The Value of an Agile Network Edge
Service providers face the daunting tasks of delivering competitive, differentiated services. Today’s data-intensive and latency-sensitive applications demand greater performance. And when it comes to the innovative services of tomorrow, service providers need to adapt quickly to evolving standards.
Existing networks that primarily rely on a consolidated cloud computing and data storage model or on fixed function physical infrastructure are challenged to deliver the cost-effective near-real-time responsiveness required by existing use cases. Over the next few years, these networks will also need to improve scalability to support the rapidly growing number of sensors and devices, estimated to reach 50 billion by 20221, and data volumes, predicted to grow to 175 zettabytes by 20252.
To respond to customer expectations while controlling capital investment and operational cost, network infrastructures need to be transformed to be agile, scalable, and intelligent. Upgraded infrastructure can adjust to meet variable system demands—providing lower latency, improved throughput, and greater reliability—and enable capitalization of every data point in the network, leading to new revenue stream opportunities and insights.
Essential to this modernized infrastructure is combining the power of edge computing with cloud-ready software infrastructure. Optimizing workload placement on shared physical resources can help offer higher returns.
Benefits of Computing at the Network Edge
Placing compute at the network edge makes it possible to intelligently manage workload placement and provides key operational benefits:
- Increased speed and lower latency. Moving data processing and analysis to the edge helps speed system response, enabling faster transactions and better experiences that could be vital in near-real-time applications.
- Improved network traffic management. Minimizing the amount of data sent over the network to the cloud can reduce the bandwidth and costs of transmitting and storing large volumes of data.
- Greater reliability. The amount of data that networks can transmit at one time is limited. For locations with subpar internet connectivity, being able to store and process data at the edge improves reliability when the cloud connection is disrupted.
- Enhanced security features. An edge computing solution may help increase data security by limiting the transmission of data over the internet. In healthcare, for example, there may even be local or regional requirements to limit the storage or transmission of personal data.
- Agility and scalability. With the ability to distribute computing strategically across the network, companies can ensure applications settle in the place of highest value and make the best use of their resources. This opens up a range of opportunities such as establishing new services, targeting service delivery between localized markets, or expanding capacity without the need to open a new data center.
Considerations for the Network Edge
The network edge sits within your network just outside the network core. It includes converging locations such as regional data centers, next generation central offices (NGCOs), fixed wireline access points, wireless access base stations, and radio access networks (RANs). The network edge can also include on-premises locations, such as universal customer premises equipment (uCPE) devices where multiple workloads such as software-defined wide area network (SD-WAN) and enterprise applications can be hosted in a single edge-computing device.
Transformation of the network edge is about system optimization and enabling increased control over traffic management including over how and where to process and transmit data at the data-packet level.
Service providers have already adopted software-defined networking (SDN) and network functions virtualization (NFV) to bring flexibility into their networks, but this approach can be extended further. Adopting cloud-like management practices and implementing a software-defined edge can bring increased operational agility and resource efficiency.
Combining regional fixed and mobile network functions into a new central office, deploying private wireless networks, or ensuring secure enterprise universal customer premises equipment (uCPE) solutions will take a careful balance of performance and agility.
Service providers and industries are taking advantage of Intel® technology and expertise for network edge deployments. Intel helps bring together the products, ecosystem, and expertise to accelerate commercial solutions at the edge.
For example, Verizon partnered with Intel, Samsung, and Wind River to deploy the world’s first fully virtualized end-to-end 5G data session in a commercial network, proving the readiness of virtualized RAN technology.
Intel also helped Lumen (formerly CenturyLink) develop a network that delivers both high performance and power efficiency. Working closely with Intel and using Intel® Xeon® Scalable processors, Lumen has added flexibility to its service delivery by customizing performance within power footprint limits.
