Hyperscalersand ecosystem stakeholders are investing tens of billions of dollars intometaverses, high quality video, AR/VR headsets, haptic feedback, andvoice controls, as they aim to continually level up gamer experiences.These advancements represent near-term revenue opportunities at atime when cloud, edge, and 5G network ROI has been challenged. Already, gaming adoption has balloonedto more than 100 million users. The globalgaming industry is projected to be worth$321B by 2026, according to PwC’sGlobalEntertainment and Media Outlook 2022-261.Gamers are demanding more bandwidth,engaging from consoles, mobile devices, andnew device platforms. The size and scale ofthis opportunity leaves little room for error. While safety is not on the line, bad networkperformance that degrades gameplay qualityis a non-starter that impacts the viability of thisrobust economic model. Gamers are passionate,vocal, and often, unforgiving. If a platformdoesn’t perform, word travels fast and revenuesare put at risk. Reputation is everything and it isearned by delivering flawless performance thatrespects the loyalty of users. This is easier said than done. Networkchallenges are the most formidable foegamers face. They crop up in the form ofvariable latency issues, long frame responsetimes, lack of availability, slow uploadrates, and poor video quality. With theright testing approach, they can beanticipated and conquered. Autonomous cars, remote surgery, and otheremerging high-profile and critical use casesthat provide essential functionalities, andprecise and instantaneous accuracy havebecome synonymous with stringent networkrequirements. Many industry experts seethe proven ability to deliver reliable gamingperformance as a forerunner to supportingthese critically essential services. This eBook explores the impacts of evolvinggaming requirements on new networks andcloud implementations with a focus on testingstrategies that can be implemented to fosterand empower gaming’s bright future. Gaming Puts Pressure on Cloud and Network Performance Gaming is a leading-edge use case for next-gen networks expected toprovide a foundation for high-performance platforms that must supporta wealth of applications, all varying in functionality and requirements.Eventually, the same performance enhancements networks make forgaming will be used to serve use cases spanning telemedicine,connected vehicles, and beyond. The result is a staggering increase in datatraversing networks as high data processingrates and ultra-low latency response timesemerge as the most coveted new currency.Users expect 20ms response times and thinknothing of demanding hundreds of Mbpsuploads and downloads, all while demandingzero performance disruptions. What’s driving these elevated requirements? Unprecedentedprocessing feats.Scenes are beingenhanced with highdynamic range (HDR)renderings.

New platforms.Powerful new devicesare unleashing high-quality VoIP, 4K video,and dual 8K displayresolution with burstymedia sub-channelslike embedded voiceand video bringing QoErequirements. Network providers have identified dataprocessing, network latency, and jitterchallenges to be the most pressing as theytake steps to meet demand. Why Gaming Hyperclouds NeedAI for Dynamic Scalability CONQUERING GAMING CHALLENGES The real-time sourcing and rendering ofgame scenes are usually handled by graphicsprocessing units (GPUs) located in cloud-based GPU farms, which may contain tensof thousands of individual GPUs. The dataprocessing workloads are shared between theuser’s console and these cloud-based units forfluid and responsive gameplay. Scenes are now more vibrant and realistic asa result of features like high dynamic range(HDR) rendering. This comes at a price fornetworks as: Data processing requirements Online gaming relies heavily on seamlessrendering, visualization, and manipulation of3D images. The realism of these images andthe speed at which they are processed play akey role in creating immersiveuser experiences. •Frame ratescapturing consecutiveimages per second, have reached 60fps through a
