There was a somewhat unfortunate outage for a major communications service provider in Australia, Optus, in mid-November. It appears that one of their peer Border Gateway Protocol (BGP) networks mistakenly advertised a very large route collection to the Optus BGP network, which caused the routers to malfunction in some manner. more
Trust is such a difficult concept in any context, and certainly, computer networks are no exception. How can you be assured that your network infrastructure is running on authentic platforms, both hardware and software and its operation has not been compromised in any way? more
In a significant move to advance IPv6 adoption, China's Ministry of Industry and Information Technology has directed local router manufacturers to default to the IPv6 protocol from December 1, 2023 onwards. more
A few years ago, there were a lot of predictions that we'd see broadband networks converting to quantum technology because of the enhanced security. As happens with many new technologies, quantum computing is advancing at a slower pace than the wild predictions that accompanied the launch of the new technology. more
The Uptime Institute (UI) is an IT industry research firm best known for certifying that data centers meet industry standards. UI issues an annual report that analyzes the cause of data center outages. The causes for data center outages are relevant to the broadband industry because the same kinds of issues shut down switching hubs and Network Operations Centers. more
ome 50 years ago, at the Palo Alto Research Centre of that renowned photocopier company Xerox, a revolutionary approach to local digital networks was born. On the 22nd of May 1973, Bob Metcalf authored a memo that described "X-Wire," a 3Mbps common bus office network system developed at Xerox's Palo Alto Research Center (PARC). more
The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17th century to explain how light could be transmitted through a vacuum. more
At Verisign, we believe that continuous improvements to the safety and security of the global routing system are critical for the reliability of the internet. As such, we've recently embarked on a path to implement Resource Public Key Infrastructure (RPKI) within our technology ecosystem as a step toward building a more secure routing system. In this blog, we share our ongoing journey toward RPKI adoption and the lessons we've learned as an operator of critical internet infrastructure. more
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 little appreciated aspect of our digital infrastructure is just how dependent we are on access to time. Disrupting the time base can not only lead to disruption in communications but can result in various forms of compromise of the integrity of communications. Accurate time was all but unobtainable for centuries, and then, as we spent significant sums devising even more accurate timekeeping instruments, accurate time became a specialized service. more
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
In a recent workshop, I attended, reflecting on the evolution of the Internet over the past 40 years, one of the takeaways for me is how we've managed to surprise ourselves in both the unanticipated successes we've encountered and in the instances of failure when technology has stubbornly resisted to be deployed despite our confident expectations to the contrary! What have we learned from these lessons about our inability to predict technology outcomes? more
In a recent blog post, Amazon invited developers to test drive its gigantic IoT network. This network has been labeled 'Sidewalk' and was created by tying together all of Amazon's wireless devices like Amazon Echos and Ring cameras. Amazon claims this huge wireless network now covers 90% of U.S. households. Amazon created the network by transmitting Bluetooth and 900 MHz LoRa signals from its various devices. more
Microsoft continues to integrate new artificial intelligence technology into its products and today announced a cybersecurity "copilot" to help companies track and defend against hacking attempts. This tool is part of Microsoft's attempt to dominate the fast-growing field of "generative" AI. more
A recent report by NS1 provides a comprehensive look at global DNS traffic trends. It reveals that public resolvers dominate the internet, accounting for nearly 60% of recursive DNS usage. Telecom giants represent nearly 9%, with Google the clear front-runner at a little over 30%, followed by Amazon Web Services at 16%. more
