On November 1 and 2, Juniper will join a growing community of content and cloud operators, telecom service providers and technology vendors participating in the inaugural Telecom Infrastructure Project (TIP) Summit. Similar to the goals of Open Compute Project in the IT world, TIP’s mission is to explore new approaches to building hyper-scale telecom networks—in particular, to accelerate innovation through the power of open network architectures.

One of the TIP projects in which Juniper is taking a leadership role is Open Optical Packet Transport, an initiative to disrupt the status quo of optical system vendor lock-in by defining an open, packet-optical transport architecture. At the TIP Summit, Juniper will discuss its latest work on this project—and demonstrate a number of new innovations—with customers and partners across the telecom infrastructure value chain.

The TIP Summit arrives at a critical juncture in the evolution of packet-optical transport architecture. Rapid growth of cloud services and content, coupled with increasing global distribution of data centers, is driving operators of all kinds to rethink network architecture and reassess how network capacity and services are activated and managed. Many of the largest global network operators are now articulating the need to migrate away from closed, proprietary optical systems to an open and disaggregated packet-optical transport layer.

As operators seek greater value from the optical value chain, including the flexible deployment and control of best-of-breed components matched to their application needs, the challenges of the proprietary environment that dominates today’s transport networks are increasingly clear:


  • Management and control layer silos: With every optical vendor solution there is an element management system that controls the vendor’s domain. Inevitably the result is an amalgam of management and control silos that make automating or streamlining service provisioning and network resource activation prohibitively complex
  • Inadequate programmability: Many optical vendor systems still do not support open, standards-based APIs such as those based on REST, NETCONF and YANG. Operators are still bound to CLI and legacy management protocols such as TL1 in large portions of their networks, limiting the ability to program transport networks according to application demands from an open, centralized SDN control layer
  • Lack of interoperability: Photonic layer interoperability still lags the packet domain and is therefore an impediment to deploying best-of-breed optical components in a disaggregated model. In addition to TIP, initiatives such as Open ROADM and the DT Terastream interop projects demonstrate the need for more progress towards standards-based optical line-side interoperability


Working in close collaboration with its customers and partners, Juniper’s vision is to overcome these challenges by embracing open, disaggregated packet-optical transport networks managed and controlled in a multi-layer, multi-vendor SDN framework. Of course, most vendors acknowledge increasing demand for open optical networks, but these same vendors have massive installed bases of closed terminals and line systems that represent critical future revenue and profits. In contrast, Juniper is operating with a clean slate, ready to help operators embrace disaggregation and openness today or when it best suits them.

At TIP Summit we will discuss our progress towards enabling a flexible, programmable and interoperable ecosystem of packet-optical functions, sharing our perspective on the following topics:


  • Enabling best-of-breed: By opening up the line system, disaggregating line system functions from coherent transceivers, and advancing line-side interoperability, operators can more easily deploy digital signaling processors (DSPs) with performance characteristics and features that best match their network needs. At Juniper we are bringing solutions to market with this design goal in mind, helping eliminate vendor lock-in and affording operators greater supply chain diversity and control. We are working with TIP ecosystem partners like Lumentum to make interoperable, best-of-breed solutions a reality for our customers
  • Driving automation: Operators want to replicate the level of automation achieved in the data center server environment, where virtual machines and containers can be spun up and down instantly and intelligently, to the packet-optical transport network, where services and capacity need to be activated on demand. At TIP Summit we will share our vision of how JUNOS-based automation, SDN control and (recently acquired) BTI Systems assets are combining to help drive new levels of packet-optical convergence and network automation
  • Optimizing across layers: Hyper-scale cloud networks and global internet backbones can no longer afford the inefficiency and stranded network resources that result from operationally distinct packet and optical transport domains. By integrating NorthStar Controller, proNX Network Manager and other software tools—while embracing microservices-based design principles—Juniper is helping customers gain visibility across the photonic layer to Layer 3 and optimizing LSP and optical link utilization and protection


As the cloud era accelerates, telecom infrastructure will embrace openness, automation and dynamic use of network resources to maximize application performance. Along with other industry initiatives, Telecom Infrastructure Project is helping drive these attributes into packet-optical transport architecture. With increasing investment in optical research and development, combined with proven leadership in switching, routing and network automation, Juniper stands ready to collaborate with network operators and technology partners to build the next generation of packet-optical transport networks.

Juniper Hits A Grand Slam With Its Open And Flexible 400G Solution

by Juniper Employee ‎10-03-2016 09:23 PM - edited ‎10-05-2016 10:36 AM




With the Major League Baseball playoffs upon us, there is no better reference to make for Juniper’s latest coherent DWDM solution than to a grand slam. For those that may not be familiar with this reference, a grand slam is when a player hits a homerun while all the bases are loaded, resulting in the team getting four runs instantly. In other words, it’s a big deal !

Lately, Juniper has been on a roll with the release of several next generation high capacity Coherent DWDM solutions including the 1 x 100G DWDM Coherent MIC and 5 x 100G DWDM Coherent PIC, Optical ILA and Integrated ROADM IPLC. Now, yet again, Juniper hits it out of the ballpark with a 400G coherent solution. Using the industry’s latest innovation in coherent technology, Juniper has developed an open and flexible ultra high capacity 400G Muxponder/Transponder. This 400G solution aka UFM6 (Universal Forwarding Module 6) provides a transport capacity of not 100Gbps, not 200Gbps but 400Gbps on single module. This enables up to 19.2 Tbps capacity on single pair of fiber using 96 x 200Gbps channels. That’s a grand slam !

Now let’s break this down a bit. Starting with the client ports, the UFM6 consists of 10 total physical client ports, either QSFP28 or QSFP+, which can be connected to high capacity routers or switches. While each of the QSFP28 ports support 100GE interfaces, the QSFP+ ports can support multi-service capabilities including 10GE, OC192/STM64, OTU2 and OTU2e. Together, these can enable either 4 x 100GE’s via the QSFP28 ports or 40 x 10G via the QSFP+ ports on the same UFM6 module. The UFM6 also supports a lineside capacity of up to 400Gbps via 2 x 200G Coherent DWDM channels using OTU4 encapsulation. Each lineside DWDM channel is software configurable to 200G 16QAM or 100G QPSK and supports full tunability across the C-band with 50GHz spacing. The UFM6 also supports SD-FEC for maximum performance across metro, regional and long haul spans up to 2000 km. For maximum deployment flexibility, the UFM6 can be supported in 3 different chassis options including the 7801 (1 RU), 7802 (3 RU) and 7814 (14 RU).

Now that we've got all the technical jargon out of the way, let’s talk about the “open” aspects of this 400G solution. The UFM6 supports open northbound interfaces via NETCONF/YANG enabling management through not just Juniper’s own control software (see Juniper's PSM) but also enabling providers to use their own transport controllers to fully manage this solution. This opens the door for operators to customize this solution to their needs and enables new and innovative applications.


To sum it all up Juniper’s new UFM6 400G Muxponder/Transponder enables:

  • Ultra high capacity Packet Optical networks up to 19.2 Tbps
  • Open and automated solutions via NETCONF/YANG interfaces
  • Flexible solutions using software provisionable coherent interfaces 

As service providers, web 2.0’s and enterprises try to keep up with demand for the immense traffic growth on their networks driven by cloud services including (SaaS, PaaS, NaaS etc.) mobile traffic (LTE) and HD entertainment services (HD, Ultra HD etc.) Juniper continues to alleviate capacity bottlenecks with innovative coherent DWDM solutions. However, we are not done just yet, so stay tuned for more groundbreaking technology from your Juniper team as we continue to hit it out of the park !

Working up an appetite for packet-optical capacity? Time to supersize DWDM transport on PTX...Everyone has heard of "too much of a good thing". Whoever came up with that probably wasn't running a network. Those of us trying to keep up with insatiable data demands always need more. More capacity. And more tacos.




What happens when Birkenstocks and Pocket Protectors Get Together?

by Juniper Employee ‎09-28-2016 05:01 PM - edited ‎09-30-2016 01:16 PM

Nerds Rule!!Nerds Rule!!

Product evolution in networking technology is a fascinating place. Years ago it would be hard to imagine the convergence of packet and optical technologies. Those that wear Birkenstocks and start companies in their garages vs, those in white collared shirts with pocket protectors developing products in research & development laboratories of large national telecommunication companies.  They evolved from such different starting places. The DWDM products of today evolved out of the need to expand and improve the telecommunications infrastructure. It took 140 years for the telecommunications network to evolve to its current form.

The Relationship between Multi-Layer Optimization & Multi-Layer PCEs

by Juniper Employee ‎07-13-2016 05:49 PM - edited ‎07-14-2016 07:49 AM


A direct communication channel between the Controller of the optical system and the Controller of the packet system  provides a means of exchanging relevant information so as to enable each domain specific controller to optimize the services for which it is responsible. The data [information] exchanged should be in the form of a common language or data-model that can be used as a trusted source of relevant and real-time domain specific analytics.
