Zayo Group Lights Up Performance and Lowers Cost with 100GbE Core Network from Juniper

Zayo needed a cost-effective, high-performance, BGP-free MPLS network with the density to meet growing bandwidth needs of Ethernet customers across the U.S. and Europe.

Based in Boulder, Colo. with European headquarters in London and Paris, Zayo runs a network that stretches 82,000 miles and offers a wide range of services, including dark fiber, wavelengths, Ethernet, IP services, SONET, interconnection, and collocation to telco, education, finance, healthcare, oil and gas, and utility customers.

"We needed to re-architect our network to stay ahead of the bandwidth growth curve. It made financial sense to set up a brand new core limited to Layer 2 protocol enabling a faster, convergent core network."
Chris Morley President of Cloud and Connectivity, Zayo Group

Business Challenge

As customers demand innovative physical infrastructure and bandwidth services, providers have to keep up with the latest technology to offer the best performance and services. Zayo needed a next-generation 100GbE core network with a scalable service-oriented Ethernet edge to meet its customers' growing bandwidth needs.

Technology Solution

Zayo sought a routing solution that would be faster and better than the competition, delivering the performance, form factor, and optical integration it needed to grow its Layer 2 revenue. Zayo Group chose Juniper's SDN-ready PTX Series Packet Transport Routers for its core network in the U.S. and Europe, and the SDN-ready MX2010 router for its metro areas.

Business Results

Zayo has saved $1.8 million annually on power and cooling costs over other vendor solutions. The BGP-free MPLS core is capable of 8 Tbps and has the ability to grow to eight 100GbE ports per slot. Zayo can quickly deploy 100 Gbps services, and has significantly improved the customer experience through faster service agility and service availability.


"Our total cost of ownership is lower, making Juniper a great investment for Zayo."
