Verizon to Deploy Juniper's Packet Transport Switches for MPLS

Verizon will deploy the Juniper Networks's PTX Series packet transport switches in major markets in the U.S. and Europe by the end of this year. Financial terms were not disclosed.

The deployment is the first major announced customer for the new packet transport platform. The companies cited an initial capacity of eight terabits per second for the high-density MPLS platform, which underpins an upgrade of the Verizon global IP backbone to 100G Ethernet, supports customer access speeds of 10G and above and enables growth for FiOS, wireless and cloud services.

"In a world where customer needs and speeds are steadily increasing, Verizon will be able to improve the scalability and efficiency of its core MPLS network by employing the industry-leading switch density of the Juniper Networks PTX Series,�? said Ihab Tarazi, vice president of global IP and transport planning and technology for Verizon. “The PTX Series provides significant packet processing power, system scale and reduced power consumption – all of which will help Verizon meet its future needs."

Verizon will initially deploy the PTX5000, which delivers eight terabits per second of capacity, with plans to eventually move toward higher terabit capacity.

"Verizon’s reputation as a pioneer in advanced communications and entertainment services was clearly demonstrated in 2010 when the company became the first service provider to commercially deploy 100G Ethernet,�? said Stefan Dyckerhoff, executive vice president and general manager for Juniper Networks Platform Systems Division. “Today, Verizon makes another landmark decision by selecting the PTX Series, the industry’s first converged packet transport switch, to advance its network core and provide future-ready scalability while dramatically simplifying its infrastructure overhead." March 2011, Juniper Networks first announced its Packet Transport Switches (PTX). The new architecture called for a single network management system for the entire transport network -- Junos -- for both the optical layer and the packet layer. The company said its 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.

  • In March 2011, Juniper said the PTX Series wiould be available for beta trials in the third quarter of 2011.
