NFV(Network Functions Virtualization) | 網路功能虛擬化

  • 網路功能虛擬化是什麼?
    傳統上,管理網絡所需的功能和服務是由特殊具有嵌入式軟體的專用硬體所提供。 這些功能包括所有網絡中通用的功能,例如路由器,防火牆以及在移動蜂窩網絡中使用的特定應用程式的負載平衡器,例如PGW(分組數據網絡閘道器)或MME(移動管理引擎)。

    網絡功能虛擬化(NFV)是一種將這些功能虛擬化的新技術,將它們從依賴硬體轉變為純粹以軟件來實現。

    這些功能現在可以是容器或虛擬機中的應用程式,透過管理程序並在通用的現成x86服務器設備上運行。

  • 為何需要?
    由於網路功能虛擬化現在完全基於軟體運作,不再依賴專用的硬體,因此網絡功能的部署和管理更具可擴展性和彈性,例如,您現在可以透過軟體,立即簡單地擴展或降低負載平衡或防火牆容量,無須購買和安裝新的硬體設備。

    NFV還可以大大降低採購和營運成本,因為通用的現成伺服器硬體(例如技嘉的機架式伺服器)不僅可運行這些功能,相較於思科等供應商提供的專用硬購,投入成本也較低。像這樣集結多種功能的硬體,管理和維護成本也會大幅降低。

    此外,軟體也使NFV更加敏捷,縮短了上市時間和開發週期。只要新的網路服務和應用程式開發完成,就可以直接使用,無需額外再將新硬體安裝到資料中心。

  • 技嘉的特色
    技嘉的機架式伺服器高密度伺服器邊緣運算伺服器系列是運行虛擬化軟體應用程式的理想平台,例如網路功能虛擬化(NFV)。採用支援Intel和AMD的雙插槽處理器系統,達到高效能、低功耗的高核數運算能力,以運行大量的虛擬機或容器。

    技嘉伺服器系列具有業界領先的插槽擴充數量,每種規格或平台的插槽都可容納大量高速網路介面卡(NIC),是網路管理應用程式中不可或缺的一環。

    Ushering in a New Era of Smart Healthcare Applications with 5G-based MEC

    A new epoch of smart medicine has been made possible with the proliferation of 5G. Healthcare has advanced from the treatment of symptoms to the early detection of disease and the tracking of each individual’s condition. GIGABYTE Technology offers the highly scalable, high-density E-Series Edge Servers for edge computing; by working with Alpha Networks Inc., GIGABYTE has brought the benefits of multi-access edge computing (MEC) to wearable devices and other Internet of Things (IoT) applications that will help to realize the vision of smart medicine. The compilation of big data, coupled with the low-latency characteristics of MEC, allow for faster data integration and analysis that will help healthcare providers offer customized, predictive care for their patients.

    What is Edge Computing? Definition and Cases Explained

    With the proliferation of 5G communications technology, edge computing—the practice of performing computing tasks as physically or logically close as possible to where data is created and commands are executed—has begun to permeate the modern world of smart technology. In this article, we explore the concept of edge computing in detail, and explain how it offers many excellent advantages, especially in terms of latency reduction for applications that rely on real-time decision-making.
