IntOps, the new model to unlockthe full potential of 5G IntOps and the role of automated continuous testing— A Spirent and Deutsche Telekom Vision Paper IntOps, the new model to unlock the fullpotential of 5G IntOps and the role of automated continuous testing Overview: This vision paper aims to highlight the benefits of IntOps and automated continuous testing for telecommunication providersundergoing the transition to 5G. The paper offers both strategic and tactical insights within a narrative highlighting why thistransition is vital, along with proof-points around the benefits supported by expert input from Deutsche Telekom and Spirentto provide an overview of this innovative evolution. Introduction — Welcome to the 5G era Nowadays customers expect more from theirtelecommunication service providers and over the nextdecades, breakthrough new services such as privateenterprise networks will push both the technology andbusiness models of the operators into uncharted directions.Within this background, it has become recognised byindustry leaders such as Deutsche Telekom that the oldways of building, managing, and upgrading networksmust adapt to the modern realities. By working closelywith leaders within testing and assurance such as Spirent,the future strategy is built on a notion of highly automatedenvironments which underpins a new operating modelable to deliver on the true potential of both 5G andinterconnected telecommunications systems. The telecommunication industry is undergoing the mosttransformative phase in its 200-year history. A transitionin part predicated on adoption of fifth generation mobiletechnology is heralding a massive shift for public, private,and societal use cases. By some analyst estimates, mobileoperators will spend around$1 trillion on 5G infrastructurebetween 2019 and 2025. Unlike earlier generations ofnetwork upgrades, 5G welcomes an opening up of thesupplier ecosystem to embrace software defined networkfunctions that bring with it agility and innovation. Yet, with the arrival of 5G, the shift towards these more opentechnologies, standards, and interfaces brings with it a greatdeal of complexity. Where upgrade and reconfigurationcycles were typically measured in months – today, changescan take place multiple times a week. This in turn requiressoftware that can manage that change and orchestrate theappropriate testing at the applicable stages. With customers dependent on the reliability of mobilenetworks for mission critical use cases, congestion andeven small periods of downtime can lead to significantfinancial penalties and longer lasting reputational damage.Especially as networks are constantly evolving and need tokeep up with features whilst ensuring reliability. VISION PAPER Understanding the Integration Operations (IntOps) model How can an operator rapidly adapt networkfunctions to changing demand and at the sametime ensure end-to-end service quality? To deliver on this vision, Deutsche Telekom has re-inventedhow it runs its operational workflows. This moves awayfrom a legacy approach of a few vendors providinghardware, operating systems, and the software to run onthese platforms – in essence the full vertical stack. Today,for example, different vendors may be providing theunderlying infrastructure or functions of the software-basedarchitecture. The operator then internally needs to integrateand operate a diverse stack of software, hardware, andmanagement elements to gain more control and agility overits environment. Regarding this, consistency is crucial and therefore IntOpsaims to introduce reproducibility in the change processes by: •Modeling software defined network functions in adeclarative way, •Setting up a supply chain for the corresponding softwareassets from the various upstream sources to the differenttarget cloud infrastructure environments, •Establishing a well-defined way of how to customizesoftware network functions so that they reflect theenvironment specific context and From being an Operator managing fixed stacks – DeutscheTelekom is becoming an Integrator and Operator – definedinternally as IntOps and underpinned by establishedmethodologies and technologies such as GitOps as shown infigure 1. IntOps is a major shift in strategy that is underwayat DT and within other industry leaders that recognize thatsystemic change is necessary to meet longer-term goals. •Managing the lifecycle management of all softwareprocess instances via closed-loop automation. Test automation is the required complementary technologyfor ensuring end-to-end service quality for the customers oftelecommunication operators and mandates the need fornew strategies in these complex environments as describedfurther in subsequent sections of this paper. IntOps is not an industry “standard”, but it addresses theflexibility/stability dilemma which every telecommunicationsoperator faces in the context of managing software definednetwork functions: VISION PAPER Continuous Te
