This document outlines the steps to deploy SDN-Enabled Broadband Access (SEBA) for Telco Appliance.  With the exception of the installation of the SEBA application components (VOLTHA, NEM, ONOS), the installation process follows that of REC (REC Installation Guide).  The production deployment of SEBA is intended to be done using the Akraino Regional Controller, but , for evaluation purposes, it is possible to deploy this release focuses on deploying SEBA without the Regional Controller.In a Regional Controller based deployment, the Regional Controller API will be used to upload the SEBA Blueprint YAML (for Akraino Release 2, SEBA blueprint reuses REC_blueprint.yaml available from the SEBA repository) which informs the Regional Controller of where to obtain the SEBA ISO images, the SEBA workflows (executable code for creating, modifying and deleting SEBA sites) and the SEBA remote installer component (a container image which will be instantiated by the create workflow and which will then invoke the SEBA Deployer (which is located in the ISO DVD disc image file) which conducts the rest of the installation  Instructions on how to deploy the SEBA blueprint using the Regional Controller will be covered in a future release.

The instructions below skip most of this and directly invoke the SEBA Deployer from the BMC, iLO or iDRAC of a physical server. The basic workflow of the SEBA deployer is to copy a base image to the first controller in the cluster and then read the contents of a configuration file (typically called user_config.yaml) to deploy the base OS and all additional software to the rest of the nodes in the cluster.

An overview and diagram of the network connectivity is available on the Radio Edge Cloud Validation Lab page.

Pre-Installation Requirements for SEBA Cluster

...

The user_config.yaml file contains details for your SEBA cluster such as required network CIDRs, usernames, passwords, DNS and NTP server ip addresses, etc.  The SEBA configuration is flexible, but there are dependencies: e.g., using DPDK requires a networking profile with ovs-dpdk type, a performance profile with CPU pinning & hugepages and performance profile links on the compute node(s).  All values in the user_config.yaml should be updated to match the environment for your deployment.

The following link points to the latest user_config template with descriptions and examples for every available parameter:

  user_config.yaml template


Note

Note: the version number listed in the user_config.yaml needs to follow closely the version from the template. There is a strict version checking during deployment for the first two part of the version number. The following rules apply to the yaml's version parameter:

### Version numbering:
###    X.0.0
###        - Major structural changes compared to the previous version.
###        - Requires all users to update their user configuration to
###          the new template
###    a.X.0
###        - Significant changes in the template within current structure
###          (e.g. new mandatory attributes)
###        - Requires all users to update their user configuration according
###          to the new template (e.g. add new mandatory attributes)
###    a.b.X
###        - Minor changes in template (e.g. new optional attributes or
###          changes in possible values, value ranges or default values)
###        - Backwards compatible
