Juniper's Converged Supercore Packs MPLS Switching + Optical

Juniper Networks introduced two Converged Supercore platforms for packet optical transport.

Juniper's new architecture calls for a single network management system for the entire transport network -- Junos -- for both the optical layer and the packet layer.

The aim is to combine the efficiency of MPLS, the simplicity of switching and integrated optics to deliver network scale with fewer network elements.

By collapsing the packet and transport network layers, the Converged Supercore would help carriers save money in network management and operations, whike taking uncertainty and cost out of core network provisioning. Juniper is forecasting network CAPEX cost savings of 40 to 65 percent compared to traditional architectures and a 35 percent savings versus a pure IP routing solution.

The new Converged Supercore switches are based on a new Junos Express chipset that is optimized for high capacity transport and features the on-chip traffic engineering, full delay bandwidth buffers, algorithms optimized for packet transport and embedded error detection required to support differentiated traffic types and patterns without disruption. Junos Express is built in 40 nanometer technology with 3.55 billion transistors. It represent an R&D investment of $40 million. Junos Express is the second chipset in the Junos One family of processors, which the company developed in-house.

Some highlights of the products:

  • PTX5000 scales to 384 10 GE interfaces, 64 100 GE interfaces and 192 40GE interfaces in a single chassis. The architecture delivers 480 Gbps per slot and is designed to scale up to 2 Tbps per slot. Packet processing is rated at f 720 Mpps per slot. The PTX5000 features fully redundant, High Availability hardware (cooling, power supply, routing engines, control board and SIB). In addition, the PTX supports 50 ms redundancy switchover under load.

  • The PTX9000 switch, is double the capacity of PTX5000, and is the foundation of the converged supercore delivering statistical multiplexing, high capacity MPLS switching and Multilayer packet-transport manageability.

  • Juniper will be offering a suite of 10/40/100GE short-reach and ultra long-haul DWDM interfaces.

  • The PTX Series will be available for beta trials in the third quarter of 2011.
