Juniper pushes ahead with 400G based on its own silicon

Juniper Networks is bringing 400GbE capabilities across its wide-area network, data center and enterprise portfolio starting in the second half of 2018, including 400GbE in backbone, peering, data center interconnect, scale-out metro core, telco-cloud services and hyperscale data center IP fabrics.

The announcement includes product refreshes for Juniper’s PTX, QFX and MX series platforms based on the company's recently announced 400GbE-capable Juniper Penta Silicon, and new generations of ExpressPlus and Q5 silicon. Juniper's in-house silicon brings native 400GbE and Flex Ethernet support with tighter MACsec integration. Juniper said its next-generation silicon also brings forward all existing functionality in previous generations while adding deep telemetry, SPRINGv6 and VXLAN EVPN support.

“The impending wave of network traffic is coming from all angles and affecting all industries. Success will be about not only equipping the network with the right technology to handle the traffic in a secure way but also fine-tuning the economics so it makes good business sense. We’re putting a stake in the ground today in leading our customers’ transition to 400GbE network capacity with the industry’s most comprehensive set of use cases, including backbone, peering, data center IP fabric and metro core, to enable our customers to economically usher in the next era of connectivity,” stated Bikash Koley, Chief Technology Officer, Juniper Networks.

Highlights of the announcement:

400GbE for IP Transport

Juniper is unveiling a new 3-RU PTX10003 Packet Transport Router for next-generation backbone, peering and data center interconnect applications ready to deploy high-density 100GbE and 400GbE. The new PTX10003 is the industry’s first packet transport router to accommodate universal multi-rate QSFP-DD interface for seamless 100GbE to 400GbE upgrades. It features native MACsec support for 160x100GbE and FlexE support for 32x400GbE interfaces. The Juniper PTX10003 is powered by the next generation of its ExpressPlus silicon. Commercial availability is expected during the second half of 2018.

400GbE for the Data Center

  • Juniper is introducing a QFX10003 data center switch boasting 32x400GbE in a compact 3-RU form factor. The system can scale up to 160x100GbE giving customers investment protection as they transition to 400GbE. The QFX10003, which will be powered by the next generation Q5 silicon, features a deep buffer enabled by Hybrid Memory Cube memory, allowing it to absorb network traffic spikes and reduce application latency across MACsec encrypted 25GbE, 50GbE, and 100GbE environments. QFX10003 is expected to be available during the second half of 2018.


  • Juniper is also introducing new QFX5220 switches powered by the latest generation of merchant silicon and offering 32x400GbE in a compact 1-RU form factor. These switches also offer flexible 50GbE, 100GbE and 400GbE interfaces for server and inter-fabric connectivity, providing deployment versatility and network investment for the 400GbE cloud transition. The QFX5220 is expected to be available in the first half of 2019.

400GbE for WAN services

  • Juniper's recently announced MX Series 5G Universal Routing Platform, powered by its own new Penta Silicon, offers 400GbE interfaces and industry-first support of native MACsec and IPsec encryption that can originate and terminate thousands of IPsec sessions without sacrificing performance. Juniper Penta Silicon-powered 400GbE MPC10E line cards for the MX960, MX480 and MX240 are expected to be available in the first half of 2019. 


Juniper refreshes MX edge routers powered by its Penta silicon

Juniper Networks introduced its new MX Series 5G Universal Routing Platform powered by a new generation of its custom ASICs promising extensive programmability and performance improvements for supporting resource-intensive applications like 5G and secure SD-WAN-based managed services.

The new "Penta" silicon, which leverages 16nm geometry, functions as the packet forwarding engine for the MX series. It delivers a 50 percent power efficiency gain (0.5 watts per gigabit) over the existing Junos Trio chipset, which leads to a 3x bandwidth increase for the MX960, MX480 and MX240. Juniper designed the Penta silicon with native support of both MACsec and an IPsec crypto engine – an industry-first – that can originate and terminate thousands of IPSec sessions without sacrificing performance. Additionally, Juniper Penta supports flexible native Ethernet support (FlexE).

Juniper Penta silicon features:

  • 16nm with Integrated 3D HBM Memory reducing packaging by 83% over the 4th Generation Trio silicon 
  • 500G Full Duplex / 1T Half Duplex 
  • 50Gbps SERDES 
  • Fully Programmable Packet Pipeline 
  • Fully Fungible Integrated Databases for FIB, ACLs, Tunnels, Telemetry, and more… 
  • Built-in FlexEthernet Support 
  • Built-in MACSec & IPSec Tunnel Encryption Engine (Industry First)
A second major innovation with the platform is open hardware-accelerated 5G Control and User Plane Separation (CUPS), which enables operators to separate the evolved packet core user plane (GTP-U) and control plane (GTP-C) with a standardized Sx interface. This allows service providers to scale the control plane and the user plane independently as needed for added flexibility and investment protection.

Juniper said its MX Series 5G platform is the first networking platform to support a standards-based hardware accelerated 5G user-plane in both existing and future MX routers to enable converged services (wireless and wireline) on the same platform while also allowing integration with third-party 5G control planes. Juniper expects this will lower total cost of ownership by as much as three to four times over software-based user plane implementations for MXs deployed in the field.

In addition, the rollout expands Juniper Universal Chassis system. The previously announced PTX and QFX Universal Chassis gains two new MX variants: MX10008 and MX10016. The 13-RU MX10008 and 21-RU MX10016 Universal Chassis bring industry-leading and space-saving scale for edge routers at 19.2Tbps and 38.4Tbps, respectively.

The MX10008 and MX100016 will be available during the second half of 2018. Juniper Penta Silicon-powered line cards for the MX960, MX480 and MX240 will be available in Q1 2019. New CUPS support will be available in the first half of 2019.
