Building a Personal OSS Sandpit

Being Passionate About OSS, I’ve used this blog / site to share this passion with the OSS community. The aim is to evangelise and make operational support tools even more impactful than they already are.

But there’s a big stumbling block – the barrier to entry into the OSS industry is huge. The barrier manifests in the following ways:

  • Opportunities – due to the breadth of knowledge required to be proficient, there aren’t many entry-level, OSS-related roles
  • Knowledge / Information – such is the diversity of knowledge, no single person has expertise across all facets of OSS – facets such as software, large-scale networks, IT infrastructure, business processes, project implementation, etc, etc. Even within OSS, there’s too huge a range of functional capability for anyone to know it all. Similarly, there’s no single repository of information, although organisations like TM Forum do a great job at sharing knowledge. On top of all that, the tech-centric worlds that OSS operate within are constantly evolving and proliferating
  • Access to ToolsOSS / BSS tools tend to be highly flexible, covering all aspects of a telco’s business operations (from sales to design to operations to build). OSS tend to cost a lot and take a long time to build / configure. That means that unless you already work for a telco or an OSS product vendor, you may struggle to get hands-on experience using the tools

It’s long been an ambition to help reduce the third barrier to entry by making personal OSS sandpit environments accessible to anyone with the time and interest.

The plan is to build a step-by-step guide that allows anyone to build their own small-scale OSS sandpit and try out realistic use-cases. The aim is to keep costs to almost nothing to ensure nobody is limited from tackling the project/s.

The building blocks of the sandpit are to be open-source and ideally reflect cutting-edge technologies / architectures. The main building blocks are:

  1. Network – a simulated, multi-domain network that can be configured and tested
  2. Fulfilment / BSS – the ability to create product offerings, take customer orders for those products, then implement as services into a network
  3. Assurance / Real-time – to perform (near) real-time monitoring of the network and services using alarms / performance / telemetry / logging
  4.  Resource / Inventory – to design and store records of multi-domain networks that spans PNI (Physical Network Inventory), LNI (Logical Network Inventory), OSP (Outside Plant), ISP (Inside Plant) and more
  5. Data Visualisation & Management – being able to interact with data generated via the abovementioned building blocks. Interact via search / queries, reports, dashboards, analytics, APIs and other forms of data import / export
