5Gネットワークの安全性は？
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.

ウインドリバーとマーベル、CSP向け仮想化RANソリューションの拡充で協業
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.

マーベルとVMwareがRANの最適化に向けて協力
By Peter Carson, Senior Director Solutions Marketing, Marvell and Tosin Olopade, Technical Product Line Manager, VMware and Padma Sudarsan, Director of Engineering, RAN Architecture, VMware
VMware, a pioneer in assisting communication service providers (CSPs) in transforming their networks, is partnering up with Marvell, a leading provider of data infrastructure semiconductor solutions to improve RAN performance and ROI. This collaboration provides solutions that enable CSPs to meet the demands of 5G’s increased capacity and use cases, optimizing the revenue and efficiency of each RAN site.
RAN sites worldwide are targeted for new technology deployment, where traditional, custom-made equipment is being replaced with servers adapted from data centers. This transformation to virtualized RAN and Open RAN, which replaces hardware with software, is driving the modernization of RAN sites worldwide. This allows CSPs to select servers and software based on their strategic goals, enabling them to offer unique services compared to their competitors.
However, 5G RAN workloads, particularly Layer 1 (L1), are far more complex and latency-sensitive than the applications that general purpose CPUs have been designed to address. The load on even the most robust CPUs in the case of 5G RAN virtualization can be demanding. The rapid increase in 5G network speeds, reaching multi-gigabit-per-second, and the management of software-centric RAN Distributed Units (DUs) has resulted in rising energy consumption and cooling demands. This leads to increased costs, such as higher electricity bills, and may compromise CSPs’ plans to monetize their RAN investments.

オープンでクラウドネイティブな5G RANへの妥協なきアプローチ
By Peter Carson, Senior Director Solutions Marketing, Marvell
The rise of fully open and optimized vRAN platforms based on globally-proven 5G layer one hardware accelerators, led by Marvell, has given Open RAN operators the industry’s first no-compromise vRAN solution. Unlike the so-called “look-aside” general-purpose alternative, the Marvell architecture is host server CPU agnostic and uniquely enables (1) RAN software programmability, based on open source, industry standard interfaces and (2) inline hardware acceleration that delivers feature, performance and power parity as compared to existing 5G networks -- absolutely critical requirements of mobile operators. Listen to what leading operators are saying about inline vRAN accelerators.

ソフトウェアで定義された自動車のためのソフトウェアで定義されたネットワーキング
マーベル、オートモーティブビジネスユニット、マーケティング担当バイスプレジデント、アミール・バー・ニヴ、ソナタス、および最高マーケティング責任者、ジョン・ハインライン、マーベル、オートモーティブビジネスユニット、SW担当副社長、サイモン・エーデルハウス著
ソフトウェアデファインド車両（SDV）は、自動車業界における最新かつ最も興味深いメガトレンドのひとつである。 以前のブログ で述べたように、この新しいアーキテクチャーとビジネス・モデルが成功する理由は、すべての利害関係者にメリットをもたらすからである：
- OEM（自動車メーカー）は、アフターマーケットサービスや新たなアプリケーションから新たな収入源を得るだろう。
- 車の所有者は、車の機能や特徴を簡単にアップグレードできる。
- モバイル通信事業者は、新しいアプリケーションによる車両データ消費の増加から利益を得るだろう。
ソフトウェアデファインド車両とは何か？ 正式な定義はないが、この用語は、柔軟性と拡張性を可能にするため、車両設計におけるソフトウェアの使用方法の変化を反映している。 ソフトウェアデファインド車両をよりよく理解するためには、まず現在のアプローチを検証する必要がある。
今日の自動車機能を管理する組込み制御ユニット（ECU）にはソフトウェアが含まれているが、各ECUのソフトウェアは他のモジュールと互換性がなく、孤立していることが多い。 更新が必要な場合、車両の所有者はディーラーのサービスセンターに出向かなければならず、所有者は不便を強いられ、メーカーにとってはコストがかかる。
