Juniper Debuts 3 Tbps PTX1000 Supercore Router

Juniper Networks introduced its compact, 3 Tbps, PTX1000 supercore router.

Like the larger PTX3000 and PTX5000 core routers, the new two-rack unit (RU) router uses Juniper's 28nm ExpressPlus chipset for IP/MPLS performance applications. The 28-nanometer chip can drive 5x100G interfaces and leverages 3D memory architecture, which reduces power consumption and space requirements. In addition, the PTX1000 features flexible port interface options to maximize investment protection and ensure smooth upgrade cycles.

Commercial deliveries are expected in Q3.

“For telecom service and cloud content providers, the network is the lifeblood of their business. Juniper is always looking for new ways to ensure the network is a true competitive advantage for them. In developing the PTX1000, we recognized that these customers can increase performance while reducing operational complexity by distributing the load of serving up content across multiple peering points to deliver the high quality user experience that consumers expect,” stated Paul Obsitnik, vice president of service provider marketing, Juniper Networks.

In March 2015,  Juniper Networks rolled out a series of enhancements to its Converged Supercore PTX Series router based on new custom silicon and expanded software-defined networking (SDN) capabilities. The PTX routers combine full IP and MPLS functionality, transport integration and SDN programmability.

Juniper said its new ExpressPlus custom ASIC is capable of performing more than 1.5 billion filtered operations per second and scaling up to 500 Gbps (1 Tbps half-duplex).It delivers four times the performance and three times the efficiency gains over Juniper’s previous-generation Express chipset. 

The new silicon enables the PTX5000 routers to deliver 3 Tbps per slot (30x100GE interfaces) for a total capacity of 24 Tbps (48 Tbps half-duplex).  Energy efficiency is estimated at 1/2 watt per gigabit. In terms of size, the PTX3000 is designed for space-constrained environments and can scale up to 8 Tbps or (16 Tbps half-duplex) in a form factor 91 percent smaller than its nearest competitor. Juniper will also introducing new line cards for the PTX Series core routers.

In addition, Juniper has extended the capabilities of its NorthStar Controller to provide visibility and control into additional layers of the network and fully support and handle dynamic traffic, such as that driven by mobile and cloud applications. Juniper said these capabilities enable the NorthStar Controller to increase utilization by dynamically adjusting to changing network conditions in real-time.
