In fact, our enterprise clients can deploy ports on a per-location basis in sizes that vary from 10 Mbps to 300 Mbps to 1G to 10G.Global Reach- Within local markets, network-to-network interfaces (NNIs) connect the GTT network with hundreds of last-mile network providers around the world. At the metro edge, GTT again relies on Juniper equipment. We have deployed its MX and EX routers to connect local markets into the entire GTT core network. With its ability to tie together all the architectural components into one large, robust network, the Juniper equipment helps to make our network one of the most interconnected global infrastructures in the industry. As a result, GTT gives its enterprise clients the truly global reach necessary to connect to any location in the world and with any application in the cloud.Resiliency - The features and functionality of Juniper's routers fit perfectly within the GTT network's fully-meshed IP/MPLS topology. With every Juniper router able to talk to every other Juniper router within the IP/MPLS core, every single GTT location connects to every other GTT location, and every network path has a backup path. The Juniper equipment helps to make GTT's network an ultra-efficient infrastructure, one that offers our enterprise clients a very high level of resiliency at the core level.Enhancing that resiliency with the ability to monitor enterprise clients' end-to-end services is another reason we choose Juniper equipment. First, the Juniper platform's operations, administration and maintenance (OAM) function enables our network expertsto look at Layer-2 servicesend to end throughout the network environment. Because an enterprise client's point-to-point service may span four routers and two or three PoPs, the granular visibility we obtain with the Juniper platform allows us to isolate and resolve faults quickly.In addition, thanks to a direct application programming interface (API) in the Juniper routers, we can extract every type of information and component on each router. As a result, the Juniper platform enables GTT to expand and accelerate our fault-isolation capabilities, which improves the mean time to repair (MTR) and thereby enhances the enterprise application's reliability.Juniper-based GTT Network Gives Enterprise Clients a Competitive EdgeIn today's competitive, global marketplace, multinational enterprises want cloud-networking solutions that are not only cost-effective but also highly reliable. GTT's all-Juniper network spans more than 100 nations and 300 markets with 99.999 percent reliability. That level of network uptime enables GTT to satisfy the most stringent service-level agreement (SLA) for enterprise clients.Further, theall-Juniper core delivers operational efficiencies which accelerate repair times, strengthen application performance and provide a shorter convergence time, which is a measurement of how long it takes the entire network to converge on a new path in the event of a problem. The Juniper core ensures dynamic re-routing of traffic around a problem and onto a new path, with no worries about multi-vendor interoperability or technician-training issues.An Outstanding Cloud Network Enables Enterprise Clients to Stand Out With the high-performance, scalable and resilient Juniper platform, we have built the GTT networkto give multinational enterprise clients what they need to outpace their competitors, including access to a transit service, a private MPLS service and a private Layer-2 VLAN service on a single circuit over any loop medium anywhere in the world. Because Enterprise IT executives no longer have to lease separate services, they can reduce their costs and their operational expenses.In short, with the Juniper platform as its foundation, the GTT network is an asset on which both GTT and its enterprise clientscan build long-term cloud-computing success.
