Ahead In the Clouds

JayBy Jay Gill

Principal Product Marketing Manager

For the past few years hyperscale Internet content providers (ICPs) have been attracting attention because the global network investments they are making to interconnect their data centers are outpacing investments being made by traditional service providers. Once again in 2015, ICP investments in data center interconnect (DCI) grew fastest, more than doubling the growth rate of every other segment, according to Ovum’s recently published Market Share Report: 4Q15 and 2015 Data Center Interconnect (DCI). The ICP segment is now 34% of the global DCI market, and over 50% of the largest market, North America.

It should come as no surprise that competition to serve this large and fast-growing market is fierce. But perhaps some observers might be surprised to learn that Infinera has not only maintained its strong lead in the market, which it first gained in early 2014, it has increased that lead dramatically. Per Ovum, Infinera finished 2015 with a 29% share of the ICP DCI market, 8.5% higher than a year earlier and 10% higher than the nearest competitor.

How has Infinera been able to grow DCI share so dramatically among ICPs? (more…)

Solving Scale Challenges in Mexico – One of Latin America’s Fastest Growing Markets

Martinez_headshotBy John Martinez, Sr. Marketing Specialist

According to emarketer.com, it is estimated that in 2015 there were over 60 million Internet users in Mexico, which represents about a 50% penetration rate.  Compared to other countries this rate is low, but according to eMarketer, Mexico’s Internet adoption rate is rapidly growing with a 9.4% year-over-year expansion in 2015. The resulting upward trend in bandwidth consumption, combined with the increase from bandwidth hungry applications, is creating capacity constraints in many of Mexico’s largest cities.

To solve the challenge of continuous growth in bandwidth demand, service providers delivering mobile and fixed-line services to Mexico’s metropolitan areas have a real and urgent need for scalable information and communications technology (ICT). Infinera’s Intelligent Transport Networks have been proven to provide the scalable network bandwidth service providers need when confronted with rapid growth in demand.

To demonstrate the benefits of Infinera’s end-to-end packet-optical solutions for service providers in Mexico, we recently showcased our Infinera Express, the technologically advanced mobile innovation lab, to more than 400 customers and prospective customers. (more…)

Reducing Cost and Latency in Ring-based Multi-Layer Networks (AKA Lessons Learned on the Circle Line)

ChrisLiouBy Chris Liou, VP Network Strategy

In the London rail system, there is a line called the Circle Line that ferries riders past many famous tube stops in central London – Victoria Station, Paddington, etc. On my last trip to London, I got on the train going the wrong direction. So instead of only needing to transit eight or so stops, I ended up going the other way around the ring, going through 15 or so stops, resulting in a considerable delay, not to mention the stress and anxiety that went along with knowing I might miss my flight home.

In transit systems, it’s a well-known fact that in general you want to avoid as many transit stops as possible – in air travel that means direct flights are preferred over multi-hop flights with layovers, and for the Circle Line, it sure would be great if they had rails that could cut across the ring to create shortcuts. Imagine the savings in total travel time that would come from eliminating transit point delays (where passengers get on and off) as well as potentially reducing actual time in motion. From a passenger’s perspective, an ideal transit system would always provide a single hop to one’s final destination. This would reduce the size of the railcars needed, because each one could be sized for the number of people going from station A to station Z, but the cost of realizing such a vision on the Circle Line is clearly impractical and cost-prohibitive never mind the fact that it would be extremely challenging to engineer. So, instead, we live with the current model of a large-capacity train, sized to accommodate passengers getting on and off at various stations, enduring the “cost” of going through each station en route.

In many ways, multi-layer ring-based Internet protocol (IP)/optical networks have similar challenges. If we consider a physical fiber-based ring that interconnects multiple cities, and the variable/bursty traffic demands that might go between any two cities, it makes sense to deploy IP routers at each location. These routers not only terminate services or traffic at these sites, but also act as intermediate transit nodes for traffic that is just passing through. This works well for up to several nodes, but starts to become inefficient as the percentage of transit traffic at a router site becomes too large, proportionally to the add/drop traffic. At some point, creating a partial mesh topology becomes highly desirable for diversity as well as traffic optimization reasons. But that’s a topic for another day. For this discussion, let’s consider a fixed physical fiber ring, because many fiber rings with 10 or fewer sites exist today, and an assumption of traffic following a general “anywhere-to-anywhere” pattern with a mix of small and large flows.

There are multiple options for building such a fiber ring-based network. The simplest way is to deploy routers and use static point-to-point wavelengths (via wavelength-division multiplexed or WDM optics) between each pair of neighboring nodes, very much like the Circle Line model. While simple to engineer, this method incurs a high proportion of transit traffic at each router location, and is typically the most expensive to scale. From a multi-layer networking perspective, it is a somewhat rudimentary approach that does not provide network operators with ways to optimize the optical transport layer. As such, let’s look at three multi-layer options that leverage a flexible optical transport layer:

  • Option 1: routers and wavelength-granular switching using WDM/reconfigurable add-drop multiplexers (ROADMs)
  • Option 2: routers and optical transport network (OTN) switching (WDM/OTN)
  • Option 3: routers and packet-aware OTN switching (WDM/P-OTN)

ANGA COM Takeaway: Technologies That Are Enabling Increased Network Flexibility and Spectral Efficiency

GaylordHartBy Gaylord Hart

Director of MSO Market Segment

Recently I attended the ANGA COM Exhibition and Congress in Cologne, Germany, the largest broadband and cable conference in Europe and growing, with over 1800 attendees and 450 exhibitors from 89 countries this year. This conference continues to be a focal point for the international cable telecommunications community.

As always seems to be the case these days, much of the conference was focused on how operators can continue to increase broadband speeds and deal with the continuing explosion in bandwidth demand.  DOCSIS 3.1 was a major topic of discussion, but this year symmetrical DOCSIS was all the buzz, with its promise for radically increasing return path capacity and speed.

As part of the ANGA Congress technical session “FTTX – Stepping into the Gigabit Society,” I gave a presentation entitled “FlexGrid Optical Networks and Terabit Super-Channels.” The focus of my presentation was on increasing network flexibility and spectral efficiency by using flexible grid (FlexGrid) line systems and dense wavelength-division multiplexing (DWDM) terabit (T) super-channels. It’s not possible today to implement a terabit super-channel with just one or two waves due to constraints on silicon speed, so the fastest time to market and most practical approach will use a multi-carrier solution. Using 100 gigabit per second (100G) technology per constituent wave, implementing such super-channels is possible today.

However, the multi-carrier approach leads to increased complexity.  (more…)

New Metro Product Naming Reflects Significant Integration Progress

Karl ThedeenKarl Thedéen

Sr. Vice President, Head of Metro Business Group

Almost a year ago, Infinera expanded its offerings to include the technologies, portfolio and resources of Transmode. Since then, we have rapidly integrated the two companies’ product portfolios into a cohesive end-to-end optical portfolio with best-in-class products for the three major optical networking areas of metro, long-haul and data center interconnect. This integration includes direct coherent 100G interoperability between the TM-Series and the DTN-X XTC Series, packet-optical integration and a common network management system.

To reflect the great progress we’ve made in bringing our end-to-end portfolio closer together, we’ve made the decision to rename the TM-Series and TG-Series as the XTM Series and XTG Series respectively, and to rename our network manager TNM as DNA-M. This new naming highlights the tighter integration of the XTM Series with the DTN-X XTC Series, the integrated end-to-end management through Infinera Digital Network Administrator (DNA) and the commitment to the future of the XTM Series, XTG Series and DNA-M within the Infinera portfolio.

This is a small but very significant change that we’ve taken our time to announce to ensure we had made the progress required to justify the new naming. I’m delighted that we’ve achieved our goals and made the change. Keep watching Infinera for more announcements across our unique end-to-end portfolio!

Guest Blog: SubOptic 2016 – A New Wave of Next-gen Transport Technologies Shaping the Submarine Networks of the Future

Larry Schwartz SeabornBy Larry W. Schwartz

Chairman & Chief Executive Officer, Seaborn Networks

Dubai, one of the world’s largest and most cosmopolitan cities, was buzzing recently with telecommunications experts during the SubOptic 2016 conference. For all of us at Seaborn Networks, SubOptic was a momentous occasion as we showcased our state-of-the-art Seabras-1 cable between New York and São Paulo.

Seaborn is transforming global communications as the preeminent developer of submarine cable systems with an independent cable operator model. Seabras-1 is the first-ever direct fiber optic cable between the financial and commercial centers of Brazil and the United States. With a current maximum design capacity of 72 terabits per second (Tb/s), the system also has multiple branching units for future expansion throughout North and South America.

SubOptic provided an excellent forum for submarine network operators like us and vendors like Infinera to promote solutions, foster debate, exchange ideas and act as educational resources for the entire submarine telecommunications industry. Infinera has recently announced their multi-terabit Infinite Capacity Engine, and the more I learn about it the more I am convinced that this new optical engine and the array of new technologies enabled by it will play a crucial role in shaping future submarine networks.

In its quest to satisfy the ever-growing demand for high-capacity bandwidth, the transport industry is moving toward flexible grid architecture while deploying super-channel technology. High-capacity bandwidth is important for subsea cable communications. In conjunction with Infinera, today we have 500 gigabit per second (Gb/s) FlexGrid super-channel solutions on a single line card. Infinera’s new Infinite Capacity Engine enables multi-terabit super-channels.

The true metric for fiber capacity in subsea applications is the capacity-reach product. (more…)
