaaP Agent)
• Solution integration test covers O-RAN-SC OAM (Operations and Maintenance) Scenarios.
• RPC/bundle for devicemanager configuration service
• SDNR WEB service  is entry point for WEB Browser/Client

Used from CCSDK

• IP V6 .. Web and Server side (Actually moved to Guilin)
• Java 11 (Actually moved to Guilin)
• Use new "Databroker" MDSAL interface

WEB Client

• Data table access via extended odlux db api. See ODLUX DB API
• configApp support Core model 1.4
• connectApp accept IPV6 and DNS names
• NEW aai App

Architecture

• Three node types for wt service: Web service cluster, Devicemanager cluster, DB cluster
• Features are provided by CCSDK/features/sdnr. 
• One SDN-C/SDN-R image. Node types are configured:
  • by configuration parameter: WTSDNR-WEB, WTSDNR-DEVICEMANAGER, WTSDNR-DB
  • El Alto configuration "WTSDNR" not supported anymore
• Server platform (Bold new in Frankfurt):
  • WEB: SDNC/ODL/Karaf: apigateway, odlux, helpserver, dataprovider
  • DEVICEMANAGER SDNC/ODL/Karaf: devicemodel, devicemanager, websocketmanager2 (Discussion: dataprovider as devicemanager DB client service)
  • DB: Alpine + Elasticsearch (ODL/Karaf not nessecary) .. Existing ONAP ES Image if possible.
    • Elasticsearch Version 6.4.3 
    • (docker run -d --name sdnrdb -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --network yaml_default docker.elastic.co/elasticsearch/elasticsearch:6.4.3)
• APIGateway: Add RestConf Forwarding
• DB as a Service
• WS notification forwarding to WEB Service and Client
• Devicemanager disaggregation for multi-technolgy support. (Used for CoreModel 1.4)
  • Goal: Different devicemanager bundles, managing netconf devices. E.g. devicemanager1.2, devicemanager1.4, DevicemanagerPM. 
  • See SDNC-848
  • Selection depends on capabilites provided by hello-answer

  • Create Mountpoint Status Provider:

    • model-driven DMaaP Agent  

    • Provide Notifications via DMaaP

WEB Cluster-DevicemanagerCluster - DB Cluster setup for dev environment and kubernetes

• Each cluster is providing a Kubernetes services
• Service access via DNS Name

Open points

• Cluster internal notification handling
• Configuration 
  • Which configuration for which cluster 
  • How many configuraton files
  • Run-time reconfiguration only via RPC
  • Internal cluster synchronization to be specified.
  • Initial configuration via file
  • Using MDSAL
• Change to to new RESTCONF (Frankfuert/ G...?)
