How Secure is Your 5G Network?
By Bill Hagerstrand, Security Solutions BU, Marvell
New Challenges and Solutions in an Open, Disaggregated Cloud-Native World
Time to grab a cup of coffee, as I describe how the transition towards open, disaggregated, and virtualized networks – also known as cloud-native 5G – has created new challenges in an already-heightened 4G-5G security environment.
5G networks move, process and store an ever-increasing amount of sensitive data as a result of faster connection speeds, mission-critical nature of new enterprise, industrial and edge computing/AI applications, and the proliferation of 5G-connected IoT devices and data centers. At the same time, evolving architectures are creating new security threat vectors. The opening of the 5G network edge is driven by O-RAN standards, which disaggregates the radio units (RU), front-haul, mid-haul, and distributed units (DU). Virtualization of the 5G network further disaggregates hardware and software and introduces commodity servers with open-source software running in virtual machines (VM’s) or containers from the DU to the core network.
As a result, these factors have necessitated improvements in 5G security standards that include additional protocols and new security features. But these measures alone, are not enough to secure the 5G network in the cloud-native and quantum computing era. This blog details the growing need for cloud-optimized HSMs (Hardware Security Modules) and their many critical 5G use cases from the device to the core network.

The Three Things Next-Generation Data Centers Need from Networking
By Amit Sanyal, Senior Director, Product Marketing, Marvell
Data centers are arguably the most important buildings in the world. Virtually everything we do—from ordinary business transactions to keeping in touch with relatives and friends—is accomplished, or at least assisted, by racks of equipment in large, low-slung facilities.
And whether they know it or not, your family and friends are causing data center operators to spend more money. But it’s for a good cause: it allows your family and friends (and you) to continue their voracious consumption, purchasing and sharing of every kind of content—via the cloud.
Of course, it’s not only the personal habits of your family and friends that are causing operators to spend. The enterprise is equally responsible. They’re collecting data like never before, storing it in data lakes and applying analytics and machine learning tools—both to improve user experience, via recommendations, for example, and to process and analyze that data for economic gain. This is on top of the relentless, expanding adoption of cloud services.

Network Visibility in Industrial Networks Using Time-Sensitive Networking
By Zvi Shmilovici Leib, Distinguished Engineer, Marvell
Industry 4.0 is redefining how industrial networks behave and how they are operated. Industrial networks are mission-critical by nature and have always required timely delivery and deterministic behavior. With Industry 4.0, these networks are becoming artificial intelligence-based, automated and self-healing, as well. As part of this evolution, industrial networks are experiencing the convergence of two previously independent networks: information technology (IT) and operational technology (OT). Time Sensitive Networking (TSN) is facilitating this convergence by enabling the use of Ethernet standards-based deterministic latency to address the needs of both the IT and OT realms.
However, the transition to TSN brings new challenges and requires fresh solutions for industrial network visibility. In this blog, we will focus on the ways in which visibility tools are evolving to address the needs of both IT managers and those who operate the new time-sensitive networks.
Why do we need visibility tools in industrial networks?
Networks are at the heart of the industry 4.0 revolution, ensuring nonstop industrial automation operation. These industrial networks operate 24/7, frequently in remote locations with minimal human presence. The primary users of the industrial network are not humans but, rather, machines that cannot “open tickets.” And, of course, these machines are even more diverse than their human analogs. Each application and each type of machine can be considered a unique user, with different needs and different network “expectations.”

TSN and Prestera DX1500: A Bridge Across the IT/OT Divide
By Reza Eltejaein, Director, Product Marketing, Marvell
Manufacturers, power utilities and other industrial companies stand to gain the most in digital transformation. Manufacturing and construction industries account for 37 percent of total energy used globally*, for instance, more than any other sector. By fine-tuning operations with AI, some manufacturers can reduce carbon emission by up to 20 percent and save millions of dollars in the process.
Industry, however, remains relatively un-digitized and gaps often exist between operational technology – the robots, furnaces and other equipment on factory floors—and the servers and storage systems that make up a company’s IT footprint. Without that linkage, organizations can’t take advantage of Industrial Internet of Things (IIoT) technologies, also referred to as Industry 4.0. Of the 232.6 million pieces of fixed industrial equipment installed in 2020, only 10 percent were IIoT-enabled.
Why the gap? IT often hasn’t been good enough. Plants operate on exacting specifications. Engineers and plant managers need a “live” picture of operations with continual updates on temperature, pressure, power consumption and other variables from hundreds, if not thousands, of devices. Dropped, corrupted or mis-transmitted data can lead to unanticipated downtime—a $50 billion year problem—as well as injuries, blackouts, and even explosions.
To date, getting around these problems has required industrial applications to build around proprietary standards and/or complex component sets. These systems work—and work well—but they are largely cut off from the digital transformation unfolding outside the factory walls.
The new Prestera® DX1500 switch family is aimed squarely at bridging this divide, with Marvell extending its modern borderless enterprise offering into industrial applications. Based on the IEEE 802.1AS-2020 standard for Time-Sensitive Networking (TSN), Prestera DX1500 combines the performance requirements of industry with the economies of scale and pace of innovation of standards-based Ethernet technology. Additionally, we integrated the CPU and the switch—and in some models the PHY—into a single chip to dramatically reduce power, board space and design complexity.
Done right, TSN will lower the CapEx and OpEx for industrial technology, open the door to integrating Industry 4.0 practices and simplify the process of bringing new equipment to market. -

Designing energy efficient chips
By Rebecca O'Neill, Global Head of ESG, Marvell
Today is Energy Efficiency Day. Energy, specifically the electricity consumption required to power our chips, is something that is top of mind here at Marvell. Our goal is to reduce power consumption of products with each generation for set capabilities.
Our products play an essential role in powering data infrastructure spanning cloud and enterprise data centers, 5G carrier infrastructure, automotive vehicles, and industrial and enterprise networking. When we design our products, we focus on innovative features that deliver new capabilities while also improving performance, capacity and security to ultimately improve energy efficiency during product use.
These innovations help make the world’s data infrastructure more efficient and, by extension, reduce our collective impact on climate change. The use of our products by our customers contributes to Marvell’s Scope 3 greenhouse gas emissions, which is our biggest category of emissions.
