SDN NFV WORLD CONGRESS, 2018 – THE HAGUE
Brian Naughton, CTO, presenting on Applying DevOps to the Modern Service Factory.
How do we have a predictable cookie-cut way of delivering and maintaining services so that the costs are under control, but predictable?
“Intent based orchestration is similar to how a sat nav works. Rather than programming all of the lifecycles that bring the service into being, then programming the lifecycles that heal it, change it, optimise it, or move things around for cost and quality reasons, operators need an engine that removes that operational burden from Design and Engineering in order to scale. The intent engine means you can tell it what state you want a service in and it will automatically figure out how to get that service from A to B, taking into account whatever the state of the environment is.”
“Accanto’s focus are the operational NFV use cases. The complicated pieces that an operator would normally throw people at. How does an operator automate after they’ve turned on a service, not just a VNF? If something breaks, or we want to change the shape of that service normally an army of people would be thrown at it. We want to add a whole level of automation to that ‘service’ lifecycle.”
“Level 1 and level 2 people within an operator, who are looking at trouble ticketing or looking at an appliance state, will have to disappear due to the new complexity of a virtual network. In our world, support becomes something that is embedded in the engineering process. The lower cost operating model is required in order to bring NFV to market.”
“Given that NFV is either software programmable or delivered as a lump of software the level of automation that we should be able to achieve in this next version of the service factory, should be greater than anything we’ve been able to achieve in the past.”

Victor Donselaar, VP Sales, presenting on Lights Out Operations for NFV.
Lights out operations is about running your complex network services with close to 100% automation.
“ETSI state that a VNF typically has 13 different lifecycles. So, when an operator moves from a physical to a virtual world, they have to consider 13x more lifecycles. Basic lifecycles i.e. start, stop, etc are centred at the point of on-boarding and mapped to VNF specific device commands making them quite easy to program. However, the more advanced scale, heal, amend, upgrade commands etc, are more difficult to program because logic has to be applied to take into account multiple scenarios and policies. Then take into account the lifecycle of the service itself, which also has to be managed. Manual programming isn’t an option and traditional OSS tools won’t work.”
“Our focus has been on reducing the manual effort involved in launching and running services and we believe we can achieve a 30% reduction.”
“How will an operator scale when these multiple virtual services and all of the associated lifecycles kick in?”
“There are 3 steps to NFV operational automation. Number 1 is Intent driven orchestration, automating most of the lifecycles once the services are in production. Number 2 is reducing operational errors with Behaviour Driven Testing, testing all of the lifecycles before the service goes into production. The third step, having achieved a significant amount of automation with the first two steps, is with AI. Using artificial intelligence to apply diagnostics to uncover any problems that might not have been addressed previously.”
