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.
In their annual hype cycle on on network technologies, Gartner lists the emerging technologies and an estimate of the timeframe in which they will reach the plateau of productivity. The latest hype cycle on enterprise networking labels Software-Defined Networks (SDN) as an obsolete technology. So on the surface, it would appear that SDN is now semi-officially dead. While most natural scientists accept the Darwinian theories, the technology industry has traditionally been trying to defy evolution.
Tonight (27 Sep 2019) you can watch the 2019 Internet Hall of Fame induction ceremony streaming live out of Costa Rica. Eleven individuals from six countries will be inducted into the Internet Hall of Fame (IHOF) today. The 2019 class of inductees have expanded the Internet's reach into new regions and communities, helped foster a greater understanding of the way the Internet works, and enhanced security to increase user trust in the network.
Over at the ECI blog, Jonathan Homa has a nice article about the importance of network planning: In the classic movie, The Graduate (1967), the protagonist is advised on career choices, "In one word – plastics." If you were asked by a young person today, graduating with an engineering or similar degree about a career choice in telecommunications, would you think of responding, "network planning"? Well, probably not...
Today's Internet is a critical infrastructural element whose continued development influences industries, cultures, and the private space of most individuals. However, the world-encompassing network sometimes needs to be adapted to new requirements to keep pace with current innovations. We have recently seen accelerating development of Internet usage on the user side. Whether it is online shopping's expansion or the greater distribution of mobile devices or streaming services...
Does threat intelligence (TI) work? I looked into that question last year, exploring the reasons why it actually doesn't and what can be done to remediate the situation. Since then, more companies have incorporated TI into their security processes, and many are still not getting the benefits they expect. What's causing the dissatisfaction? Interestingly, pretty much the same aspects...
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.
With the upcoming celebration of the 50 years of the Internet, I'm trying to figure out how the traditional story misses the powerful idea that has made the Internet what it is -- the ability to focus on solutions without having to think about the network or providers. It's not the web -- thought that is one way to use the opportunity. The danger in a web-centric view is that it leads one to make the Internet better for the web while closing the frontier of innovation.
We got used to it: if we open a website, it's always like stop and go on a high-traffic highway or city traffic jam. At some point, we will reach the destination. The constant stalling is due to a traffic rule for the Internet called TCP (Transmission Control Protocol). The TCP/IP protocol family comes from the American defense industry. It was introduced by DARPA (Defence Advanced Research Projects Agency) in the early 1970s. At that time, no one had the Internet as the need of the masses on the screen.
In June, I participated in a workshop, organized by the Internet Architecture Board, on the topic of protocol design and effect, looking at the differences between initial design expectations and deployment realities. These are my impressions of the discussions that took place at this workshop. ... In this first part of my report, I'll report on the case studies of two protocol efforts and their expectations and deployment experience.
