In just one week, representatives of governments from all around the world will gather at the UN headquarters in New York for the 10-year Review of the World Summit on the Information Society, a.k.a. "WSIS+10". We are very pleased to see the consensus forming that the principles of multi-stakeholder cooperation and engagement should be at the core of the Information Society.

An Economic Perspective on Internet Centrality

The IETF met in November 2022 in London. Among the many sessions that were held in that meeting was a session of the Decentralised Internet Infrastructure Research Group, (DINRG). The research group's ambitions are lofty: DINRG will investigate open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery. more

Renesys Reporting Total Internet Blackout in Sudan

Senior Research Engineer, Doug Madory at Renesys reports: "A few hours ago, we observed a total Internet blackout in Sudan and, as we publish this blog, the Internet remains largely unavailable. By count of impacted networks, it is the largest national blackout since Egypt disconnected itself in January 2011. The massive outage came as the government began a violent crackdown on protests triggered by the government’s decision to end fuel subsidies." more

U.S. Now Leading Source of Attack Traffic, Followed by China and Russia

The U.S. became the top attack traffic source in the second quarter of 2010, accounting for 11% of observed attack traffic in total, reports Akamai in its State of the Internet Report released today. According to the report, China and Russia held the second and third place spots, accounting for just over 20% of observed attack traffic. Attack traffic from known mobile networks has been reported to be significantly more concentrated than overall observed attack traffic, with half of the observed mobile attacks coming from just three countries: Italy (25%), Brazil (18%) and Chile (7.5%). more

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

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

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

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

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

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
