Bufferbloat in Action due to Covid-19
Four people now live and work in my home 24×7; my wife Andi, her mother, my daughter and myself. Many of you now live in similar situations.
Very occasionally, everyone will have network trouble, such as occurred to us this morning. Sometimes it is our “last mile” connection: it is easy to see these failures in our cable modem log. (Often available by looking at the address 192.168.100.1, which seems to be the default address for cable modems.). Occasionally it can be the ISP (in our case, Comcast), either due to some routing failure or DNS failure. These can be harder to diagnose.
Bufferbloat, however, is insidious. It comes and goes, and most users have been “trained” to ignore temporary bad behavior over many years. When you go to diagnose it, you usually stop the operation that is causing it. This blog has recorded our efforts to fix bufferbloat. Now that there are many more people at home at the same time trying to do more demanding applications, this problem is much more common. Other people in your home can inflict the bufferbloat problem on you without you or they understanding what is happening.

The Management Plane of Multi-Cloud Networking – Aviatrix CoPilot
Recently, Aviatrix launched a new product called CoPilot to address the dire need of operational visibility in multi-cloud networking. This piqued my interest because the none of the Cloud Service Providers (CSPs) provide any topology tools for end-to-end visualization, monitoring and troubleshooting. So I decided to attend the launch event. Some of the biggest challenges … Continue reading The Management Plane of Multi-Cloud Networking – Aviatrix CoPilotNext Generation Cognitive Networking
Just a decade ago, public cloud titans Amazon Web Services and Microsoft Azure Cloud, became synonymous with elastic scaling, and software provisioning through APIs. This was a phenomenon that didn’t exist within closed legacy systems.
Private clouds, by contrast, saw the relevance of enterprise customers recreating an infrastructure based on public cloud principles operating at a smaller scale. In an ideal world, both clouds would allow application developers to create and choose where to deploy applications without trade-offs. Arista pioneered technology development in this cloud networking category and today with Covid-19 restrictions driving millions of users to work-from-home, there are tremendous pressures on network access and bandwidth.

Deploying IPv6 in Public Clouds is Easy
One of the hands-on exercises in our Networking in Public Cloud Deployments online course asks the attendees to deploy a full-blown virtual networking solution with a front-end (web) server in a public subnet, and back-end (database) server in a private subnet.
The next (optional) exercise asks them to add IPv6 to the mix for a full-blown dual-stack deployment.
On Duplicates
Packet duplication wastes bandwidth and can lead to significant network performance degradation or even outages.
In multicast routing, packets are replicated by the network, so there is always a fundamental risk of duplicate traffic. Special safeguards exist to avoid …
On this 50th Earth Day, We Are Using The Internet To Change The World
50 years ago when the first Earth Day happened, the networks that would later form the Internet were only beginning.
20 years later, when Earth Day 1990 turned the celebration into a global event, the World-Wide Web existed only as a single website in Switzerland.
Today, the Internet is our lifeline. In a world locked down by coronavirus, the Internet is how we connect. It is how we communicate, collaborate, and create together. It is how we work and how we play. And on this Earth Day 2020, we will use the Internet to celebrate the 50th anniversary.
Each and every day, we are using the Internet to respond to climate change and other environmental issues:
- Scientists are collaborating and sharing their knowledge. They are finding new solutions and creating new programs.
- Projects are crowdsourcing vast amounts of data from regular people around the world (ex. Earth Challenge 2020)
- We are sharing ideas and learning from each other.
- Policy makers are learning what works in other regions.
- We are avoiding unnecessary travel and reducing our carbon footprint.
- Activists are joining in global movements.
- We are seeing that what affects someone in one part of the world may affect us Continue reading
Coding Packets the 11ty Edition
The story of how and why I migrated codingpackets.com to 11ty.Coding Packets the 11ty Edition
Last year I migrated codingpackets.com to a rails stack hosted on a digital ocean droplet. You can read about that here. I really love rails and was completely happy with that choice however, I am tired of managing infrastructure for what is essentially a static site. Therefore I decided...T-Systems Taps Juniper for Managed SD-WAN
