Heavy Networking 561: Modeling Your Network For Intent-Based Assurance With IP Fabric (Sponsored)

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.

Solutions In Search of a Problem

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?

Forward Looking Failures

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

How Developers Can Get Started with Python and Docker


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

Security experts have learned many lessons from 2016 about how cyber warfare not only impacts elections but also has the potential to disrupt everything from energy and education to government services and military operations


For a long time, the ifconfig command was the default method for configuring a network interface. It served Linux users well, but networking is complex, and the commands to configure it must be robust.


SMTP TLS Reporting (TLS-RPT) is a standard that enables reporting issues in TLS connectivity experienced by applications that send emails and detect misconfigurations. It enables the reporting of email delivery issues that take place when an email isn’t encrypted with TLS.


The security of critical infrastructure components requires the governance and support of private sector organizations across various infrastructure sectors. Adopting, implementing, and integrating security practices across federal and private entities is necessary to achieve critical infrastructure cyber resiliency.


Is your system 100% ready to face the severest cyber-attack and mitigate the risk of a possible data breach? If you are unsure about your cyber-safety structure, then it’s time to upgrade it.


Network security firm SonicWall is investigating a coordinated attack in which attackers allegedly exploited vulnerabilities in the company’s products to Continue reading

Keeping Pakistan’s Internet Exchange Points Running

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

AMD builds momentum in server market

The server market is fairly slow to change in all things, and that includes its processor platforms. But lately it's clear AMD's comeback is getting very real.Left for dead four years ago, AMD already has won over the gamers. Its Ryzen series of processors are the go-to choice for system builders on YouTube, whose specialty is building a high-end gaming rig in 15 minutes. But the server market is also taking note.The latest sign came from Mercury Research, which follows the semiconductor market, in particular CPU sales. For the fourth quarter of 2020, Intel held 92.9% market share to AMD's 7.1%, but Intel was down from 95.5% one year earlier in Q4 2019 and AMD was way up from 4.5%. For the server market, that's some rapid growth.To read this article in full, please click here
