IDG Contributor Network: 5G and the need for speed

Tesla’s “Maximum Plaid” speed mode rockets its new Roadster from 0-60 in 1.9 seconds. If you think that’s fast, go ahead and Google “5G.”5G is Plaid for cellular networking – a next-generation mobile network that promises not only ten-times the available spectrum, for ten-times the download speeds, but across ten-times the devices and with a fraction of the latency.The move from 1Gbps to 10Gbps speeds will support bandwidth-intensive applications like high-definition video and virtual reality, and near real-time connections will enable ultra-low latency applications like autonomous cars, remote surgery and specialized applications within the Internet of Things (IoT).To read this article in full, please click here

Core Switching : Juniper EX8200 Vs Cisco 6800

Today I am going to talk about the Core switching where I am taking two vendors and compare the features between them. Here in the specific switch in the Core we can have two different models for which we are comparing the features. The two Switches are Juniper EX8200 and Cisco 6800 Core switches

Before I start with the models one by one,I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos

So if you are going to compare the switches, both switches are excellent with the high capacity backplane and has so many features. Although Cisco come up with the other model Cisco catalyst 9K which is newly in the market and has huge impact to other vendors.

I already wrote some of the articles on Cisco Catalyst 9K and you can go through the articles below

Cloudflare Apps Platform Update: November Edition

Hello Everyone!

My name is Teffen and I’m a developer on the Apps platform. This is the November edition of our newsletter showcasing the latest platform improvements in payment tools, DNS powered apps, customer comments, and more!

Since our last newsletter, dozens of developers like you have reached out with ideas for new kinds of apps that weren’t yet possible. These are some of my favorite conversations because they help us find out which features should be prioritized. With your guidance, we’ve spent this month meticulously converting our supply of Halloween candy into those ideas. Let’s dive in and see what’s new!

? Paid App Product Enhancements

We’ve made it easier to upsell premium features with product specific options. Customers can try out exclusive features before making a purchase, on any site, even without Cloudflare account! Here’s an example of Lead Box using product specific radio buttons:

Previewing premium features in Lead Box

In this example, a customer can choose to see the newsletter option after choosing the "Pro" plan. Developers can now update the Live Preview in response to this choice. We’ve added new "_product" keyword for this event. Here’s a snippet on how Lead Box handles a customer Continue reading

BGP as a Better IGP? When and Where?

A while ago I helped a large enterprise redesign their data center fabric. They did a wonderful job optimizing their infrastructure, so all they really needed were two switches in each location.

Some vendors couldn’t fathom that. One of them proposed to build a “future-proof” (and twice as expensive) leaf-and-spine fabric with two leaves and two spines. On top of that they proposed to use EBGP as the only routing protocol because draft-lapukhov-bgp-routing-large-dc – a clear case of missing the customer needs.

IDG Contributor Network: How to help your files speak S3

Among the many clouds in the storage sky, Amazon Web Services is the dominant leader by far. The annual AWS re:Invent trade show is taking place in Las Vegas this week, and given how many enterprises have some data in the AWS cloud, the event is expected to sell out.It’s no secret that the cloud is one of today’s top storage industry disruptors, significantly reshaping enterprise IT architectures and investments. Cloud object storage has a well-earned reputation for cutting costs since enterprises can avoid both upfront capital and costly operational expenditures by storing data off-premises. However, the challenges of getting data to the cloud means many enterprises are only getting started on adoption. There is much more growth ahead, as the cloud’s elastic scaling can also deliver agility, but so far, most enterprises are relegating cloud storage for archival.To read this article in full, please click here

Worth Reading: Quad9

In a joint project, IBM Security along with Packet Clearing House (PCH) and The Global Cyber Alliance (GCA) today launched a free service designed to give consumers and businesses added online privacy and security protection. The new DNS service is called Quad9 in reference to the IP address 9.9.9.9 offered for the service. The group says the service is aimed at protecting users from accessing malicious websites known to steal personal information, infect users with ransomware and malware, or conduct fraudulent activity. —CircleIDIn a joint project, IBM Security along with Packet Clearing House (PCH) and The Global Cyber Alliance (GCA) today launched a free service designed to give consumers and businesses added online privacy and security protection.

NetDevOpEd: The right tool for the right job

I’ve been traveling to northern Europe these past few months to meet with various customers, deliver onsite trainings and speak at meetups. I’ve noticed some common themes that crop up no matter with whom I speak. IT professionals are exhausted by the complexity required to manage and maintain their infrastructure. Somehow, networking and server interconnectivity has become this unmanageable complex mess over the past 20 years. And I don’t blame them. As networking has layered on more and more solutions, it becomes hard to separate out the complexity from the deployment.

Normally when I have these conversations, I start at the most basic levels. I focus on two topics that create the most grief for the vast majority of networks:

  1. Layer 1 cabling issues
  2. Typos and misconfigurations

The reason I start there is because resolving these two issues in the data center would eradicate over 90% of all issues that cause late maintenance windows and urgent midnight troubleshooting calls.

At Cumulus Networks, we resolve these issues by rethinking what it means to configure a network device. The most effective solution to both of these issues is simplification of configuration. Because we focus on integration and solution first, we are able Continue reading

Terminology Tuesday Presents: Blockchain

Think of Blockchain as primarily two things.  1) A peer-to-peer technology 2) A way of keeping a public record.

The technological backing of Blockchain is the ability to have many (many) computers host the same information.  Snippets of code (known as blocks) are duplicated and maintained in so many different places rendering fraud impossible.  The fact that each of these blocks is timestamped and unique makes it increasingly challenging to outsmart.  If you’re interested in learning more about the technological specifics there are a number of great resources online including this presentation by Binh Nguyen, IBM’s Blockchain Fabric Chief Architect.

Today, Blockchain is most commonly thought of in connection to Bitcoin as it describes the technology and process that we’ve all come to know as being so secure.  Bitcoin’s past affiliations with illegalities of all sorts have given a bad name to Blockchain but there are many benefits to secure transactions all with a public record as our purchases and currency become increasingly digital.
