Integrating optical and IP technology future-proofs Swedish network
Swedish operator SUNET builds a converged optical-IP network that delivers new levels of automation, uptime, and scale while slashing operating costs.
SUNET connects about a half a million students, researchers, and administrators across 30 schools and 100 research institutions. In addition to high-speed network connectivity, SUNET offers cloud storage, digital collaboration tools, and Web conferencing services.
With vendor contracts coming due and existing equipment needing an overhaul, SUNET sought a new approach to building and operating its high-performance academic network. It wanted a more automated network that was highly resilient to downtime and could scale into the future.
SUNET built an integrated IP-optical network using Juniper MX Series routers, which scale beyond 80 Tbps and support ultra-high-density 10GbE, 40GbE, and 100GbE interfaces. The SUNET core uses Juniper Modular Port Concentrators with dense wavelength-division multiplexing (DWDM) coherent optical interfaces, the first deployment of its type in the world.
The converged IP-optical SUNET is 10 times faster, though operational costs have dropped 20 percent. Simplifying the network with convergence has improved network availability because there are fewer components to fail. The router inherently understands fiber connections, so it can reroute traffic before a fiber has even broken.
