The 3rd post in the ‘Automate Leaf and Spine Deployment’ series goes the through the variables from which the core fabric declaration is made and how this transposes into a dynamic inventory. This uses only the base and fabric roles to create the fabric ready for the service sub-roles (tenant, interface and route) to be deployed on top of the fabric at a later stage.
When using a personal VPN at home, one of the biggest problems I’ve faced was the inability to access public streaming services. I don’t care about watching Netflix from another country, I just want to be able to use my local internet connection for this kind of traffic while still encrypting everything else. This problem is commonly known in network engineering as “local internet breakout” and is often implemented at remote branch/edge sites to save costs of transporting SaaS traffic (e.g. Office365) over the VPN infrastructure. These “local breakout” solutions often rely on explicit enumeration of all public IP subnets, which is a bit cumbersome, or require “intelligent” (i.e. expensive) DPI functionality. However, it is absolutely possible to build something like this for personal use and this post will demonstrate how to do that.
The problem scope consists of two relatively independent areas:
Traffic routing - how to forward traffic to different outgoing interfaces based on the target domain.
VPN management - how to connect to the best VPN gateway and make sure that connection stays healthy.
Each of one these problem areas is addressed by a separate set of components.
VPN management is solved Continue reading
There are two different Auroras right now in supercomputing. There is the shape-shifting, legendary, and maybe even mythical “Aurora” and now “Aurora A21” exascale supercomputer that was being built by Intel with “Knights” many core processors and now, if Intel can get them out the door, with a combination of “Sapphire Rapids” Xeon SP processors and “Ponte Vecchio” Xe GPU accelerators, for Argonne National Laboratory. …

In today's podcast, sponsored by IP Fabric, we dive into the IP Fabric Network Assurance platform. This platform gathers network configuration and state, and then builds a network model using a graph database. The result is a "digital twin" of the network that engineers and security teams can use for troubleshooting, to plan and verify changes, for network and security analysis, and to enable closed-loop automation. Our guests from IP Fabric are Pavel Bykov, CEO; and Daren Fulwell, Network Automation Evangelist.

During a few recent chats with my friends in the industry, I’ve heard a common refrain coming up about technologies or products being offered for sale. Typically these are advanced ideas given form that are then positioned as products for sale in the market. Overwhelmingly the feedback comes down to one phrase:
This is a solution in search of a problem.
We’ve probably said this a number of times about a protocol or a piece of hardware. Something that seems to be built to solve a problem we don’t have and couldn’t conceive of. But why does this seem to happen? And what can we do to fix this kind of mentality?
If I told you today that I was creating software that would revolutionize the way your autonomous car delivers music to the occupants on their VR headsets you’d probably think I was crazy, right? Every one of the technologies I mentioned in the statement is a future thing that we expect may be big down the road. We love the idea of autonomous vehicles and VR headsets and such.
Now, let’s change the statement. I’m working on a new algorithm for HD-DVD players to produce Continue reading
Python started in 1991 with humble beginnings focusing on helping “automate the boring stuff.” But over the past few years, we’ve seen Python grow in popularity and become extremely useful not only for scripting but for building modern web applications, machine learning and data science.
The TIOBE Index for February has Python ranked at number 3 on the list. Python has also been in the top 8 rank programming languages for the past 7 years. With such a popular and powerful programming language comes a vibrate and large community.
To that end, we are excited to announce that we are releasing a series of programming language-specific guides to help developers go from discovering the basics of Docker to delivering your images into a production environment and more.
The first in our series is a focus on the Python development ecosystem. We have created a series of tutorials, how-tos, and guides focused on the Python community with much more coming in the future.
We are extremely excited to help Python developers become experts at developing and delivering the next generation of applications using the Docker platform. Below you will find a list of resources and our Python language-specific Continue reading
Internet Exchange Points (IXPs) are a vital element of Internet infrastructure. They can be found at physical and neutral locations where different IP networks meet to exchange local traffic via a switch. Implementing an IXP within a country helps bring faster, more affordable, and better performing Internet to people.
Frustrated by poor quality of service and high-cost connectivity, local Internet stakeholders started off the process of setting up an IXP in Pakistan. With the adoption of the 2015 telecoms policy, there was a new drive to foster interconnection and keep local traffic within the country.
Led by the Pakistan Telecom Authority (PTA), the telecom regulator, the government-initiated consultations on how to set up an IXP. To develop an informed opinion about IXPs, PTA reached out to the Internet Society, the Asia Pacific Network Information Center (APNIC), the local Internet community, and civil society.
The consultations led to the formation of an IXP board; comprised of all stakeholders. The new board decided to establish IXPs at Islamabad, Karachi, and Lahore. The IXP board first set up an IXP in Pakistan at a neutral venue, the Higher Education Commission of Pakistan (HEC), Islamabad in 2016. HEC was ideal because it provided a Continue reading
