Juniper Networks Delivers on Next-Generation Network Vision; Provides Service Awareness at Scale to Enhance Revenue Generation Opportunities

Strategy Offers Service Providers Greater Choice and Control in Quickly Meeting High-Performance Business Requirements

SUNNYVALE, Calif., June 11, 2007–Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, today offered service providers an innovative approach to extending service awareness from the edge into the core of next-generation networks to deliver exceptional end-user experiences, speed new differentiated services to market, control costs and capitalize on new revenue opportunities.

As service providers accelerate their transition to next-generation networks, they have compromised service awareness in the core to keep pace with the escalating capacity and throughput demands required to meet the increasing expectations of business, residential and mobile users. Juniper Networks vision to deliver agile, open and customizable next-generation network solutions offers service providers a superior approach to bringing service awareness directly into the core in a reliable and cost-effective manner.

"It's been taken as classical wisdom that you have to do all the service-aware handling of traffic at the network's edge, but that's really just an excuse for lack of policy control that can scale to high traffic levels," said Tom Nolle, president of CIMI Corporation, a Voorhees, N.J. consultancy. "If you throw traffic into a mill of statistical probabilities anywhere along the path, you cannot be sure that users will get what they pay for. The best network solution is one that knows your traffic from end-to-end, at every point where it's touched by resources. That's the solution Juniper's providing."

With a proven track record of delivering high-performance networking innovations to market, Juniper is addressing the most complex challenges facing service providers today. With an award winning and comprehensive portfolio of core, edge and access solutions, fully supported by JUNOS and fully managed through a centralized policy management portfolio, Juniper offers service providers greater choice and control in quickly meeting high-performance business requirements.

Agile, Open and Customizable NGN Solutions

Juniper shares a common vision with top service providers for next-generation networks based on an innovative architecture with defined functional separation between the packet handling, policy and control, and service layers. Juniper's unique approach is to deliver NGN solutions which are agile, supporting a multitude of services; open to link applications to network resources; and customizable in their ability to create differentiated services.

Session and Resource Control, Setting the Standard in Service Management

Juniper recently announced a portfolio of Session and Resource Control solutions that provide real-time service management through open interfaces and deep policy control capabilities that enable service providers to provide a satisfying user experience for multiplay, voice, video and IP Multimedia Subsystem (IMS) mobile services in next-generation networks.
