5G transport assurance

Transport performance monitoring across all network segments and domains, from radio unit to mobile core and cloud.

Service assurance for 5G transport

5G promises new revenue enabled by an ultra-reliable, low latency (URLLC) network powered by a highly distributed services-based architecture and edge computing (MEC). The transport network underpins them all. End-to-end visibility is required to detect latency issues in real time, before they impact customer experience and business-critical services.


Latency sensitivity

Demand for real-time services like HD video streaming, remote working, and online gaming is pushing service providers to reduce latency. New value-added services (e.g., network slicing and URLLC) demand minimal, predictable latency. Isolating the latency contribution of dynamic infrastructure in multi-domain, multi-layer networks requires a new approach.

Change drivers

Optimizing the transport network in this more dynamic, complex, and business-critical context requires an inclusive, end-to-end assurance strategy. All groups—RAN, core, transport network, traffic engineering, network planning, cloud infrastructure—must do their part to shave precious millisecond delays out of each domain, while also identifying and resolving bottlenecks where they intersect.

Understanding the latency contribution of each network element is critical to optimizing the transport network.


  • 5G revenues at risk

    5G revenues depend on achieving strict performance criteria.

  • Latency as a moving target

    Ephemeral network resources introduce variations in performance and QoE.

  • Poor QoE drives churn

    Sub-optimal customer QoE leads directly to poor Net Promoter Scores (NPS).


With cloud-native test agents, detailed topology, source-agnostic data ingestion and multi-domain, multi-layer analytics, EXFO’s adaptive service assurance platform provides full visibility and diagnostics into complex transport networks, and the services and user experiences they support.

Segment by segment visibility

Synthetic test agents deployed along the service path provide segment--by--segment performance and latency metrics in dynamic networks. Real-time network topology helps to pinpoint the sources of problematic latency, enabling rapid and effective action.
