Network Complexity: Three Trends That are Contributing to a “Perfect Storm”

Most everyone who visits CircleID is familiar with Moore's Law, which stated simply holds that computing power doubles every 18 months. This has been going on since the 1960s and shows no sign of slowing. Moore's Law drives faster and faster computing, which produces more and more data and network complexity. This inexorable trend is putting immense pressure on corporate networks, and the strain is too much for many of them to handle on their own. more

First Square Mile is not the Last or First Mile: Discovery not Just Choices!

The term "last mile" highlights the fact that we are the consumers at the end of a broadband "pipe". Saying "first mile" is a little better but the Internet is not a pipe to or from somewhere else. It's about what we can do locally and then what we can do when we interconnect with other neighborhoods. It's better to describe our neighborhood as the first square mile. Telecom is about selling us services; the Internet is about what we can do ourselves locally and then interconnecting with others everywhere. In writing the First Square Mile - Our Neighborhood essay which I just posted I came to better understand the fundamental difference between the world of telecom which is about giving you choices and the Internet which provides opportunity to discover what we can't anticipate... more

Is LTE Going to Impact Free WiFi?

Developments in LTE are also going to have a significant impact on the unlicensed spectrum, which is currently used by billions of people through their WiFi modems and WiFi services in cities, cafes, airports and other venues. Known as LTE Unlicensed (LTE-U) or Licensed-Assisted Access (LAA), this technology can also ride on top of WiFi networks (without utilising the mobile service), providing high-speed broadband access to users. more

United States Is the Most Bot-Infected Country. Right?

A couple of days ago, Threatpost posted an article indicating that the United States is the most bot-infected country... I think that Microsoft's mechanism of measuring bot infections is a good one, not necessarily because it is the most accurate but because it represents the most complete snapshot of botnet statistics. Because Microsoft Windows is installed on so many computers worldwide and because so many users across the world call home to the MSRT, Microsoft is able to collect a very large snapshot of data. more

Innovation Today is IN the Network

The largest and most important global information infrastructure today by any measure is clearly the global mobile network and all of its gateways, services, and connected devices. That network is standardized, managed, and energized by a combination of the 3GPP and GSMA. The level of 3GPP industry involvement and collaboration today probably exceeds all other telecom, internet, and assorted other bodies put together... and then some. more

Securing the Core

BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more

New Report About Internet Routing With MANRS

I find myself reading, frequently, about "interesting" exploits of IP routing. Recent history includes the redirection of Telegram traffic to Iran, Google traffic to China, and Cloudflare traffic to Nigeria -- and, per bgpstream.com, 64 events this month, 18 of them on one day. Is this expensive? You bet, both in money and in mindshare. Imagine the impact of discovering your company's name in the press. more

Cuba Getting Faster YouTube Access in Next 24 Hours, Thanks to Deal Signed in December

In the December of last, Cuba singed a deal with Google to enable faster access to content served via its popular platforms such Gmail and YouTube. more

Protecting an Enterprise from Cyber Catastrophe

We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more

Why CDNs Are Critical to Future of R&E Networks, Big Data and the Internet

Netflix has announced that they are deploying their own Content Delivery Network (CDN) for delivery of their video streams to Internet Exchange Points (IXPs) around the world. More importantly they are making the hardware and software design of their CDN servers freely available. That means any network can deploy Netflix CDN boxes deep into their network to significantly reduce traffic volumes and improve performance for users. more

Privacy and Security - Five Objectives

It has been a very busy period in the domain of computer security. With "shellshock", "heartbleed" and NTP monlink adding to the background of open DNS resolvers, port 445 viral nasties, SYN attacks and other forms of vulnerability exploits, it's getting very hard to see the forest for the trees. We are spending large amounts of resources in reacting to various vulnerabilities and attempting to mitigate individual network attacks, but are we making overall progress? What activities would constitute "progress" anyway? more

Going Dark: How the Increasingly Dark Network Is Creating Some Pretty Ugly Choices for Site Security Administrators

I'd like to reflect on a presentation by Dr. Paul Vixie at the October 2022 meeting of the North American Network Operators Group (NANOG) on the topic of the shift to pervasive encryption of application transactions on the Internet today. There is a view out there that any useful public communications medium needs to safeguard the privacy and integrity of the communications that it carries.  more

Netflix Has Buyer’s Remorse Over Its Paid Peering Deal With Comcast

Soon after capitulating to Comcast's surcharge demand for improved treatment of its traffic, Netflix got better downstream delivery speeds. Apparently Comcast did not have to undertake a major bandwidth expansion program. Much to the immediate relief of Netflix, Comcast merely needed to allocate more ports for Netflix traffic. So with a reallocation of available bandwidth, Comcast solved Netflix's quality of service dilemma apparently without degrading service to anyone else, upstream or downstream. more

IPv6 Security Considerations

When rolling out a new protocol such as IPv6, it is useful to consider the changes to security posture, particularly the network's attack surface. While protocol security discussions are widely available, there is often not "one place" where you can go to get information about potential attacks, references to research about those attacks, potential counters, and operational challenges. more

US Federal Judge Dismisses Kaspersky Lawsuit, Government-Wide Ban Stays in Place

The two lawsuits filed by the Russian software firm Kaspersky Lab against the U.S. government banning federal networks from using the company's anti-virus software was dismissed on Wednesday by a federal judge. more
