Executive SummaryThis paper is essential reading for business decision makers (up to the CxO level) in both service provider and large enterprise environments. The paper describes a unique solution set for virtualizing a service provider network through an intelligent partitioning of resources in the forwarding, control and service planes. While the networked economy heavily relies on telecom infrastructure, service providers struggle to translate ®this dependence into profitability. Juniper Networks has developed a solution to this issue in the form of a virtualized, multiservice core. The solution includes the industry's most flexible multi-chassis routing system, and it brings a new dimension of scale to the network infrastructure. Highly scalable network virtualization, as implemented by Juniper Networks, brings a... [download for more]
