IDG Contributor Network: Are you ready for 5G?

The demand is there. The hype is there. But is the world really ready for 5G?In one sense, the answer is, “absolutely.” The fifth-generation of wireless broadband technology will bring an exponential increase in data speeds that will change how people interact with the internet. For example, download time for an HD movie could go from an hour to a few seconds. 5G can also power up remote surgery. And some say truly autonomous vehicles aren’t possible without it. 5G will connect a higher density of devices, people and things in smaller areas – faster and with lower latency than ever. It promises to inspire an astounding array of innovations and new services.To read this article in full, please click here

The Week in Internet News: Startup Cash for Spy-o-T

Investing in hacking IoT: A startup in Israel has raised $12.5 million in investments to help governments hack the Internet of Things and other technologies, Forbes reports. What could go wrong? Toka says it’ll provide spy tools for whatever device its clients require, with a special focus on the IoT.

Encryption wars, part 348: U.S. FBI Director Christopher Wray says legislation allowing law enforcement agencies access to encrypted devices may be necessary if the government and private vendors cannot come to a compromise, Cyberscoop reports. The FBI has, for several years, complained that its investigations are hampered by encrypted devices, although many security experts say encryption backdoors will make us all less safe.

AI for good: More than 2,000 Artificial Intelligence experts have signed a pledge saying they will not participate in the development of legal, autonomous weapons systems, Gizmodo reports. Autonomous weapons posed a “clear and present danger to the citizens of every country in the world,” the pledge says.

Clamping down: The government in Iraq shut down the Internet for two days in response to protests there, CircleID says. The government ordered the disconnection of the fiber backbone that carries traffic for most of the country Continue reading

Examining Linux system performance with dstat

Want to do a quick performance check on your Linux system? You might want to take a look at the dstat command. Dstat provides valuable insights into Linux system performance, pretty much replacing a collection of older tools such as vmstat, netstat, iostat, and ifstat with a flexible and powerful command that combines their features.With this one command, you can look at virtual memory, network connections and interfaces, CPU activity, input/output devices and more. In today's post, we'll examine some dstat commands and see what they can show you about your systems. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] Dstat options and defaults First, let's start with a fairly simple command. With the dstat -c (CPU) option, dstat displays CPU stats. In the example below, we're asking for two-second intervals and six reports.To read this article in full, please click here

Network Break 194: Amazon Spooks Switch Vendors; Big Switch Brings VPCs On Prem

Take a Network Break! Today we’re joined by guest John Fruehe. Amazon sent shock waves through the networking industry on rumors it might sell whitebox switches to the enterprise. The cloud giant says it has no current plans, but we examine other ways AWS might get into your network.

AWS adds EC2 instances to its Snowball edge storage device, and Big Switch Networks rolls out new software to enable VPC-like networking in your private data center.

A British government agency dings Huawei on national security, Deutsche Telekom joins Linux Foundation Networking, and Cato Networks adds identity routing to its SD-WAN offering.

Last but not least, Cisco releases more than two dozen security advisories, and Microsoft rakes in the money in its fourth quarter and fiscal 2018 financial reports.

How SD-WAN will make the cloud much, much bigger

Though I no longer actively participate in it as a pioneering player in the networking space I have always kept a watchful eye on the market and I am seeing yet another disruptive force known as SD-WAN (Software-Defined Wide-Area Networking) finally gaining momentum.For starters, SD-WAN is an extension of Software-Defined Networking (SDN). As the term implies, SDN aims to automate (virtualize) various network functions that are currently touch-heavy.[ Related: SD-WAN: What it is and why you will use it one day ] Network architects talk about separating the control plane from the data plane ad nauseum but that is just the starting point. The ability to virtualize numerous network functions from a central location and thus create an abstraction layer in a manner that is custom-tailored for each enterprise – and, by extension, perhaps for each user - has been the Holy Grail of networking for years if not decades. Tom Nolle, president of CIMI Corporation and a longtime proponent of all things SDN, is spot on when he states that: "SD-WAN is absolutely critical, because it is the vehicle most likely to bring true virtualization to networking. Without virtualization in the network, virtualization in the Continue reading

Juniper QFX | VMware NSX Edge Gateway | BGP Peering

In this post, I’m going to explain how to establish a BGP peering session between Juniper QFX Series Switches and VMware NSX Edge Service Gateway. VMware NSX provides many features and services, one of which is dynamic routing via the use of an ESG. Typically, ESGs are placed at the edge of your virtual infrastructure to act as a gateway. There are two primary deployment options, stateful HA or non-stateful ECMP. In this example, we’re looking at the ECMP deployment option.

Overview

We have a pair of Juniper QFX5110 switches that we will configure to enable EBGP peering with each NSX Edge Gateway. We also have a pair of NSX Edge Gateway devices that are placed at the edge of a virtualized infrastructure. Each QFX has a /31 point-to-point network to each ESG. These networks are enabled via 802.1q subinterfaces which provide connectivity across the underlying blade chassis interconnect modules.

We’ll start by configuring BGP on our NSX Edge Gateways.

Via global settings for ESG1, we need to set a Router ID. The router ID is used to identify from where a packet is received.

Bolstering my Software Development Skills

I recently tweeted that I was about to undertake a new pet project where I was, in my words, “probably going to fall flat on my face”. Later, I asked on Twitter if I should share some of the learning that will occur (is ocurring) as a result of this new project, and a number of folks indicated that I should. So, with that in mind, I’m announcing this project I’ve undertaken is a software development project aimed at helping me bolster my software development skills, and that I’ll be blogging about it along the way so that others can benefit from my mistakes…er, learning.

Readers may recall that my 2018 project list included a project to learn to write code in Golang. At the time, I indicated I’d use Kubernetes and related projects, along with my goal of making more open source contributions, as a vehicle for helping to accomplish that goal. In retrospect, that was quite ambitious, and I’ve since come to the realization that there are a number of “baby steps” that I need to take before I am ready to use a large software project like Kubernetes as a means to help improve my coding skills.
