A software-defined wide area network(SD-WAN)is a wide area network that uses software defined network technology,such as communicating over the Internet using overlay(69)which are encrypted when destined for internal organization locations.SD-WAN simplifies the management and operation of a VAN by decoupling the networking hardware from its(10)mechanism.This concept is similar to how software-defined networking.Implements(71)technology to improve data center management and operation.A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available(72)access,enabling businesses to partially or wholly replace more expensive private WAN connection technologies.SD-WAN technology supports(73)of Service(QoE)by having application-level awareness,giving bandwidth priority to the most critical applications.此题为第73问
Quantity
Quality
Query
Queue
翻译如下
软件定义广域网(SD-WAN)是一种使用软件定义网络技术的广域网,例如通过互联网使用叠加(69)进行通信,这些叠加在传输到组织内部位置时是加密的。SD-WAN通过将网络硬件与其(70)机制解耦,简化了虚拟专用网络(VAN,此处原文可能为WAN的笔误,但根据上下文理解为广义的网络管理)的管理和操作。这一概念类似于软件定义网络如何通过实施(71)技术来改进数据中心的管理和操作。SD-WAN的一个关键应用是允许公司使用成本更低且商业上可用的(72)接入来构建性能更高的广域网,使企业能够部分或完全替代更昂贵的私有广域网连接技术。SD-WAN技术通过具有应用级感知能力,为最关键的应用程序提供带宽优先级,从而支持服务(73)(QoE)。
A. Quantity(数量)
B. Quality(质量)
C. Query(查询)
D. Queue(队列)
QoE(Quality of Experience)指的是用户体验的质量,SD-WAN通过为最关键的应用程序提供带宽优先级来支持这一目标。
