Market Trends
DIA as the foundation of SD-WAN and SASE
Enterprises in 2025 are shifting from MPLS to internet-based WANs. DIA provides the predictable underlay required for SD-WAN and SASE, ensuring consistent quality for voice, video, and SaaS workloads.
AI and GenAI workloads drive symmetrical bandwidth
The rise of enterprise AI applications is increasing demand for low-jitter, symmetrical bandwidth. Branches and plants running inference workloads are adopting DIA to guarantee reliability and low latency.
On-demand bandwidth becomes standard
With seasonal and workload fluctuations, enterprises now expect elastic DIA that can scale up and down instantly. Providers are introducing software-driven provisioning and APIs to automate bandwidth adjustments.
Multi-gig DIA tiers at the enterprise edge
Large enterprises are adopting multi-gigabit DIA as a standard, not premium, service. Buyers compare costs across multiple ISPs, pushing providers to enhance transparency in pricing and SLAs.
Security integration at the DIA port
Providers increasingly embed DDoS mitigation, telemetry, and monitoring directly into DIA ports. Enterprises are aligning network and security operations as internet underlays become core to digital resilience.
Cloud-proximate access for SaaS
Cloud adjacency is shaping DIA purchasing decisions. Telstra and others now offer direct peering services to reduce latency, improving application performance for collaboration, VDI, and transaction-heavy workloads.
Regulatory mandates accelerate migration
The UK’s 2025 analogue switch-off and other national fibre programs are forcing enterprises to replace legacy copper with DIA. This is speeding up adoption timelines and driving DIA penetration across sectors.
