End-to-end data, analytics key to solving application performance problems

As someone who used to work in corporate IT, I can attest to the fact that in general, workers and IT are at odds most of the time. Part of the problem is the tools that IT uses has never provided the right information to help the technical people understand what the user is experiencing.That is why help desks are often referred to as “the no help desk” or “helpless desk” by the internal employees. Users call the help desk when an application isn’t performing the way it should, and IT is looking at a dashboard where everything is green and indicates things should be working.Traditional network management tools don’t provide the right information The main reason for this mismatch is that traditional network management tends to look at the IT environment through the lens of infrastructure instead of what the user experiences. Looking at specific infrastructure components doesn’t provide any view of the end-to-end environment, leading to a false sense of how things are running.To read this article in full, please click here

ISOC has goals at TNC18

This week is TNC18, the largest European research and education networking conference, which is being held at the Lerkendal Stadium in Trondheim, Norway – the home of current Norwegian Football Champions Rosenborg BK. Of course we’re actually in a conference centre underneath one of the grandstands and not on the pitch, but this is still a premier event that brings together managers, network engineers, and researchers from R&E networks in Europe and the rest of the world.

The Internet Society is not only one of the conference sponsors, but has a significant role in the programme as well. Our colleague Karen O’Donoghue on Monday spoke about NRENs and IoT Security in the ‘What’s Coming Next In Privacy Innovation‘ session, where she’s discussing the security and privacy challenges of burgeoning numbers of IoT devices and how these will impact R&E communities. ISOC is encouraging the development of best practices through the Online Trust Alliance’s IoT Security & Privacy Trust Framework, and this is a good opportunity to discuss how the NREN community can take the lead in adopting good operational practice.

Karen will also be talking about Time and Security during the ‘Security‘ session on Tuesday. Continue reading

IBM launches new availability zones worldwide for hybrid enterprise clouds

CIOs and data center managers who run large hybrid clouds worldwide have a good chance of hearing IBM knock on their doors in the next few months.That's because IBM is opening 18 new "availability zones" for its public cloud across the U.S., Europe, and Asia-Pacific. An availability zone is an isolated physical location within a cloud data center that has its own separate power, cooling and networking to maximize fault tolerance, according to IBM.Along with uptime service level agreements and high-speed network connectivity, users have gotten used to accessing corporate databases wherever they reside, but proximity to cloud data centers is important. Distance to data centers can have an impact on network performance, resulting in slow uploads or downloads.To read this article in full, please click here

Supermicro is the latest hardware vendor with a security issue

Security researchers with Eclypsium, a firm created by two former Intel executives that specializes in rooting out vulnerabilities in server firmware, have uncovered vulnerabilities affecting the firmware of Supermicro servers. Fortunately, it’s not easily exploited.The good news is these vulnerabilities can be exploited only via malicious software already running on a system. So, the challenge is to get the malicious code onto the servers in the first place. The bad news is these vulnerabilities are easily exploitable and can give malware the same effect as having physical access to this kind of system.“A physical attacker who can open the case could simply attach a hardware programmer to bypass protections. Using the attacks we have discovered, it is possible to scale powerful malware much more effectively through malicious software instead of physical access,” Eclypsium said in a blog post announcing its findings.To read this article in full, please click here

Network Break 188: Microsoft Buys More Friends, Huawei is No2, Tofino plus more Politics

Take a Network Break! Its the virtual stroopwafel edition this week. Drew is on annual leave and travelling to Amsterdam, don t panic he will be back next week with bags of virtual stroopwaffel s. Mike Fratto is c-hosting to keep the show flowing. 

Microsoft buys a bunch of new developer friends, Arista get some P4 & Tofino, Micron is embroiled in US-China politics to balance ZTE, Huawei is No2 Enterprise networking vendor, Fortinet buys Bradford Networks and more.

Sponsor: InterOptic

InterOptic offers high-performance, high-quality optics at a fraction of the cost. If you’re not doing optics correctly, you’re going to pay for it upfront (and then later too). Don’t be fooled by lesser optics. The difference between generic third-party and brand-equivalent optics matters.

IoT has an obsolescence problem

The Internet of Things (IoT) is a long way from becoming a mature technology. From wearable devices to industrial sensors and consumer conveniences, IoT vendors and users are still trying to figure out what the technology does best as it grows into a $9 trillion market by 2020 (according to some estimates).And yet, IoT is somehow already faced with a huge and growing problem of obsolescence. The problem, ironically, lies in the “things” themselves.Apple Watch: A premature antique Don’t believe me? Consider the solid gold Apple Watch Edition, launched in 2015 and sold for $10,000 to as much as $17,000 a pop. A traditional watch at that price point would be expected to last decades, perhaps even generations as it turns into a family heirloom. But with the announcement of Apple Watch OS 5 at the company’s World Wide Developers Conference this week, the original version of these fancy timepieces can no longer keep up. They simply won’t run the latest version of the operating system due out this fall, and they won’t have the features of brand-new Apple Watches that cost a tiny fraction of that amount.To read this article in full, please click here

CLIC Québec – L’heure du déclic pour la découverte et l’accès en ligne au contenu culturel québécois

Dans un contexte de renouvellement des politiques culturelles du Québec et du Canada à l’ère du numérique, ISOC Québec a lancé le projet « CLIC Québec » grâce à la subvention Beyond The Net octroyée par l’Internet Society en juillet 2017. Ainsi, depuis bientôt un an, ISOC Québec oeuvre à travers « CLIC Québec » d’une part à sensibiliser les décideurs politiques et les utilisateurs finaux et d’autre part à identifier et valoriser les bonnes pratiques des milieux culturels en matière de diffusion, de promotion et d’accès en ligne aux contenus et produits culturels locaux.

Profitant de la tenue du 1er Forum sur la Gouvernance d’Internet au Québec (FGI Québec), qui coïncidait avec les célébrations des 25 ans de l’Internet Society en septembre 2017, ISOC Québec a organisé un atelier intitulé Cultures en réseaux et découvrabilité des contenus locaux au cours duquel une soixantaine de participants (professionnels de la culture, experts et consultants en politiques culturelles, spécialistes des métadonnées et du Web sémantique, chercheurs/universitaires, citoyens et utilisateurs finaux) ont identifié ensemble dix pistes d’action susceptibles d’accroître la présence et le rayonnement des contenus culturels québécois sur Internet.

Pour mobiliser davantage les acteurs des différents secteurs des industries culturelles québécoises Continue reading

What is digital twin technology? [and why it matters]

Digital twin technology has moved beyond manufacturing and into the merging worlds of the Internet of Things, artificial intelligence and data analytics.As more complex “things” become connected with the ability to produce data, having a digital equivalent gives data scientists and other IT professionals the ability to optimize deployments for peak efficiency and create other what-if scenarios.[ Click here to download a PDF bundle of five essential articles about IoT in the enterprise. ] What is a digital twin? The basic definition of a digital twin: it’s a digital representation of a physical object or system.

Switch stacking for campus design: There’s a better way

We often receive the following campus design question: “do you support switch stacking?” This is a fair question, as many of the legacy vendors have promoted stacking designs for the past decade. It’s popular enough that people ask for it, so we must support it, right?

Well, the popular option isn’t always the best one, and switch stacking designs are a very good example of that philosophy. So when people ask if we support stacking, we think to ourselves “heck, no” before politely telling them that we do not because better options exist.

“Perfection is attained, not when there is nothing more to add, but when there is nothing more to take away.”

At Cumulus Networks, we believe that simplicity is the corner-stone of network design.

Or, to say it another way, complex designs fail in complex ways (shoutout to Eric Pulvino for that quote!). Our former Chief Scientist, Dinesh Dutt, gave an excellent explanation around the importance of simple building blocks in his Tech Field Day 9 Presentation (6min 50 seconds in).

Let’s address a little history on switch stacking and then break down the major technical downfalls of a stacking design, the stacking protocol itself, Continue reading
