No-latency edge computing will snowball

Edge computing, where processing takes place closer to the end user in order to reduce latency, among other things, is set to balloon, according to a researcher.Mobile Edge Computing (MEC) will grow with a high compound annual growth rate (CAGR) of about 50.2 percent per year over the next few years (2016-2023), says Occams Business Research and Consulting, which published research in July.Yet-to-be-launched 5G wireless networks and overall increasing use of data will be among the drivers. Global mobile data should reach 69 exabytes by the close of 2022, up from 8.9 exabytes in 2016, the report says.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Do you have an IT trade craft skills gap?

Do you have, or does your data infrastructure environment have a tradecraft skills gap?Keep in mind that tradecraft is your fundamental skills along with experiences, knowing not just the tools, also the various techniques of what to use when, where, why and how.A tradecraft gap exists when there is work to be done, people are available to fulfill those tasks, yet they lack the skills and experiences to do what is needed. For example, you have a position opening to support some function in your data infrastructure environment; many people are applying for that spot. Perhaps all of those applicants have tons of certificates, yet they lack the skills experience for the position. In other words, there is no shortage of people and their certificates, yet there is a gap between the workers and work to be done.To read this article in full or to leave a comment, please click here

Troubleshooting Cisco Network Elements with the USE Method

I want to draw some attention to a new document I’ve written titled “Troubleshooting Cisco Network Elements with the USE Method“. In it, I explain how I’ve taken a model for troubleshooting a complex system–the USE Method, by Brendan Gregg–and applied it to Cisco network devices. By applying the USE Method, a network engineer can perform methodical troubleshooting of a network element in order to determine why the NE is not performing/acting/functioning as it should.

I ask that if you’re familiar with a given Cisco network platform (or platforms), that you please contribute commands that would also fit into the USE Method! My list is just a start and I welcome contributions from others in order to make it a stronger, more valuable reference.

Please check out the guide: Troubleshooting Cisco Network Elements with the USE Method

What is IPv6 Dual stack? What does IPv6 dual stack exactly mean?

What is IPv6 dual stack ?  From some questions and comments on the website, I understand that there is a confusion about it. So, what does exactly dual stack IPv6 mean ?   IPv6 is not a luxury anymore. It is not avoidable for the Service Providers especially.   The biggest problem for the Service Providers […]

Configuring Voice VLANs

Today I am going to talk about the Voice VLAN. The Voice VLAN feature enables the VLAN to carry the voice traffic. So you have a switch with is connected to the IP Phones, it can be of Cisco Avaya or any other and is connected to the specified VLANs or you can name them Voice VLANs in your network. So when switch is connected to the IP phones, the connected switch sends the voice traffic with layer 3 IP precedence and Layer 2 class of service in short name as COS values which are set as default of value 5. That is the reason because the sound quality of an IP phone call can deteriorate if the data is unevenly sent, the switch supports quality of service (QoS) based on IEEE 802.1p CoS. 

Fig 1.1- Sample Topology- Switch and IP Phone

We can configure an access port with an attached Cisco IP Phone to use one VLAN for voice traffic and another VLAN for data traffic from a device attached to the phone. We can configure access ports on the switch to send Cisco Discovery Protocol (CDP) packets that instruct an attached phone to Continue reading

This was adapted from a post which originally appeared on the Eager blog. Eager has now become the new Cloudflare Apps.

In fact, it has been a constant source of delight for me over the past year to get to continually tell hordes (literally) of people who want to – strap yourselves in, here it comes – control what their documents look like in ways that would be trivial in TeX, Microsoft Word, and every other common text processing environment: “Sorry, you’re screwed.”

Getting Started: Writing Your First Playbook

Welcome to another post in our Getting Started series. Keep reading to learn how to draft a Playbook that can be run in Ansible or Ansible Tower. You can also use it along with the Module Index and the other docs to build your own Playbooks later.

What is a Playbook?

Playbooks are esentially sets of instructions (plays) that you send to run on a single target or groups of targets (hosts). Think about the instructions you get for assembling an appliance or furniture. The manufacturer includes instructions so you can put the parts together in the correct order. When followed in order, the furniture looks like what was purchased.

That's basically how a Playbook works.

The Playbook we're building will install a web server on a target RHEL/CentOS 7 host, then write an index.html file based on a template file that will reside with the final Playbook. You'll be able to take the example Playbook and additional files from this blog and test it out for yourself. While going over the example Playbook, we'll explain the modules that are used.

The author adds instructions for the modules to run, often with additional values (arguments, locations, etc. Continue reading
