    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.

    Wind River 和 Marvell 携手为 CSP 扩展虚拟 RAN 解决方案

    By Kim Markle, Director Influencer Relations, Marvell

    Wind River and Marvell have collaborated to create an open, virtualized Radio Access Network (vRAN) solution for communication service providers (CSPs) that offers cloud scalability with the features, performance, and energy efficiency of established 5G networks. The collaboration integrates two complementary, industry-leading technologies—the Marvell® OCTEON® 10 Fusion 5G baseband processor and the Wind River Studio cloud software—to provide the carrier ecosystem a deployment-ready vRAN platform built on technologies that are widely proven in 5G networks and data centers.  

    CSPs aim to leverage established IT infrastructure for enhanced service agility and streamlined DevOps in the cloud-native RAN. Marvell's OCTEON 10 Fusion processor supports these goals with programmability based on open-source, industry-standard interfaces and integration with leading cloud software platforms such as Wind River Studio.

    To ensure open-source distribution of Wind River Studio software, OCTEON 10 Fusion software drivers are being used by StarlingX, an open development and integration project. Marvell’s drivers enable Wind River Studio software to communicate with and control the OCTEON 10 Fusion processor. This facilitates developer access to an optimized vRAN system that offers new options for CSPs and helps to expand the carrier ecosystem of RAN and data center hardware and software suppliers, as well as system integrators.

    5G 接入网的光学技术

    By Matt Bolig, Director, Product Marketing, Networking Interconnect, Marvell

    There’s been a lot written about 5G wireless networks in recent years.  It’s easy to see why; 5G technology supports game-changing applications like autonomous driving and smart city infrastructure.  Infrastructure investment in bringing this new reality to fruition will take many years and 100’s of billions of dollars globally, as figure 1 below illustrates.

    When considering where capital is invested in 5G, one underappreciated aspect is just how much wired infrastructure is required to move massive amounts of data through these wireless networks.

    Last week, Moor Insights and Futurum Research kicked off The Six Five Summit, a virtual, on demand event focused on the latest developments and trends in digital transformation. Marvell was thrilled to join alongside the world’s leading technology companies to share insights on strategy, innovation and where the industry is heading.

    Marvell’s Raghib Hussain, President, Products and Technologies participated in the event’s Cloud and Infrastructure Day to discuss the evolution of the cloud data center including the shift from application-specific to data-centric compute. In his presentation, “Accelerating the Cloud Data Center Evolution,” Raghib focuses on how scalability, performance and efficiency are driving technology infrastructure requirements and why optimized and customized silicon solutions are the future of the cloud.

    实现网络处理边缘化: 安全

    By Alik Fishman, Director of Product Management, Marvell

    我们在先前的“实现网络处理边缘化”系列中探讨了将智能、性能和遥测向网络边缘推进的相关趋势。 本部分将介绍网络安全的角色转变,以及将安全功能整合至网络接入的方法。这些方法可以在整个基础设施内有效推动策略实施、保护和修复的简化。

    随着移动设备和物联网设备等新数据源在工作场所的快速普及,遭黑客攻击和遭泄露的数据数量也迅猛增长。不少企业深受其害,网络安全威胁成为困扰他们的日常难题。 安全漏洞也呈现新的发展趋势,不但数量持续上升,严重性和持续时间也在增长,从入侵到控制的平均生命周期长达近一年,1给运营带来巨大的成本压力。 而数字化转型和新兴技术格局(远程访问、云原生模型、物联网设备激增等)的出现,使网络架构和运营受到巨大影响,也催生出新的安全风险。 大刀阔斧地变革企业基础设施,提升网络智能、性能、可视性和安全性2,已经刻不容缓。

    遥测: 您的边缘可见性如何?

    作者:软件工程高级总监 Suresh Ravindran

    我们在先前的“利用网络边缘计算”系列中探讨了将智能和性能向网络边缘推进的相关趋势。 这篇博客将谈谈对于网络可见性的需求。

    随着自动化趋势不断演进,互联设备数量呈现 爆炸式增长。 据 IDC 估计,到 2025 年将有 416 亿台设备 连接至物联网 (loT),生成多达 79.4 泽字节的海量数据1。 视频流和 传感器流量在这类流量中将占到相当大的比例, 需针对混合云模式中的个性化用户服务、 库存管理、入侵防护和负载平衡等应用进行 智能处理。 联网设备将需要具备智能管理 资源处理的能力,才能高效地处理 海量数据流。

    随着我们迈向“永远在线,始终连接”(Always On,Always Connected)模式的更高阶段,手机已然成为我们生活中的核心部分。 手机为我们提供对数据和通信媒介的即时访问,这种方式的访问影响着我们的决定,并最终影响我们的行为。

    据思科预计,到 2022 年,全球移动网络将支持超过 120 亿台移动设备和物联网 (loT) 连接。1 这些移动设备将支持多种功能。 手机已经取代了各种小工具,为我们提供多种服务。 如果手机可以提供 Apple Pay、Google Pay 或电子支付功能,即没有必要随身携带钱包。 如果手机可以解锁并启动汽车或打开车库门,即没有必要随身携带车钥匙。 现在,应用程序还包括实时流媒体服务,这些服务可支持 VR/AR 体验和实时共享。 未来的移动服务和应用程序似乎充满各种可能,它们依然需要下一代数据基础架构来支持和促进其发展。
