Service Provider core networks are reaching a breaking point because a convergence of factors is causing huge stresses in the way networks are deployed, and destroying their basic operating economics. These include:

• New Devices — including smartphones and tablets
• New Applications — such as video streaming and social networking
• Mobility — requires anytime, anywhere access to Internet content
• Cloud Computing — with the creation of huge mega datacenters

Each of these factors is driving exponential traffic growth, and increasing the unpredictability and spiking characteristics of traffic demands. In addition, most of this new traffic is low-revenue Internet traffic. Over-provisioning of core networks has been the current method of meeting the demand, but costs are rising rapidly and revenue not matching up, so operators need a new way to build their core networks.

Current core network infrastructures are rigid: they are highly layered and built for circuits, but not built to handle the dynamics of packets. Operators are looking for ways to build a core network that can adapt to the services running over it, not the opposite as is done today. Juniper Networks' PTX Series Packet Transport solution enables operators to build a Converged Supercore that has multilayer provisioning that serves both packet and transport, while adding intelligence to each layer, removing inefficiencies, and dropping costs.

The PTX Series is a purpose-built platform for the Converged Supercore, including latest ASIC technology with low power, high speed, and low cost, optimized for MPLS switching and a multilayer Packet Transport solution. Service Providers can drive down Capital and Operating expenditures while investing in network growth with a set of approaches, including:

• Single converged super core for packet and circuit services
• Service-driven multi-layer network
• Smart multi-layer modeling, planning, provisioning, protection and restoration
• Integrated multi-layer control-plane
• Elimination of expensive high-speed short-reach interfaces
