网络、云和网络安全的服务保障

Everything about 5G networks is bigger. For 4G, a large national provider might have a network topology with ten physical data centers. Mobile core functions deployed at these locations represent the edge of the mobile network – the point at which core networks interface with radio networks via IP aggregation and backhaul networks. While expensive, for 4G, a service provider could deploy service assurance probes at each of these locations to effectively monitor all user traffic and signaling.

In this video we address the significant challenges and innovative solutions in the evolving 5G landscape. As the industry shifts towards highly software-centric networks, the skills required to manage these networks have also transformed. Test and measurement providers are stepping up to bridge this gap by developing advanced tools and methodologies. Latency issues and the demand for seamless connectivity are critical areas being addressed. Network densification, beamforming, massive MIMO (Multiple Input Multiple Output), and network slicing are essential components in managing and optimizing 5G networks. Network densification involves increasing the number of small cells in a given area to boost capacity and coverage. Beamforming and massive MIMO enhance signal quality and efficiency, while network slicing allows for the creation of virtual networks tailored to specific applications or services.

5G已经开始从最初的覆盖部署逐步进入成长期，而发现新收入机遇的紧迫性也因此不断加剧。在线游戏、增强现实/虚拟现实、视频内容和安全监视都已经成为目前正在考虑的最具前景的热点。要达到此类下一代服务所需的性能和时延指标，就需要5G完全拥抱云化架构，并且会对电信云、公有/私有云和边缘云提出前所未有的众多需求。

在今天的网络中，扼制问题的出现是一项永无止境的工作，而且会随着网络向5G、SD-WAN和NFV的演进而变本加厉。随着网络为支持这些下一代服务而逐步虚拟化，手动的故障查找方式已经跟不上形势的发展。服务商需要采用新的方法来为网络提供保障。 本白皮书将探讨保障网络的两条主要途径：传统的被动保障，需要依赖用户使用网络时被动采集的指标；以及主动保障，使用真实度极高的合成用户流量，并在不同的点将其注入网络，从而对性能和质量进行评估。

思博伦的移动测试平台（MTP）是一种空中（OTA）测试解决方案，同时也是我们的边缘服务保障解决方案中的一项关键赋能因素。该解决方案易于安装且适用于任何地点的任何用户，可以将一台真正的商用设备和最多四张SIM卡安置在小巧的装置内，并在任何需要的地方对网络性能执行监视，而不是仅仅在机柜或服务器机房内发挥作用。集中化的控制能力可以管理数以千计的设备，并具备远程重启的能力，无需再派遣外场技术人员并可能节省数千美元的费用。
