Gall’s Law and the Network

In Systemantics: How Systems Really Work and How They Fail, John Gall says: "A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system." In the software development world, this is called Gall's Law... more

Interstate at Rush Hour ...in the Rain ...on a Friday – AKA, Your Enterprise Traffic on the Net

Congestion. Traffic. Two words that draw a visceral response, whether you are commuting to work or managing a network. Managing data traffic used to be easy. Everything was housed in centralized data centers, and all traffic was routed through big, dedicated, effective but expensive "pipes" -- Multiprotocol Label Switching (MPLS) links. When all the applications are at the data center, it makes sense to build private access for all traffic. more

Jevons Paradox and Internet Centrality

The story of computing and communications over the past eighty years has been a story of quite astounding improvements in the capability, cost and efficiency of computers and communications. If the same efficiency improvements had been made in the automobile industry cars would cost a couple of dollars, would cost fractions of a cent to use for trips, and be capable of travelling at speeds probably approaching the speed of light! more

Reframing the Infrastructure Debate

Fast and reliable infrastructure of any kind is good for business. That it's debatable for the Internet shows we still don't understand what the Internet i -- or how, compared to what it costs to build and maintain other forms of infrastructure, it's damned cheap, with economic and social leverage in the extreme. Here's a thought exercise... Imagine no Internet: no data on phones, no ethernet or wi-fi connections at home - or anywhere. No email, no Google, no Facebook, no Amazon, no Skype. That's what we would have if designing the Internet had been left up to phone and cable companies... more

Happy Birthday, Backbone

Today marks the 20th anniversary of the decommissioning of the NSFNET backbone on April 30 1995, an important milestone in the development of the commercial Internet. The NSFNET was set up by the US National Science Foundation in 1985 to enable university researchers access to five supercomputer sites across the United States, using Internet Protocol technology. In stepping back, the NSF supported a transition to an Internet shaped by market forces, and the explosion of commercial use soon followed. more

Give Network Administrators a Zero-Impact Firmware Update Solution

Struggles with the firmware update process are well known by Network Administrators in the cable industry. The copious tasks required to complete an end-to-end firmware update are painstaking and error-prone, often making the investment not worth the time it takes to complete the work... imagine doing these manual tasks over and over for hundreds to thousands of devices, many from different vendors, each with its own unique device update path! Clearly, this complex challenge needs a solution. more

Predictions for a Post-COVID-19 World

While it might still be too early to make predictions, there are dozens of articles on the web predicting how the COVID-19 pandemic might change our long-term behavior. Here are some of the more interesting predictions I've seen that involve broadband and telecom... Millions of people were sent home for work or school to homes that didn't have good broadband. These folks have been telling the world for years that they don't have good broadband... more

Russian Central Bank Announces Mandatory Cyber-Security Regulations for Domestic Banks

"Russian banks will be faced with a whole range of new regulations, and penalties for non-compliance, when it comes to cyber-security, according to the country's Central Bank," Eugene Gerden reported today in SC Magazine UK more

RIPE 86 Bites: Gigabits for EU

Rudolph van der Berg presented on the latest updates from the ongoing tensions in the Internet industry between carriage infrastructure providers and content providers, with a European perspective. The carriage providers in the EU region are asserting that they're making major capital investments in augmenting the access network infrastructure to carry gigabit traffic volumes, which is largely streaming content, while at the same time the content providers were getting a free ride, or so goes the argument. more

MANRS Observatory: Monitoring the State of Internet Routing Security

Routing security is vital to the future and stability of the Internet, but it's under constant threat. Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, driven by the networking community and supported by the Internet Society, aiming to reduce the most common threats to the Internet's routing system through technical and collaborative action. more

Major International Botnet Disabled Says U.S. Department of Justice

The U.S. Department of Justice and the FBI announced on Wednesday that they have taken actions to disable an international botnet of more than two million infected computers responsible for stealing corporate data including user names, passwords and financial information. more

China Nearing Full Mobile Broadband Coverage

China’s mission to put its entire population on the internet is almost complete, as analysts predict full mobile broadband network coverage in the world’s second-largest economy within the next few years. more

Canadian Energy Firms at Bigger Risk of Cyberattack

The Canadian Security Intelligence Service (CSIS) is reported to have warned companies about an increasing risk of cyber espionage and attacks on pipelines, oil storage and shipment facilities. more

RIPE 86 Bites: Encryption and Active Network Management

Change is hard, and the larger the system, the slower the pace of change. There are just so many systems that need to change their behaviors, and the motivations of users, vendors, service providers, content generators and many others all vary. Getting all of us to change some aspect of our technology, platform or application set is hard, if not impossible, to orchestrate such that it happens at the same time. more

A New Busy Hour – One of the Many Consequences of the COVID-19 Pandemic

One of the many consequences of the coronavirus is that networks are going to see a shift in busy hour traffic. Busy hour traffic is just what it sounds like -- it's the time of the day when a network is busiest, and network engineers design networks to accommodate the expected peak amount of bandwidth usage. Verizon reported on March 18 that in the week since people started moving to work from home that they've seen a 20% overall increase in broadband traffic. more
