Sharing Bandwidth with the Neighbors

By Wayne Hickey – Neighbors, when asked, will typically share a cup of sugar. In some cases, the ‘cup of sugar’ request was, and is, a great way to meet or start a friendly conversation with our neighbors. Waving from 50 feet away, or over a fence, isn’t as inviting or approachable. While being a good neighbor has its benefits, most draw the line for sharing with things like Internet access, typically by simply adding a security key to their home WiFi network. After all, now we’re talking bandwidth, and not sugar!

But with the Internet, every connection is a ‘shared’ connection. Sometimes sharing is done close to your house, a fiber node, headend, or Border Gateway Protocol (BGP) router. BGP is the routing protocol used to route traffic across the Internet Wide Area Network (WAN).

If you want to guarantee that your service is not shared, you must get an enterprise level connection. But even with enterprise level connections, they only guarantee your speed up until the BGP router of your Internet Service Provider (ISP), and as soon as you get on the Internet – you guessed it, its shared and all bets are off!

For cable operators today, coaxial cable is used to deliver broadband services to their existing customers, and will continue for many years. In the cable operator coaxial access network, cable bandwidth is shared among all subscribers in a service group. Service group sizes can vary, but typical coaxial access networks can range in the hundreds (300-500), depending on region. more>

What’s Next for Cable Business Services?
By Darren McKinney – The state of cable business services, fiber versus coax, the addition of mobile services along with the advent of 5G (friend or foe), new service offerings, service level agreements, the move to virtualization, and more, were all hot topics at the recent Light Reading “Future of Cable Business Services” conference.

I have attended this conference for several years, and as it falls at the end of year it’s always a good time to reflect on what this means for the cable industry moving forward. Here are my top takeaways from the 2018 event, and what I’m thinking about heading into 2019.

For years business services represented 20%+ year-over-year revenue growth for cable MSOs – a significant growth engine given MSOs have experienced declining video subscribers (due to OTT competition), and have generally had consolidated revenue growth of 5-10% in recent years. MSOs have experienced higher growth rates in business services with small (100 employees), where these customers require more sophisticated services and competitive service level agreements (SLAs). more>

VodafoneZiggo is revolutionizing the Netherlands’ digital infrastructure
By Leo-Geert van den Berg – Did you know the Netherlands is Europe’s leading country in internet access, broadband connectivity and internet usage on mobile phones?

A lot of tech companies use the Netherlands as a test bed for new solutions and according to recent reports, we are among the frontrunners in the EU in cloud adoption both for businesses and consumers. When it comes to our networks, we rely on their support on our road to success. Here in the Netherlands, we pride ourselves on being open to try new things.

As the largest fixed broadband provider and second largest mobile operator by subscribers in the Netherlands, VodafoneZiggo is looking to the future, with the goal of moving the Netherlands to a renewed network in 2020 – the ‘network of the future’ –  which supports Gigabit speeds of 1.000 Mbit/s. The goal of this network is to align our mobile and fixed connections even closer, so there is a seamless transition between fixed internet and Wi-Fi.

To make networks faster, scalable, and more reliable, they must be built with the intention of becoming fully virtualized. And, thanks to Ciena’s WaveLogic Ai 400G programmable solution, more>

5 Ways DCI Growth is Driving New Innovations in Transport Networking
By Kent Jordan – Data center interconnect (DCI) is at the heart of new global business models, cloud adoption, and digital content delivery and services. Cloud, ICP, and colocation operators are dominating DCI sales, and DCI is becoming more crucial for other industries as well. According to the Equinix Global Interconnection Index, global interconnect bandwidth is forecast to grow to over 8,200T by 2021, which is substantially higher than last year’s projection.

Telecommunications, manufacturing, and banking are all expected to be large contributors to total interconnect bandwidth by 2021. Smaller traffic areas, such as wholesale, retail, and healthcare, are also expected to grow at double-digit rates leading to the need for higher capacity services over time.

Purpose-built, compact, modular systems have sprouted up, offering massive scalability to enable global deployments while reducing operational expenses related to data center space, power, and cooling. These systems offer modularity and pay-as-you-grow scalability for lower traffic scenarios, so enterprises can cost-effectively scale connectivity for cloud services and applications. more>

Dealing with packet networking complexity? It’s time to evolutionize.
By Scott McFeely – As I travel around the world meeting with our customers, I hear time and time again about their continued struggles building and maintaining packet networks.

Today’s TDM and Packet (Ethernet/IP/MPLS) networks are too operationally complex, making them costly to operate, which results in a slower time-to-market and growing inflexibility to successfully address changing customer demands. Networks still lack the automation and agility to rapidly deploy new services.

If operators are to succeed, they need to make changes – now. The traditional approach to building packet networks, from access to metro, just isn’t up to the task.

At Ciena, we believe that the future belongs to the adaptive – those who do more than just recognize the need to modernize, but who see the need to actively “evolutionize” their packet networks toward a more virtual, modular, and automated design. more>

Life’s tough in the great outdoors, especially for packet-optical network gear
By Frank O. Miller – Packet-optical network gear gets pretty pampered in the data center, with regulated temperatures and a whole team of techs on hand to fix any problems. But what happens if you want to put your equipment outside, closer to your customers? How do you know your switches and other gear will be tough enough to survive?

The answer’s simple: regular data center infrastructure won’t be up to surviving in the great outdoors. Instead, you’ll need equipment that’s street-tough, temperature-hardened, and always available – come snow, rain or shine.

So let’s take a moment and think about some of the biggest challenges that could impact your network equipment in the great outdoors…

In mainland Europe, the temperature differentials between summer and winter can be extreme, requiring all network equipment in street cabinets to be temperature hardened. In Germany, for example, many areas experience daily averages of 0°C in the winter, with summer daily averages of around 24°C. In Russia, the swing is even greater, with winter temperatures of -25°C in many regions and summer averages of 30+°C. more>

4 ways an Adaptive Network can overcome today’s challenges and take your network to the next level
By Françoise Pouliquen – There is a relentless push-pull from rapid business and technology change affecting operators today. On one hand, dramatic growth in subscriber demands are driving fronthaul and backhaul traffic and putting networks under intense pressure. While on the other, there’s an industry wide race to develop and commercialize new revenue-generating services, such as IoT use cases and 5G mobile services – and to implement the network technologies and architectures needed to support and deliver them. On top of that, new market entrants, including some of the largest internet companies, are deploying massive-scale network connections that support low-cost data transport between key locations and data centers with unrivalled economies of scale.

The challenges for operators are; how to take exponential traffic growth in stride; how to prepare the network for the next-generation of IoT and 5G use cases; and how to remain competitive on price with large connectivity providers in the market.

Here are four key ways an Adaptive Network can help:

  • Increasing network agility and efficiency
  • Future-proofing the network with industry leading packet-optical solutions
  • Helping avoid vendor lock-in with open networking
  • Driving network innovation in strategic partnership

The Future of the Internet Is Fiber Deep
By Elias Cagiannos – Netflix is the poster child for over-the-top (OTT) content and has no doubt played a large role in shifting the status quo when it comes to our entertainment and viewing habits. The company can be credited with reimagining content distribution — investing in homegrown content and a content delivery network to feed our binge-viewing habits.

However, these habits are primarily supported on MSO networks, which have one of the best internet service products on the market. These companies are focused on the future, making investments in the people, processes and infrastructure necessary to help them match their capabilities to a new generation of users.

Consumer demand for improved viewing options has created an environment where MSOs can’t tolerate service disruptions or quality issues. However, aging coaxial plants, analog repeaters and limited spectrum make meeting customer demand for fast and reliable service a challenge. MSOs recognize this and are already moving in the right direction, but they will advance even faster with fiber deep — the concept by which operators push fiber closer to the end user, which helps improve service. more>

FlexE: 3 reasons network providers are interested
By Helen Xenos – FlexEthernet, or FlexE, is a client interface standard being defined by the OIF that allows for a variety of Ethernet MAC rates (10GbE, 40GbE, nx25GbE) that are decoupled from Ethernet PHY (physical interface) rates.

Wait, what?

You may have heard about FlexE and even read about operators trialing FlexE in their networks, but unless you are intimately involved with standards activities or Ethernet protocol implementation, translating FlexE to its resulting networking value may not be obvious. For most of us, it is only once you start to look at the drivers behind the development and dig into which of today’s challenges it solves, that you can determine whether FlexE is something that makes sense for your network. more>
