Red Hat and Intel technologies for modern 5G networks

The promise and challenge of 5G network infrastructure

5G technology is bringing a new era of innovation and possibilities to the telecommunications industry with high speeds, low latency, and new application delivery models. As a business platform, 5G can unlock considerable value for consumers and enterprises alike. Yet for all the promise of this new technology, communications service providers (CSPs) must modernize their infrastructure to fully realize 5G benefits and keep pace with an increasingly data-centric world.

Everything from core and edge networks to operations support systems (OSS) and business support systems (BSS) is ripe for modernization.1 Fully modernized infrastructure will allow CSPs to extend beyond network services to offer new workload-optimized application services, elastic data services, and dynamic service packages. Those that embrace this unprecedented business transformation will realize new, more reliable revenue streams, tightly integrate with their enterprise customers, and derive more value from their own data.

Unlike legacy telecommunications networks that are largely proprietary and vertically integrated, 5G unlocks highly automated and innovation-driven, service-based architecture. Designed as a fundamentally cloud-native technology, 5G is implemented in virtualized software layers on industry-standard servers—spanning from the core to the edge of the network. Along with high bandwidth and low latency, capabilities like network slicing and prioritization will foster new use cases such as high-capacity ingest, virtual cinema, geospatial video surveillance, telemedicine, remote surgeries, and augmented and virtual reality experiences.

Edge computing is particularly important in a 5G world. The combination of edge computing with 5G speeds and low latency is already supporting new applications and use cases. Moving compute and analytics resources closer to the points where data is generated saves valuable time and keeps large amounts of traffic off of public cloud networks. New telecommunications cloud models are emerging with large numbers of smaller interoperable clouds that will interact with public clouds. Establishing these new cloud networks represents considerable opportunity for carriers and CSPs.

As CSPs transform their business from traditional telco services toward becoming a modern provider of digital services, they must digitize their own internal business systems. Along this path they face multiple challenges, including:

  • Transitioning from virtual machines (VMs) to containers to support virtual network functions (VNFs), cloud-native functions (CNFs), and microservices.
  • Embracing Kubernetes container orchestration technology along with end-to-end data services for hybrid cloud computing.
  • Integrating across hybrid multicloud infrastructure in a cost-effective fashion.
  • Employing specialized compute, storage, and network hardware to accelerate and optimize key customer and internal workloads.
  • Overcoming the perceived risks of moving from proprietary infrastructure to deploying on an open platform.
  • Automating all aspects of their business, including call centers and network operations.
  • Managing customer data and respecting regulatory requirements.
  • Harnessing the power of artificial intelligence and machine learning (AI/ML) to place data at the heart of the business operations.
  • Monetizing the edge while creating more business value for enterprise customers.
  • Ensuring their business can integrate seamlessly with the broader digital value chain (e.g., expose their value through APIs in order to foster agile business partnerships with cloud service providers).
  • Forging a long-term technology strategy and the right vendor partnerships to facilitate the transformation journey and ensure an effective outcome.

Red Hat and Intel technology for modern infrastructure

Given the wide-ranging impacts of 5G, most CSPs need to modernize infrastructure across their organization. Red Hat and Intel technology lets organizations achieve diverse modernization efforts based on a common open platform, reducing risk and accelerating infrastructure roll-outs.

Modernization at the network edge for low latency

Some of the most promising 5G applications depend directly on extremely low latency. Self-driving cars and virtual and augmented reality require response times in the tens of milliseconds. Many Internet of Things (IoT) applications likewise have safety and quality control implications that are highly dependent on very low latency. Hosting these applications in a centralized cloud may ultimately render them non-viable. Edge computing and modernized 5G infrastructure are key to the success of these and other initiatives.

To reduce latency, service providers are increasingly looking to edge computing to process workloads and analyze data closer to end-user devices.2 There is more network bandwidth available at the edge of the network, and latency is lower the closer to the user device or data collection point the workload can be deployed. Given their close proximity to client devices, service providers have a unique opportunity in deploying edge computing resources. 

With 5G network infrastructure built on industry-standard servers with software-defined networking and data services, the compute, storage, and network scalability of those platforms is essential to guarantee sufficient application performance. Intel Xeon Scalable processors benefit from decades of innovation in support of customers' most demanding workloads. With a balanced architecture, these processors are optimized for many workload types and performance levels including cloud, enterprise, high-performance computing (HPC), network, security, and IoT. With a wide range of powerful cores and multiple frequency, feature, and power levels, Intel Xeon Scalable processors are ideal for systems that serve both edge and core workloads.

Intel Optane persistent memory is optimized for and designed to work with the latest 2nd Generation Intel Xeon Scalable processors. One Intel Optane persistent memory per channel is supported, providing up to 3 TiB of Intel Optane persistent memory on a single socket. An eight-socket system built with Intel Xeon Scalable processors could access up to 24 TiB of system memory. This combination of hardware components represents engineering across the hardware stack that delivers higher performance and capacity.

Intel Xeon Scalable processors offer a balanced architecture for many types of workloads and performance levels, that let you place your workloads securely where they perform best—from the edge to the core.

Modernizing the core network to support advanced functions and flexibility

For most networks, 5G adoption represents an evolution. Many providers currently implement 5G using their existing 4G network as a stopgap. While this approach accomplishes 5G connectivity, older infrastructure imposes limitations in terms of both speed and flexibility. 5G SA realizes the ultra-low latency of 5G by operating with a true 5G core. Yet many telecommunication companies are anxious that CNFs will not work consistently in the core network environment.

Red Hat and Intel solutions combine silicon expertise with software innovation. Intel provides best-in-class silicon and platform innovation for the wireless core. Red Hat OpenShift brings strong orchestration, performance, and resource management. CNFs can be managed on top of Red Hat OpenShift throughout their life cycle, bringing security, simplicity, and scalability. Importantly, Red Hat and Intel’s test beds certify CNFs before putting them out to market, reducing risks and increasing operational efficiency. A vibrant ISV ecosystem supported by certification provides confidence in a cloud-native 5G SA core.

Modernize software-defined data services with Red Hat Data Foundation

Data services are a critical component of cloud-native infrastructure since applications need data services that are available across the hybrid cloud. Many telecommunications networks currently implement NFV using OpenStack, and software-defined Ceph storage is consistently the most popular OpenStack storage solution.3 Because OpenShift Data Foundation uses Ceph as its data storage layer, it represents an ideal migration path for those with existing Ceph or Red Hat Ceph® Storage clusters. CSPs can experiment with container-based applications without having to migrate their data.

OpenShift Data Foundation offers two modes of storage to accommodate the broadest range of applications. Traditional internal-mode storage schedules applications and OpenShift Data Foundation pods on the same Red Hat OpenShift cluster, offering simplified management, deployment speed, and agility. Pods can either be converged onto the same nodes or disaggregated on different nodes, allowing organizations to balance compute and storage resources. External mode, in contrast, supports mixed media and also decouples storage from Red Hat OpenShift clusters, allowing multiple Red Hat OpenShift clusters to consume storage from a single, external storage cluster.4

Engineered as the data and storage services platform for Red Hat OpenShift, Red Hat OpenShift Data Foundation is software-defined storage for containers.

Intel Optane Solid State Drive (SSD) technology is critical for optimizing performance for different workloads running on OpenShift Data Foundation. Intel Optane SSDs can offload and accelerate the Ceph metadata cache to accelerate application performance and also increase the performance of the Kubernetes etcd database. The SSDs take the write pressure off of the Ceph storage media, creating a solution that is optimized for both input/output (I/O) operations per second (IOPS) and total cost. Featuring a memory-like capability inside an SSD form factor, Intel Optane SSDs are fundamentally different from other SSDs. This design gives them lower latency, higher IOPS performance, and greater endurance. For example, Intel Optane SSDs support an industry-leading 100 drive writes per day (DWPD).5 

Rapidly scaling and optimizing data services for specific workloads

Modern telecommunications services serve a multidimensional role in consumers' lives, touching everything from financial services to healthcare to entertainment and education. At the same time, telecommunications providers are making significant investments in new digital services to stay competitive and benefit from new revenue streams. These parallel trends are resulting in massive data growth inside telecommunications networks.

To simplify data services scalability, Intel offers workload-optimized data node configurations for OpenShift Data Foundation. Based on Intel Xeon Scalable processors, Intel Optane technology, and Intel Ethernet technology, the data node configurations offer a range of choices. Intel data nodes for Red Hat OpenShift are powered by OpenShift Data Foundation Advanced Edition. Telecommunications providers can efficiently procure and deploy the appropriate data nodes from their favorite vendor for specific workloads, including:

  • Data nodes optimized for edge infrastructure.
  • Data nodes optimized for capacity. 
  • Data nodes optimized for I/O performance.

Modernizing and scaling operations and business support systems (OSS/BSS)

As telecommunications companies become more data centric, their operations support systems (OSS) and business support systems (BSS) are receiving increasing focus. Typically implemented as large in-memory databases, these systems are large and growing. Not only must they operate at peak performance as they scale to accommodate more customers, but the data stored in them represents a vital source of innovation.

AI and ML are increasingly used to derive new insights from the vital business and customer data in these systems. Service consumption can be tracked in real time, with emerging trends identified proactively. Organizations can also identify their highest value customers, offering timely personalized communications and offerings based on customers’ historic use of telecommunications services.

BSS systems can greatly benefit by taking advantage of latency reductions enabled by Intel Optane Persistent Memory (PMem). Intel Optane PMem provides a unique combination of affordable larger capacity and support for data persistence. It combines byte-addressability similar to dynamic random-access memory (DRAM) with optional persistence similar to storage. Intel Optane PMem offers two distinct operating modes: Memory Mode and App Direct Mode. Memory Mode behaves exactly like traditional, volatile (nonpersistent) system memory at lower cost, enabling higher capacities within a constant system budget. Modules are available in capacities of 128GB, 256GB, and 512GB. 

Refreshing OSS and BSS systems with the latest Intel Xeon Scalable processors and adding memory capacity with Intel Optane PMem can make a real difference for large in-memory database systems and analytics while lowering costs over systems equipped with DRAM alone.
