Juniper Networks’ new Metro Fabric modernises metro service delivery

5G-ready architecture simplifies metro service delivery with an adaptive, agile and secure network designed to optimise costs and speed service creation

London, UK – 13th March 2018 – Juniper Networks (NYSE: JNPR), an industry leader in automated, scalable and secure networks, today announced its new vision for simplifying service delivery in complex metro networks. Building on the company’s recent Affirmed Networks/Netronome, Juniper® Contrail® Provider Cloud and Juniper Networks® Programmable Photonic Layer announcements that enable service providers to easily build and manage distributed clouds for new 5G and IoT services, Juniper’s new Metro Fabric is designed to provide an adaptive, agile and secure network infrastructure for simplified service creation and delivery in the metro.

The variety of services and the number of connected devices supported across metro networks – the layer of a service provider’s infrastructure most commonly associated with connecting subscribers to the internet – has recently expanded exponentially. Ethernet business services, popular applications like Netflix and Skype, IaaS offerings like Amazon Web Services and a throng of IoT devices have proliferated and this will only continue with emerging 5G rollouts. The result is a complex web of legacy products, manual processes and divergent architectures and protocols that have hindered true innovation and rendered it difficult for service providers to keep up with bandwidth demands and cost constraints.

Juniper’s Metro Fabric, comprising the industry’s only disaggregated programmable photonic layer as well as refreshed Juniper Networks ACX Series Universal Metro Routers and PTX Series Packet Transport Routers, will infuse automation, versatility, security and IP and open packet-optical networking into the metro for new levels of operational simplicity. Service providers building metro services for mobile, business, cable, fibre residential and direct public cloud use cases, can now leverage a modern service creation platform to quickly and efficiently deliver new revenue-generating services. Today, Juniper is introducing the initial building blocks of the refreshed metro: two new ACX Series Routers, as well as a new PTX Series Packet Transport Router.

“In our commitment to engineer simplicity into all layers of the network, we are excited to deliver these new capabilities focused on transforming how service providers modernise service delivery in the metro.” says Sally Bament, vice president, service provider marketing, Juniper Networks.

By combining adaptive and predictive software with new and existing network infrastructure offerings, we are evolving our solutions to enable service providers to deploy a metro network capable of faster service creation and time-to-revenue for a new generation of services and applications, including emerging 5G and IoT services.

The company also intends to continue executing against its plan to deliver a Self-Driving NetworkTM across its networking portfolio, including the new Metro Fabric.

News highlights:

  • Metro Fabric introduces the foundational elements of the refreshed metro, and is designed to give service providers hardware and software platforms to easily create and manage new services, reduce operating costs and optimise capital investment. Today, Juniper is announcing:
    • ACX5448 Universal Metro Router: Built to smooth the transition from 10GbE to 100GbE as providers prepare for the emerging 5G rollout, the ACX5448 features 48 10GbE aggregation ports and four high-capacity 100GbE uplink ports, supporting full Metro Ethernet and IP/MPLS VPN services in a space- and cost-optimised platform. The ACX5448, working in conjunction with the existing ACX500, ACX1000 and ACX2000 Universal Metro Routers, brings operators robust service-level agreement control capabilities combined with automation and zero-touch provisioning to enable a seamless migration and simplified operations
    • ACX6360 Universal Metro Router: Built to bridge between a secure packet-optical transport layer and IP/MPLS networking, the ACX6360 gives service providers the ability to collapse multiple layers into a single platform to simplify their metro networks. The ACX6360’s unique design combines industry compliant 256AES MACSec encryption for 10Gbps, 40Gbps, 100Gbps and 200Gbps CFP2-DCO coherent DWDM interfaces for mobile backhaul, DCI, cable distributed access architectures and various other transport applications. The ACX6360 provides the versatility to eliminate the two-box solution typically found with packet optical and IP deployed next to each other
    • PTX10002 Packet Transport Router: Scale-out is a key design principle for many cloud providers as they distribute service delivery closer to subscribers for a consistent and high-quality user experience. The PTX10002 is purpose-built for scale-out exchange and cloud architectures with high-capacity, cost-optimised 100GbE interfaces to support growing network traffic demands
  • Juniper’s Metro Fabric also incorporates the previously announced programmable photonic layer, including the Juniper Networks TCX1000 Series Programmable ROADM and proNX Optical Director to bring high levels of flexibility, cost control and multi-layer visibility to packet-optical transport.


“It’s not just the sheer amount of traffic going through the metro network that’s become a real challenge – it’s also the type of traffic we’re starting to see in the metro. Creating new services and keeping up with bandwidth needs requires a new approach to metro networks as the status quo is simply unsustainable. Simplicity is the key to our success so we are excited to see Juniper – with whom we’ve partnered for years – proactively reshaping how the metro serves the evolving needs of our customers.”
