Edge Compute: A Limited Resource DrivesEfficiencyCompute power at the edge is in increasingly high demandbut unlike a data center with easy access to additionalcompute, it is a limited resource that must be allocatedthoughtfully. For illustrative purposes, if an MNO decided todeploy multiple cells of a 200Mhz 64T64R massive MIMORAN deployment on a 4thGen Intel® Xeon® Scalable-based32 core server, each core used for software infrastructurereduces the number of cores available for commercializationheadroom and feature growth by 8.33%.In this scenario, if the MNO considers L1, L2, OAM/fronthaulas relatively fixed and consuming 20 cores, this leaves 12 opencores. With Wind River Studio Cloud Platform, the MNO canconsume as little as a single core for CAAS, leaving 11 (92%)to utilize to increase the capacity per cell site, including:•Increasing the number of users served.•Increasing the throughput or data speeds for existing users.Benefits of CAAS Optimization1 CoreNon-Optimized CAAS4-6 Cores20 Cores for L1, L2,OAM, FronthaulExample: 200Mhz x 3Cells of mMIMO working on a 4thGen Intel Xeon based 32 Core Server12 coresremaining+Figure 1.Illustration of benefit of Wind River Studio's reduced compute footprint.Wind River Studio Delivers Efficient DistributedCloud OperationsWind River Studio is the first cloud-native software for thedevelopment, deployment, operation, and servicing of ORAN/vRAN systems. The software also works with other mission-critical intelligent edge systems that require security, safety,and reliability to execute on a single core (with 4thGen Intel®Xeon® Scalable processor-based servers). Wind River Studiois architected to deliver digital scale across the full lifecyclethrough a single pane of glass to accelerate transformativebusiness outcomes. •Reducing additional hardware cost and power consumptionby adding new applications such as a vRouter to the sameserver.In terms of feature growth, the extra core capacity allowsOEMs/RAN vendors to add new features without needingadditional servers or optimizations.In contrast, with this same scenario, a non-optimized CAASsolution that requires 4-6 cores reduces access to computepower by between 33%-50%.As seen in Figure 1, with Wind River Studio, less computepower is needed to deliver more capacity with higherperformance. The remaining compute power can be used foradditional capacity, feature growth, and/or new revenuegenerating services, simultaneously reducing overhead andincreasing revenue opportunities. These improvements areseen in tests of a demonstration platform that are documentedin this paper (see tests details below and server specificationsin Table 1).92% of cores for value-add (capacity, feature growth)50-67% cores for value-addWind River Studio delivers an integrated cloud platform thatunifies infrastructure, orchestration, and analytics capabilities.This platform enables mobile network operators (MNOs) todeploy and manage globally distributed 5G edge networks,including remote servers that process vRAN traffic. The corecapabilities of Wind River Studio include:Cloud Platform:A carrier-grade Kubernetes cloud platformfor managing distributed cloud infrastructure. Based on theopen source StarlingX project, Wind River Studio compilesoptimal open-source technology to deploy and managedistributed networks. Conductor:Comprehensive orchestration and automationcapabilities provide one platform to achieve multi-cloudautomation and zero-touch operation. MNOs can use the appcatalog to select applications, deploy them to a carrier-gradecloud platform, and orchestrate the resources needed for theapplications at the edge network site. This orchestration allowsscalability from a handful of nodes to thousands of nodes in ageographically dispersed, distributed environment.Analytics:Using machine learning algorithms, Wind RiverStudio supports effective management of a distributed cloudsystem by consuming and processing data and producingmeaningful insights for decision making.
