TRANSFORMING OPTICAL TRANSPORT DELIVERY: A new approach from Nokia to bring capacity to the consumer

O ptical services have been around for some time demand for them is increasing, with higher connectivity, cloud, IoT, 5G and stricter SLA’s to support. The problem is however, accessing bandwidth from the optical network and getting it to the end customers. With the advent of network slicing, it’s not just a case of connecting the end user to the network, there can be several other players involved in the capacity supply chain and a variety of scenarios. For example, a network operator might sell optical capacity to a wholesale reseller, or a business might want to allocate capacity to internal business units or sell some of it on to customers. This could involve several layers of hierarchy, which could be an internal hierarchy or network supporting many divisions within a large tier-1 operator which in turn resells capacity up the chain to the end customer or just to a wholesale provider. Connections, “Starting from the physical core network, if an operator is selling to wholesaler customers or internal business units, first they virtualise it, then they give each one of those layers Scott Larrigan, senior marketing manager at Nokia, told Optical

Following the launch of its PSE-3 chip earlier this year, Nokia recently debuted WaveSuite, a collection of software, apps and tools aimed at transforming the way capacity transport services are delivered, consumed and monitored. Peter Dykes takes a look behind the scenes.

an independent slice of the network. That’s not new, we do that all the time. We’re going to do it much faster now, but we’re also going to add this notion of hierarchy to get to the end customer faster. [Currently,] these value-added resellers or internal business services organisations within the infrastructure company cannot take a slice of the virtual network and pass it up the chain as a network or a service offer, so this is a new service.” He added, “What we’ve done is we’ve introduced open software applications that look at the relationship between the optical network operator, the end customer and everyone in between. We’ve looked at how can we streamline the process of getting bandwidth from

the network into the hands of value- added resellers, systems integrators, internal business services and to the end customer quickly.” In 2019, Nokia plans to add new apps to WaveSuite which exploit the streaming telemetry interfaces, and which are aimed at taking advantage of its PSE3 probabilistic constellation hardware although being open apps means that they can be used on any network and not just in the PSE context. The health and analytics app looks at analogue and digital KPI’s and visualises them for baseline behaviour and anomalies, and uses machine learning. The optimiser app, when used with probabilistic constellation shaping, continually optimises up the chain to

the only thing anyone at any point in the chain can see are their own customers
