IDG Contributor Network: Self-healing SD-WAN removes the drama of high-availability planning

My humble beginnings Back in the early 2000s, I was the sole network engineer at a startup. By morning, my role included managing four floors and 22 European locations packed with different vendors and servers between three companies. In the evenings, I administered the largest enterprise streaming networking in Europe with a group of highly skilled staff.Since we were an early startup, combined roles were the norm. I’m sure that most of you who joined as young engineers in such situations could understand how I felt back then. However, it was a good experience, so I battled through it. To keep my evening’s stress-free and without any IT calls, I had to design in as much high-availability (HA) as I possibly could. After all, all the interesting technological learning was in the second part of my day working with content delivery mechanisms and complex routing.To read this article in full, please click here

Worth Reading: BGP DFZ Security

If a certificate is published with an incorrect set of number resources then there is the possibility that its subordinate certificates cannot be validated, which, as we’ve noted has implications for the reachability of services on the Internet through the connection to the routing system. Thus, certificate issuance is not without its potential legal liabilities, and it is not unusual for certificate authorities to limit their liabilities. —Geoff Huston @CircleID

Cloudflare’s network boosts security and performance for IBM Cloud customers

Cloudflare’s network boosts security and performance for IBM Cloud customers

Today our partner IBM® announced the general availability of Cloud Internet Services (CIS) Enterprise. It marks a significant step forward in the partnership that we announced at the IBM THINK event in March.

CIS delivers security and performance to IBM Cloud® customers’ internet applications. It brings together Cloudflare’s 150+ points of presence with IBM Cloud’s 60 data centers, stopping attacks before they can even reach the IBM Cloud. CIS Enterprise is integrated into IBM Cloud, allowing IBM Cloud customers to set up and manage Cloudflare’s DDoS mitigation, web application firewall, smart routing and highly customizable load balancer, all from within the IBM Cloud user interface.

Our Network Map (as of 10/18/18). Click here for the latest version

We thought it timely to give a refresher on how Cloudflare’s network supports IBM Cloud customers. The network is designed to meet requirements of the most demanding enterprise customers. It is based on an architecture that differentiates it from legacy CDN, DNS and DDoS-mitigation services to ensure that internet applications stay online, even in the face of extremely high volume attacks or legitimate traffic spikes.

Cloudflare’s network of data centers, distributed across 74 countries (including 22 in China), has a network Continue reading

Using nmap on your home network

Nmap, the "network mapper" has long been used on corporate networks to collect information on desktop systems and servers. The tool provides information on the systems and services that are running (i.e., open ports). It can also help to identify rogue systems and vulnerabilities. Nmap makes it easy to detect changes as well as new systems on the network. Typical uses include: host discovery -- probing by IP address and providing information on the systems that respond port scanning -- identifying services that are available for use version detection -- identifying applications and their versions OS detection -- determining the operating system along with some hardware characteristics Sysadmins have been installing nmap on Linux for more than 20 years. Originally released in 1997, nmap has since that time become available for Windows and other Unix variants as well. In fact, it's considered a standard security tool and is a free and open source security scanner. It's typically used in corporate settings for collecting information on systems and doing security analysis.To read this article in full, please click here

Is the IoT in space about to take off?

Space may not be the final frontier for the Internet of Things, but evidence is mounting that it could be the technology’s next golden opportunity. While we’re still a ways away from the IoT in space becoming a commercially viable mainstream technology, a variety of companies are pushing the envelope in two significant ways.First, companies are working to realize the promise of satellite-powered networks that would bring the Internet of Things everywhere on earth. Second, vendors — and NASA — are exploring actual IoT applications and use cases beyond Earth’s atmosphere, in satellites and rockets.To read this article in full, please click here

Oracle Cloud Infrastructure Is Proud to Join the Internet Society

The Internet has become the world’s most powerful tool for commerce, communication, and innovation because of a commitment from its stakeholders to work collaboratively to make it highly performant and more secure.

At Oracle Cloud Infrastructure, we take that commitment to a better Internet seriously and want to align ourselves with other organizations that share a similar vision. That is why I am so proud to announce our partnership with the Internet Society, a global non-profit organization dedicated to the open development, evolution and use of the Internet.

I have spoken previously about how highly I regard the Internet Society’s new CEO, Andrew Sullivan, but my admiration for the work being done extends throughout the organization. This is why it is important to me that our relationship with the Internet Society is more than ceremonial. We want to roll up our sleeves and get to work because there is much work to be done.

One area we feel we can help is in security. The Internet is a trust-based network of networks and it’s consistently under attack by bad actors. We believe there is simply greater strength in the collaboration of the good guys and gals. Security is a Continue reading

Lenovo, Scale partner for hyperconverged edge servers

OEM Lenovo and hyperconverged infrastructure (HCI) platform developer Scale Computing have partnered to offer an out-of-the-box HCI platform specifically for edge computing deployments.Dubbed the Scale Computing HC3 Edge Platform on Lenovo Servers, the solution is an integration of Scale's HC3 software platform — what it calls “a data center in a box” — on Lenovo server hardware. HC3 brings together compute, storage, and virtualization into a comprehensive system with automated management.The Lenovo/Scale solution provides "edge infrastructure that has the capacity to run various IT and OT workloads, is space-conscious, and can be managed at each individual location by generalists," said Wilfredo Sotolongo, vice president and general manager of IoT for Lenovo's data center group, in a statement.To read this article in full, please click here

BrandPost: How 802.11ax Improves the Experience for Everyone

The next advance in Wi-Fi, 802.11ax, is fast approaching. As we seek to raise the performance bar yet again for the sixth generation of Wi-Fi, the traditional techniques used in 802.11n and 802.11ac – wider RF channels, more MIMO antennas, higher QAM modulation – have been pushed almost to the limit, and it’s time to look for new ideas.802.11ax introduces techniques for ‘massive parallelism,’ especially OFDMA, multi-user MIMO, and ‘BSS coloring.’ All of these require the access point to make control decisions that have a significant effect on network performance, a new emphasis for Wi-Fi that will move access point networks closer to cellular base station infrastructure in terms of functionality.To read this article in full, please click here

The Easiest Way to go Faster is to go Faster

400G-blog-image

Why 400G Ethernet? In one sentence, because the easiest way to go faster is to go faster.
Over time, Ethernet speed transitions have been the primary driver for improving both the throughput and price-performance of datacenter networks. 400G Ethernet is the next major transition on this journey. While 100G Ethernet is still ramping up rapidly this year and next, it is projected that by the end of 2021 400G Ethernet will represent the majority of Ethernet bandwidth shipped.
