Case Study: SUNET achieves 10× faster speeds, ~20% lower costs and greater resilience with Juniper Networks' converged 100GbE optical‑IP solution

Converged 100GbE Optical IP Integration Scales Sweden’s National Academic Network

SUNET, Sweden’s national academic network serving more than 30 universities, colleges and 100 research institutions, faced end‑of‑life optical equipment, a dark‑fiber contract renewal, and rising traffic demands. The organization needed a more scalable, resilient and cost‑effective network that supported open standards and avoided vendor lock‑in while containing operational costs as traffic grew.

SUNET deployed a converged IP‑and‑optical solution from Juniper (MX2020/MX2010/MX960/MX480 with integrated 100GbE coherent optics) over ~8,000 km of dark fiber with Adva DWDM gear and IPNett integration. The integrated approach eliminated separate transponders, enabled a grid‑less DWDM domain and automated provisioning, delivering a network more than ten times faster, about 20% lower operational costs, greater availability and a scalable path to multiple 100GbE and future terabit links.
