VisionWorks

Preventing outages before they escalate is critical for modern network reliability. A North American Tier 1 CSP transformed its network operations by implementing Spirent VisionWorks, achieving real-time visibility and actionable insights to proactively identify and resolve potential issues. By detecting problems up to 8 hours before outages occurred, the CSP avoided costly service disruptions and ensured superior subscriber satisfaction. __The Challenge__ Operating in a siloed network environment, the CSP struggled with fragmented data and reactive troubleshooting methods. With limited visibility across network segments, interconnected issues often went unnoticed until they escalated into widespread outages. Resource constraints further stretched teams tasked with managing both 4G and 5G networks. The CSP needed a solution to provide holistic visibility and enable proactive issue resolution.

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.

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。

我们已经进入了5G的时代，以及5G带来的闪电般的速度、惊人的覆盖密度、巨大的区域流量容量，以及超低的时延。5G已经不仅仅是4G的速度升级，而是一次激进的飞跃，不仅急剧提升了各类移动宽带服务，还通过实现全球数十亿设备的互连而实现了真正意义上的物联网（IoT）。 在迈向5G的过程中，多数运营商采用的都是一种演进式的方法，即首先使用4G演进分组核心网（EPC）控制/用户层分离（CUPS），之后才迁移到5G非独立组网（NSA），并最终部署完整的原生5G或采用Open RAN。要想保障从4G到原生5G的成功旅程，我们需要的是适用于该旅程中每一个阶段和服务生命周期中每一个阶段的测试和保障能力。 思博伦的解决方案可以在整个服务生命周期中为您的5G演进之旅提供测试和保障，即从实验室以生产网络的全过程。欢迎下载我们的描述各项5G网络功能的海报，快速了解5G网络的整体结构和各项相关的服务。
