Context From The People
Are you ready for the flood of context-based networking solutions? If not, it’s time to invest in sandbags. After the launch of Cisco’s Intuitive Network solution set at Cisco Live, the rest of the context solutions are coming out to play. Granted, some of them are like Apstra and have been doing this for a while. Others are going to be jumping on the bandwagon of providing a solution that helps with context. But why are we here and why now?
Creating Context
The truth is that we’ve had context in the network for decades now. It’s not a part number that we can order from a vendor. It’s not a command that we type into the CLI to activate. In fact, it’s nothing that you can see at all right now, unless there’s a mirror handy.
The context in networks has been provided by people for as far back as anyone can remember. You do it every day without consciously realizing it. You interpret error messages and disregard those that aren’t important. People know how to program VLANs correctly to segment traffic in certain ways. Security context, application context, and more are delivered by breathing, thinking humans.

Stuff The Internet Says On Scalability For July 21st, 2017
Hey, it's HighScalability time:
- 222x: Bitcoin less efficient than a physical system of metal coins and paper/fabric/plastic; #1: Python use amongst Spectrum readers; 3x: time spent in apps that don't make us happy; 1 million: DigitalOcean users; 11.6 million: barrels of oil a day saved via tech and BigData; 200,000: cores on Cray super computer;$200B: games software/hardware revenue by 2021; $3K: for 50 Teraflops AMD Vega Deep Learning Box; 24.4 Gigawatts: China New Solar In First Half Of 2017;
- Quotable Quotes:

sidlls: I think instead there is a category error being made: that CS is an appropriate degree (on its own) to become a software engineer. It's like suggesting a BS in Physics qualifies somebody to work as an engineer building a satellite.

Docker Community Spotlight: Adina-Valentina Radulescu
Adina-Valentina Radulescu, a DevOps/Integration Engineer for Pentalog Romania, has been organizing meetups for not one but two meetup groups.
In February of last year, Adina founded Docker Brasov and Docker Timisoara, and has since done an amazing job creating and fostering a sense of belonging in her community. This month, we’re happy to shine the community spotlight on Adina to learn more about her Docker story.
Tell us about your first experience with Docker.
The first time I heard about Docker was back in 2014. I played around with Docker and I was impressed with the simplicity of integration so I wanted to learn more. I was able to attend DockerCon EU in 2015 in Barcelona where I completed some labs and attended the talks to learn as much as I could about Docker. It was a powerful feeling.
Why did you start Docker Brasov and Docker Timisoara?
I wanted to have a Docker sharing exchange experience when I get back in Romania. I relocated from Timisoara to a beautiful mountain city, Brasov. In Timisoara, I knew people and companies. In Brasov, I knew almost no one. This is why I decided to start the two groups so I Continue reading

How to use Cloudflare for Service Discovery
Cloudflare runs 3,588 containers, making up 1,264 apps and services that all need to be able to find and discover each other in order to communicate -- a problem solved with service discovery.
You can use Cloudflare for service discovery. By deploying microservices behind Cloudflare, microservices’ origins are masked, secured from DDoS and L7 exploits and authenticated, and service discovery is natively built in. Cloudflare is also cloud platform agnostic, which means that if you have distributed infrastructure deployed across cloud platforms, you still get a holistic view of your services and the ability to manage your security and authentication policies in one place, independent of where services are actually deployed.
How it works
Service locations and metadata are stored in a distributed KV store deployed in all 100+ Cloudflare edge locations (the service registry).
Services register themselves to the service registry when they start up and deregister themselves when they spin down via a POST to Cloudflare’s API. Services provide data in the form of a DNS record, either by giving Cloudflare the address of the service in an A (IPv4) or AAAA (IPv6) record, or by providing more metadata like transport protocol and port in an SRV record.
Configuring Private VLANs on Juniper Switches
Basics of Private VLANs
I am sure after reading the above article you will come to know about the basics of the Private VLANs. In this article I am going to cover the Configurational part of the Private VLANs on Juniper Switches, as it is demanded by some of the candidates on the blogs.
I will soon come up the configuration and the topology for the Private VLANs on Cisco and Huawei as well in another article.
A lot of people asking me about the VLANs, before starting with the configuration of the Private VLANs, let me quickly go through the VLANs and Private VLANs.
VLANs : Virtual Local Area Networks
VLANs is the way to partition the various Layer 2 network with in one Local Area Network which simply means that Continue reading
Cisco N1000v Switches
A cisco vswitch that can be used instead of the default VMware DvS to have a similar environment to that of Cisco physical NXOS switches. The control and packet communication can either be carried over VLANs in Layer2 mode or IP addresses in Layer3 mode. The default and Cisco recommended solution is L3 mode.
VMware vSphere vSwitches
Local and Distributed vSwitches server the same purpose as physical switches allowing for VM vNICs to be assigned to specific VLANs. In a production environment it is usual to define a local vSwitch on each ESX host for management and backdoor and have distributed vSwitches shared between hosts for VMs.
BIRD ROUTE SERVER INSTALL | BGP PEER WITH JUNIPER MX
I was recently faced with a challenge whereby I needed to inject 30,000 BGP routes into a test environment for a DOCSIS 3.1 POC. Typically I would use IXIA to form the BGP session and inject the routes. However, all of our IXIA testers were in use thus I needed a quick alternative.
I was already aware of BIRD and it’s use as a route server in a number of IXP environments so figured it would be a good fit. The following steps detail how to install BIRD on Ubuntu and how to instantiate a BGP session with a Juniper MX router.
For more info on BIRD check here
For this install I’m using a VM running Ubuntu server 12.04LTS:
lab@ubuntu-server1:~$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription: Ubuntu 12.04.3 LTSRelease: 12.04Codename: precise
First up we need to enable Linux to support IPv4 forwarding. Two options here; we can either use the sysctl net.ipv4.ip_forward=1 command, although this setting will reset when the server is rebooted. Alternatively we can modify /etc/sysctl.conf to make the change permanent. Edit /etc/sysctl.conf and Continue reading
