How Digital Service Lifecycle Management Delivers Speed, Configurability and Accuracy

Comptel participated in several partner showcases during last week’s TM Forum Live! 2016 in Nice, France, with one in particular reimagining the model of digital service delivery for the modern B2B and B2C customer.

As Comptel CTO Simon Osborne explained, Comptel partnered with IBM and Juniper Networks in an IBM Cloud-Based Networking architecture. The project introduces new strategies for leveraging software-defined networks (SDN) and network functions virtualisation. As a result, operators can efficiently automate and reconfigure parts of their network to enable automated, self-service digital service delivery. As part of the partnership, we’re contributing our Digital Service Lifecycle Management (DSLM) model, technology and expertise.

Digital Service Lifecycle Management (DSLM) architecture

In an earlier blog, I explained why this needs to happen. B2B and B2C customers today want personalisation, convenience and instant gratification in the purchasing process. Operators need to evolve their infrastructure to deliver better customer experiences to stay competitive, and network virtualisation gives operators the agility and flexibility they need to do so.

The key to introducing new capabilities gradually – since complete network overhauls aren’t practical for most operators – is to introduce “islands” of NFV capabilities into the network. On top of that, fresh approaches to managing the interconnection between physical and virtual resources will ensure operators can achieve this agility quickly, and at minimal cost.

In this post, I’ll explain just how you do that.

What is Digital Service Lifecycle Management

Comptel first introduced DSLM in our white paper – Digital Service Lifecycle Management: How CSPs Can Play a Successful Role in the Digital Economy. As Heavy Reading analyst Caroline Chappell wrote, operators today face competition from cloud-born companies like Google and Amazon, which have the infrastructure flexibility to spin up attractive new digital services much faster than the average operator.

Portraying the future role of operators as aggregators of digital services (from which the average consumer and business could buy whatever services they need to fill out their “personal digital ecosystems”), Chappell said network evolution is required to enable “on-demand personalised service creation.”

Digital Service Lifecycle Management (DSLM) layers

DSLM is how you evolve the network. It’s the middle portion of a three-tiered system that decides how virtual and physical network resources are managed to support service requests from front office systems.

How the Three-Tiered DSLM Model Works

This NFV-driven model requires three layers: one for resource management, one for digital service lifecycle management and one for business management.

The customer only ever sees the business management layer, which sits at the top and comprises the shopping environment, order configuration and payment tools. Customers configure and purchase services available through a digital catalogue, and automated ordering and billing capabilities ensure customer requests are quickly passed on for configuration and fulfillment.

The middle digital service lifecycle layer manages service composition through the service orchestration tool and the digital service catalogue. At this level, each new customer order is automatically checked for feasibility and availability, based on digital service definitions, service level agreements and inventory. That improves order quality and eliminates false service availability promises, which cuts down on customer dissatisfaction and the risk of order fallouts.

The resource management layer sits at the bottom and includes the infrastructure management tools and controllers that support physical and virtual network functions. When a customer inquiry for a new digital service arrives, this layer determines how best to deploy resources to fulfil that request.

With this NFV-driven model, operators can offer B2C and B2B customers alike a fast, accurate and automated, self-service buying experience. The digital catalogue can be scaled to include any new service, from your standard consumer or business IT and communications services, to network functionality, to IoT connectivity, to third-party SaaS solutions. That means operators can add to their capabilities as the digital economy grows and consumer demand evolves.

Where DSLM Fits in to IBM’s Cloud-Based Network

We brought our DSLM model to the IBM partnership, and it’s supported by FLOWONE, our service orchestration solution. Sitting in the middle between IBM’s Omni-channel Customer Engagement, and on top of a range of resource services and infrastructure tools that include Juniper’s NFV orchestration and infrastructure management solutions, it brings our vision for NFV-based fulfillment to reality.

The IBM Cloud-based Networking architecture was introduced recently at TM Forum’s Live! event but you can read more in the IBM Blog by Steven Teitzel, Telco Global Solution Exec – Network Transformation, IBM.

We invite you to visit Comptel at the Light Reading Big Communications Event in Austin 24-25^th May to learn more about the Comptel model for dynamic digital service lifecycle management.
