The deployment will span CoreExpress' Internet Data Exchange System (iDES(SM)), which includes a 22,000-mile redundant, OC-192 fiber optic network. The Juniper Networks routers will act as gateways for customer traffic into the CoreExpress iDES platform from an ISP's network and enable CoreExpress to offer site-to-site performance guarantees for individual customers. These guarantees ensure high availability and minimal loss and latency between a customer and its partners, even if they use different ISPs.

It will also enable CoreExpress to provide Service Level Agreement compensation directly proportional to the traffic sent to an affected site.
