Digital Operations Center for service and network automation

A new breed of service orchestration and service assurance for network slicing

Why CSPs need to evolve to full service and network automation

It’s no secret that consumer value creation possibilities are almost exhausted. To remain relevant and continue to compete, it’s time for communications service providers (CSPs) to offer digital services and turn their attention to vertical markets. Manufacturing, enterprise campuses, smart cities, transportation, logistics, healthcare, and gaming hold new revenue opportunities. Connectivity is a natural entry point to these markets, ABI Research estimates an opportunity, of up to $43 billion, just for network slicing

Your biggest challenge? To realize the opportunity, and unlock the value of your network, you need to offer customer-centric and tailored slice-based services at speed while managing cost and complexity. Operability that traditional network operations approaches fail to deliver.

To support the new way of doing business and to create value for your customers driven by dynamic business needs, you need to evolve your Network Operations Center (NOC) with service and network automation.

The technical imperative for service and network automation

It’s no longer possible to manually manage, assure and operate services at scale and end-to-end over multiple domains, technologies, and vendors. The traditional network operations center (NOC) - and yesterday’s siloed and technology-focused tools and processes - cannot operate the dynamic networks and services of the future.

To support network slicing based services on complex networks, cost-efficiently and at scale - and access the $43 billion opportunity - the operations support system (OSS) and networks themselves need to evolve so CSPs can unlock the value of the network.

Simplification from technology to business focus is required and service and network automation needs to be based on business intent and contracted SLAs.

Introducing a new and comprehensive approach for integrated, end-to-end service lifecycle management

To expose the rich capabilities of your network as consumable services for your customers - and to do this at scale - requires numerous activities like service orchestration, service operations and service assurance. Although these activities are intrinsically related, they have traditionally been separated at the process level and at the tooling level. Going forward, you need to bring these steps together into a single, integrated round-trip set of processes to achieve scale and cost efficiencies.

Our industry refers to this as "managing the service lifecycle" and it has never been more important that these steps within the lifecycle are tightly integrated. We see two important developments that can be leveraged:

  1. Virtualization techniques have made 5G-era networks much more complex and as we move toward more disaggregated architectures, this complexity will continue. But these virtualized networks and disaggregated architectures are software- driven and therefore programmable.
  2. This programmability is what enables automation. And automated service lifecycle management is the mandate for successful cost efficiencies at scale in the 5G era

We see this as a stepwise evolution, not a “big-bang” that needs to happen all at once. We visualize this below. The traditionally separated OSS fulfillment and OSS service assurance processes move from left to right over time to eventually become fully integrated with the addition of service orchestration capabilities. We see steps along the way that deliver tactical returns while supporting the left-to-right movement are proving to be a successful strategy within the marketplace.

Understanding customer-centric automated operations

As we move toward this integrated service lifecycle approach, the atomic functions for service orchestration and service assurance based upon a common data model become integrated steps in a single round-trip.

What is service orchestration?

Service orchestration sets the policies and methods for connections made through the network and delivers the commercial services and their related Service Level Agreement (SLA) assurances.

In 5G-era networks, service orchestration needs to be intent-based to enable your clients to request digital services and network slices in business terms to reduce friction in B2B commerce.

The service orchestration system sits between the commercial layer at top and the underlying network beneath. It abstracts the network complexity to expose capabilities in business terms. It provides the interface to the service order management process and it choreographs the construction of services across the network domains. This provides the interface to network orchestration systems that carry out the necessary steps within the respective network domains to support the end-to-end services.

5G-era networks are increasingly complex, and this automated flow between the service orchestrator and the underlying network orchestrators is necessary to ensure accuracy, consistency and pace of managing the service lifecycle at scale.

What is service assurance?

Service assurance manages the adherence to criteria that have been set for the networks and services. These include:

  • External criteria such as SLAs that bind the CSP to agreed commercial terms with their customers
  • Internal criteria such as performance, availability, and reliability that the CSP has set for itself to meet

These external and internal criteria are defined within the service assurance system to set the measurement benchmarks based on business intent. Modern service assurance systems share common modeling and policies that are set during the service design phase to ensure the ability to meet the requirements.

To support the complexity of 5G-era networks, the network and service assurance processes must seamlessly interoperate. This is necessary to ensure the hierarchical alignment of the network layer, the service layer and the customer layer in order to set operational prioritizations.

Why is unified inventory critical for network automation?

For CSPs to achieve service and network automation, there must be a trust and reliance upon data including the currency of the data in near real-time.

According to Appledore Research, with evolved virtualized and containerized networks, there are hundred-fold increases in operational actions and the round-trip process to design, deploy and assure services must be automated to work at scale. This begins with the discovery and reconciliation of services and the resources that comprise the services and the constant near real-time synchronization with these.

The logical inventory must be based upon modern processing techniques to ensure the read/write refresh rates that guarantee data confidence can be trusted to base automated actions upon.

A unified inventory capability therefore provides a common data plane that is the foundation for automated service orchestration and service assurance functions.

Service orchestration and service assurance for network slicing use cases

Network slicing is an important technological development that CSPs look to capitalize on. It provides a way to offer differentiated services with guaranteed quality of service across common network infrastructure. This is much more efficient than previous techniques to “nail up” or dedicate infrastructure resources to support differentiated service requirements.

Various industry organizations have contributed toward standards that ensure that CSPs can avoid vendor and technology lock-in as they architect their approach to network slicing.

CSPs will not employ network slicing for all services they offer. But for those services that they do, CSPs will need to automate the process to design, deploy and assure network slices to be cost effective and ensure they meet contracted SLAs. The complexity and dynamic nature of network slice-based services is far too complex to leave to manual operations.

Further, CSPs need to be able to abstract the network complexity, and expose the network slices to the market, in order to let business customers flexibly and easily subscribe to a slice, configure the SLAs based on the needs of their customers in support of new business models (B2B2x).

Network slicing – originally a 5G mobile networking concept -- has extended beyond that scope. Effective network slicing operations platforms must enable CSPs to leverage all their network infrastructure investments across the various domains of access, transport, core and cloud.

One important example of the evolving scope of network slicing is the concept of 4G/5G network slicing. Nokia introduced this technical innovation in early 2020 as a way for CSPs to begin their adoption of network slicing with their existing broad coverage of 4G networks while they ramp-up their 5G deployments. Other examples of the extending scope of network slicing include things like Fixed Wireless Access services and transport networks as services.
