Internet Engineering Task Force (IETF) has announced the official release of TLS 1.3. more
There are many network operator group meetings being held these days. Even in the backwater of the South Pacific where I live there is now AUSNOG, and NZNOG is just next door in New Zealand. We now have MENOG in the Middle East and AFNOG in Africa. The original NOG was the North American Network Operators Group (NANOG), and they have the T-Shirts to prove it! NANOG meets three times a year, and I attended NANOG 41 in October 2007. NANOG meetings cover a broad variety of topics, from operational tools, measurement, and peering practices through to a commentary on the state of the Internet industry. Here are my impressions of the meeting. more
The recent launch of Google Wave generated a lot of attention, and for good reason. It's recently crossed my path in a few different settings, and while the news is still fresh, there is a lot here for service providers to be thinking about. At a high level, Wave is Google's entry into the real time collaboration space, and being Web-based, is poised to disrupt the status quo, not just for vendors, but service providers as well. more
World IPv6 Launch kicked off 6 June 2012 at 00:00 UTC. On this day, multitudes of website operators, network operators and home router vendors from all over the world have joined thousands of companies and millions of websites in permanently enabling the next generation Internet. They have done this by turning IPv6 support on by default in (at least some of) their products and services. This is a major milestone in the history of the Internet. more
Kevin Shatzkamer, Chief Architect for Cisco Mobility, speaks to the mobile research Cisco has developed in helping Mobile Service Providers reach their ROI goals and objectives in projecting an increasingly demand driven market. ... There has been speculation for years that increased demand for mobile video would tax and possibly crash current networks and infrastructures of mobile operators. A predictor may be The World Cup games held in South Africa. more
At the Internet Engineering Task Force (IETF) it is time we accept the wide range of drivers behind (and implications of) standards and for stakeholders to start listening to each other. A protocol recently released by the IETF, DNS over HTTPS (DoH), is at the centre of an increasingly polarised debate. This is because DoH uses encryption in the name of security and privacy and re-locates DNS resolution to the application layer of the Internet. more
40 years ago the Request for Comments (RFC) process for the Internet was born. The RFC process continues to be the way Internet protocols are expressed today. We have one very special man to thank for this and his name is Dr. Stephen D. Crocker. He has played a key role in shaping the modern day Internet. For this, I felt that a special tribute to him was in order as we take a look at his countless contributions from the foundation of the Internet to the Internet as we know it today. more
The debate around encryption has become a hot topic in a world where communications are increasingly becoming digital. The modern encryption debate is a complex and nuanced issue, with many players from different backgrounds trying to influence the conversation. The question of balancing the need for national security with the right to privacy has been a matter of public debate for years. Only recently has the issue been framed in terms of encryption, but the discussion is certainly not new. more
Significant changes to the core Internet protocols are underway due to the increased necessity to overcome limits that have become apparent particularly with regards to performance. more
Why are networks so insecure? One reason is we don't take network security seriously. We just don't think of the network as a serious target of attack. Or we think of security as a problem "over there," something that exists in the application realm, that needs to be solved by application developers. Or we think the consequences of a network security breach as "well, they can DDoS us, and then we can figure out how to move load around, so if we build with resilience (enough redundancy)... more
After more than two years of work behind closed doors, the Global Network Initiative is launching this week. That's the corporate code of conduct on free speech and privacy I've been talking about in generalities for quite some time. By midnight Tuesday U.S. East Coast time, the full set of documents and list of initial signatories will be made publicly available at globalnetworkinitiative.org. more
Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography... It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. more
The National Institute for Standards and Technology (NIST) has released a second draft of a proposed standards profile to support the implementation of IPv6 by government agencies. "NIST developed the 'profile' to help ensure that IPv6-enabled federal information systems are interoperable, secure and able to co-exist with the current IPv4 systems." ...The White House's Office of Management and Budget declared in 2005 that all federal agencies shall migrated to IPv6 by June 30, 2008... more
On September 30, 2002, the Memorandum of Understanding (MOU) between the US Department of Commerce (DOC) and the corporation created to privatize the infrastructure of the Internet will expire. This corporation, known as ICANN (Internet Corporation for Assigned Names and Numbers) has had a very contentious existence from its earliest days. On July 10, 2002, a US Department of Commerce official, Nancy Victory, sent a letter to ICANN. She wrote that the agreement between ICANN and the DOC "will expire on September 30, 2002 and in the coming weeks, the Department of Commerce will assess whether to renew, extend, or modify this agreement. To assist in this review process," Victory asked, "I request that you provide me with a report detailing ICANN's efforts in these areas, as well as any other information that might inform the Department in its decision-making with respect to this agreement." Victory said that the response to her letter should be sent no later than August 15, 2002. more
A dialogue between Michael Warner (Historian, United States Cyber Command) and Tony Rutkowski (Cybersecurity engineer, lawyer and historian). Michael is chairing a cyber history panel at the October biennial Symposium on Cryptologic History hosted by the National Security Agency; his panel will include discussion of the almost unknown key role of cryptologist Ruth Nelson leading a team in the 1980s in a major initiative to secure public internet infrastructure. more
