The new internet speed record twice as fast as the old one

Everyone wants faster internet speeds. Even people who already have high-speed connections want faster internet, including enterprise workers and IT pros. More speed is what they need, or at least what they would strongly prefer, because the faster data is transmitted between two devices, the faster decisions can be made and actions taken. In the Darwinian digital economy, slow Internet speeds are for laggards and also-rans!So how fast is fast? Some might say the average US internet speed of 99.3 Mbps as measured earlier this year by HighSpeedInternet.com is more than adequate, while an enterprise with a sizable workforce and growing number of connected devices and edge networks would need far more bandwidth.To read this article in full, please click here

IAB Workshop on Measuring Network Quality for End Users

The telephone network had a single task: make human voice conversations work well. IP networks have a more challenging objective: make all kinds of digital transactions work well. From first player shooter games, though video streaming and web transactions through to human conversations. Make 'em all work well. This topic has become one of those long-standing sagas in IETF folklore, and another chapter of the evolving story was written at a recent IAB Workshop on Measuring Network Quality for End Users. Here's my impressions of this workshop.

Packet Capture: What if Less Is More?

Smart packet capture (PCAP) gives analysts the ability to choose the packet evidence they collect and make it retrievable via SIEM.

How Your Network Can Solve Your Digital Dilemma

In the drive to successful transformation, the underpinning computer network on which that change relies is taken for granted to just magically deliver what is needed. But that’s a strategic mistake, suggests Lars Rossen of Micro Focus, who wants the network treated as a product.

Hedge 102: BGP Security with Geoff Huston

Our community has been talking about BGP security for over 20 years. While MANRS and the RPKI have made some headway in securing BGP, the process of deciding on a method to provide at least the information providers need to make more rational decisions about the validity of individual routes is still ongoing. Geoff Huston joins Alvaro, Russ, and Tom to discuss how we got here and whether we will learn from our mistakes.

Cloudflare for Offices

Cloudflare's network is one of the biggest, most connected, and fastest in the world. It extends to more than 250 cities. In those cities, we're often present in multiple data centers in order to connect to as many networks and bring our services as close to as many users as possible. We're always asking ourselves: how can we get closer to even more of the world's Internet users?

Today, we're taking a big step toward that goal.

Introducing Cloudflare for Offices. We are creating strategic partnerships that will enable us to extend Cloudflare's network into over 1,000 of the world's busiest office buildings and multi-dwelling units. These buildings span the globe, and are where millions of people work every day; now, they’re going to be microseconds away from our global network. Our first deployments will include 30 Hudson Yards, 4 Times Square, and 520 Madison in New York; Willis Tower in Chicago; John Hancock Tower in Boston; and the Embarcadero Center and Salesforce Tower in San Francisco.

And we're not done. We've built custom secure hardware and partnered with fiber providers to scale this model globally. It will bring a valuable new resource to the literal doorstep of Continue reading

Dark Mode for the Cloudflare Dashboard

Today, dark mode is available for the Cloudflare Dashboard in beta! From your user profile, you can configure the Cloudflare Dashboard in light mode, dark mode, or match it to your system settings.

For those unfamiliar, dark mode, or light on dark color schemes, uses light text on dark backgrounds instead of the typical dark text on light (usually white) backgrounds. In low-light environments, this can help reduce eyestrain and actually reduce power consumption on OLED screens. For many though, dark mode is simply a preference supported widely by applications and devices.

How to enable dark mode

Log into Cloudflare.
Go to your user profile.
Under Appearance, select an option: Light, Dark, or Use system setting. For the time being, your choice is saved into local storage.

There are many primers and how-tos on implementing dark mode, and you can find articles talking about the general complications of implementing a dark mode including this straightforward explanation. Instead, we will talk about what enabled us to be able to implement dark mode in Continue reading

Watch Out: ISR Performance License

Bill Dagy sent me an annoying ISR gotcha. In his own words:

Since you have a large audience I thought I would throw this out here. Maybe it will help someone avoid spending 80 man hours troubleshooting network slowdowns.

Here’s the root cause of that behavior:

Cisco is now shipping routers that have some specified maximum throughput, but you have to buy a “boost license” to run them unthrottled. Maybe everyone already knew this but it sure took us by surprise.

Don’t believe it? Here’s a snapshot from Cisco 4000 Family Integrated Services Router Data Sheet:

Gigabyte and CoolIT partner for liquid cooled servers

Gigabyte Technology isn’t the first name that comes to mind in data-center hardware. It’s better known as a consumer player, but it is a significant server player none the less, making server motherboards on par with other top names like Supermicro.Now the company has teamed with CoolIT Systems to provide two high-density servers equipped with liquid-cooling technology.The servers, H262-ZL0 and H262-ZL2, are equipped with direct liquid cooling for CPUs designed to support the high-performing but super-hot 280 watt AMD EPYC 7003 (Milan) processors.The servers, based on the company's H262-Z6x family of air-cooled servers, are hyperconverged and very dense, targeting HPC, HCI, in-memory-computing, and scientific-research markets. They both pack four nodes with two sockets each and eight DIMM slots per node in a 2U form factor. To read this article in full, please click here

The search for the optimum network: Don’t let IT vendors sell you on lock-in

How should an enterprise pick products to build its network? Do they look for the best of each product category, knowing this will increase both integration issues and finger-pointing? Do they select the best vendor overall, knowing that this will invite vendor lock-in and compromises in each product category?This issue is as old as networking, and we’ve still not resolved it. How do enterprises decide when to add a vendor in hopes of getting the best technology, and protect themselves from the consequences?SD-WAN buyers guide: Key questions to ask vendors Every network vendor wants to be your only vendor. No network vendor wants to accept responsibility for problems, and most don’t even want to work hard to find out who’s causing them. Big network-equipment vendors have not only fallen behind on innovation, they work to actively stifle it, fearing it could damage their incumbent position. These are the views of enterprises, whether they favor single-vendor networks or best-of-breed.To read this article in full, please click here

Is Network Security Relevant in the Cloud?

Vishal Jain Vishal Jain is the co-founder and CTO of Valtix. Vishal is a seasoned executive and has held engineering leadership roles across many successful startups and big companies in the networking and security space. Vishal was an early member of Andiamo Systems, Nuova Systems, and Insieme Networks, which were acquired by Cisco Systems. Vishal was also responsible for leading the security engineering team at Akamai and built their live streaming service in their early days. Is Network Security Relevant in the Cloud? Short answers: yes, and no. But the details matter. For the last 15 months, we’ve seen a previously unimaginable acceleration in the use of cloud and greater reliance on technology overall, all of which pushes more app efforts to cloud faster than originally planned. This acceleration brings several discussions to a head, but we’re here to talk about network security (netsec). Within netsec in the cloud, there are a few different ways of segmenting, but where this article will draw the line is between protecting users as they access the cloud and protecting apps deployed into the cloud. The former, protecting users, has seen plenty of investment and innovation and is a relatively well-understood problem. The latter Continue reading

Keith’s Law (1)

I sometimes reference Keith’s Law in my teaching, but I don’t think I’ve ever explained it. Keith’s Law runs something like this:

Any large external step in a system’s capability is the result of many incremental changes within the system.

The reason incremental changes within a system appear as a single large step to outside observers is the smaller changes are normally hidden by abstraction. This is, in fact, the purpose of abstraction—to hide small changes inside a system from external view. Keith’s law is closely related to Clarke’s third law that “Any sufficiently advanced technology is indistinguishable from magic.” What looks like magic from the outside is really just a bunch of smaller things—each easier to understand on its own—combined into one single “thing” through abstraction.
If you’ve read this far, you’re probably thinking—what does this have to do with network engineering?
Well, several things, really.

First—the network is just an abstraction that moves packets to its users. Moving packets seems so … simple … to network users. You put data in here, and data comes out over there. All the little stuff that goes into making a network work are lost in the abstraction of the virtual Continue reading

Lightning-fast Kubernetes networking with Calico & VPP

Public cloud infrastructures and microservices are pushing the limits of resources and service delivery beyond what was imaginable until very recently. In order to keep up with the demand, network infrastructures and network technologies had to evolve as well. Software-defined networking (SDN) is the pinnacle of advancement in cloud networking; by using SDN, developers can now deliver an optimized, flexible networking experience that can adapt to the growing demands of their clients.

This article will discuss how Tigera’s new Vector Packet Processing (VPP) data plane fits into this landscape and share some benchmark details about its performance. Then it will demonstrate how to run a VPP-equipped cluster using AWS public cloud and secure it with Internet Protocol Security (IPsec).

Introduction to Vector Packet Processing

Project Calico is an open-source networking and security solution. Although it focuses on securing Kubernetes networking, Calico can also be used with OpenStack and other workloads. Calico uses a modular data plane that allows a flexible approach to networking, providing a solution for both current and future networking needs.

VPP is an easily extensible, kernel-independent, highly optimised, and blazing-fast open-source data plane project that operates between layer 2 and layer 4 of the OSI Continue reading

Simplification through Unification: One Network Across the Entire Multi-Cloud

Two major pillars of VMworld 2021 focus on enhancing productivity and consistency. More than ever, businesses are demanding consistent, secure, and reliable communication between apps and users. What Networking professionals at VMworld want to reinforce is that multi-cloud ops shouldn’t have to slow down due to poor app distribution among workspaces. The network should be durable and secure everywhere. While threats are inevitable, businesses can be prepared by learning how to converge networking, security, and threat detection within the cloud. And that’s exactly what we’re going to teach you at this year’s virtual event.

Valued customers of all different industries have chosen to allow VMware’s multi-cloud ops solutions to guide them through their digital transformation. Susan Wu, Senior Product Marketing Manager, and Aamer Aakhter, Product Manager, are two seasoned VMware leaders who will take you through how customers achieved multi-cloud excellence, and how you can say “Goodbye Compromises Everywhere. Hello Productivity Anywhere,” with this VMworld session.

While simplicity may look different depending upon an organization’s goals, there is one thing that remains constant: performance shouldn’t have to be sacrificed for safety. Your enterprise should be able to streamline the entire multi-cloud to remain agile, productive, and increasingly adaptive against any threat or operational hiccup.

IT portfolios are becoming increasingly Continue reading
