  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.

  妥協のない5GオープンRAN： コンピュート・アーキテクチャ

  By Peter Carson, Senior Director Solutions Marketing, Marvell

  はじめに

  5G networks are evolving to a cloud-native architecture with Open RAN at the center. This explainer series is aimed at de-mystifying the challenges and complexity in scaling these emerging open and virtualized radio access networks. Let’s start with the compute architecture.

  The Problem 

  Open RAN systems based on legacy compute architectures utilize an excessively high number of CPU cores and energy to support 5G Layer 1 (L1) and other data-centric processing, like security, networking and storage virtualization. As illustrated in the diagram below, this leaves very few host compute resources available for the tasks the server was originally designed to support. These systems typically offload a small subset of 5G L1 functions, such as forward error correction (FEC), from the host to an external FPGA-based accelerator but execute the processing offline. This kind of look-aside (offline) processing of time-critical L1 functions outside the data path adds latency that degrades system performance.

  次世代イーサネットで5Gネットワークのパフォーマンスを引き出す

  By Alik Fishman, Director of Product Management, Marvell

  Blink your eyes. That’s how fast data will travel from your future 5G-enabled device, over the network to a server and back. Like Formula 1 racing cars needing special tracks for optimal performance, 5G requires agile networking transport infrastructure to unleash its full potential. The 5G radio access network (RAN) requires not only base stations with higher throughputs and soaring speeds but also an advanced transport network, capable of securely delivering fast response times to mobile end points, whatever those might be: phones, cars or IoT devices. Radio site densification and Massive Machine-type Communication (mMTC) technology are rapidly scaling the mobile network to support billions of end devices¹, amplifying the key role of network transport to enable instant and reliable connectivity.
  
  With Ethernet being adopted as the most efficient transport technology, carrier routers and switches are tasked to support a variety of use cases over shared infrastructure, driving the growth in Ethernet gear installations. In traditional cellular networks, baseband and radio resources were co-located and dedicated at each cell site. This created significant challenges to support growth and shifts in traffic patterns with available capacity. With the emergence of more flexible centralized architectures such as C-RAN, baseband processing resources are pooled in base station hubs called central units (CUs) and distributed units (DUs) and dynamically shared with remote radio units (RUs). This creates even larger concentrations of traffic to be moved to and from these hubs over the network transport.

  マーベル、5Gの真の可能性を引き出すO-RANを実現

  マーベル、PR チーム

  At the most recent FierceWireless 5G Blitz Week, some of the world’s leading 5G innovators met via webinar to discuss the potential of O-RAN and challenges of the ongoing 5G rollout. In a keynote, EVP and General Manager of Marvell’s Processors Business Group Raj Singh explored the accelerating shift to O-RAN, which is an emerging open-source architecture for Radio Access Networks that enables customers to create better 5G applications by mixing and matching RAN technology from different vendors.

  O-RAN architectures are compelling because they increase competition among vendors, reduce costs, and offer customers greater flexibility to combine RAN elements according to their application’s specific use cases. However, in addition to their obvious benefits, O-RAN solutions also raise operator concerns including potential challenges with integration, legacy support, interoperability and security – issues that Marvell and other companies in the Open RAN Policy Coalition are addressing through shared standards, proven solutions and innovative approaches.
