Service providers need tomind, deliver an architecture thatbecome more agile in order to optimize their existing network resources, shorten planningreduces TCO with highly flexible,cycles, and remove rigid network layers.high-performance innovationsthat are easy to deploy.Operators are facing the following challenges under the current environment: Static scale: The cloud and communication providers’ backbone handles the fullweight of network traffic. Therefore, it is paramount that the core network be able togrow organically along with traffic to meet escalating demands. Silicon, system, andSDN innovations for the core empower service providers to scale faster than the trafficin an elegant, elastic, redundant package—without requiring forklift upgrades. Static architecture: Virtualized services and the explosion of cloud-based applicationsare creating increasingly unpredictable traffic patterns. To handle this unpredictability,service providers need a dynamic, scale-out architecture across all layers to createprogrammable, traffic-optimized networks that support any service, anywhere. Power costs: For cloud and communication providers, the operational cost oftransmitting a packet through the core is less than the cost of the power required tomove that packet. In fact, projections suggest that over a few short years, the totalpower draw will exceed the cost of deploying the entire network infrastructure. Efficientpower utilization by the core router requires a holistic ground-up engineering approach. Facility limitations: Service providers cannot grow their facilities exponentiallyforever. They need innovations that provide a low-touch deployment model optimizedaround space availability, facility power requirements, and floor weight thresholds.Transport-oriented central office locations have the added burden of meeting EuropeanTelecommunications Standards Institute (ETSI) standard depth. Any transit routerinnovation must operate within these constraints.1
