Let American Telcos and Cablecos Merge - But Declare Infrastructure a Utility

While there is much discussion in the United States about the mergers of Comcast and Time Warner Cable, and of AT&T and DirectTV, issues such as this are generally discussed from a very narrow perspective and, we maintain, from the wrong underlying telecoms regime operating in that country - one that has stifled competition in the telecoms for nearly two decades. The same wrong parameters apply to the endless debates on net neutrality an issue that is, by the way, largely of significance to the US market alone. more

Intelligence Exchange in a Free Market Economy

The U.S. Government is causing a huge disservice to protection and defense in the private sector (80%+ of CIKR) by creating an ECS that contains monetary incentive for a few large players to exert undue control over the availability, distribution, and cost of security threat indicators. While there may be a legitimate need for the federal government to share classified indicators to entities for protecting critical infrastructure, the over-classification of indicator data is a widely recognized issue that presents real problems for the private sector. ECS as currently construed creates monetary incentives for continued or even expanded over-classification. more

Notes from NANOG 69

NANOG 69 was held in Washington DC in early February. Here are my notes from the meeting. It would not be Washington without a keynote opening talk about the broader political landscape, and NANOG certainly ticked this box with a talk on international politics and cyberspace. I did learn a new term, "kinetic warfare," though I'm not sure if I will ever have an opportunity to use it again! more

U.S. Complaint to WTO on China VPNs Is Itself Troubling

On 23 February, the U.S. Administration had the chutzpah to file a formal communication to the World Trade Organization (WTO) complaining about "measures adopted and under development by China relating to its cybersecurity law." However, it is the U.S. complaint that is most troubling. Here is why. The gist of the U.S. complaint is that China's newly promulgated directive on the use of VPN (Virtual Private Network) encrypted circuits from foreign nations runs afoul of... more

Cable & Wireless US$3B Deal to Acquire Columbus Exposes Vulnerabilities in Caribbean Telecom Sector

When Cable & Wireless Communications (CWC) announced an agreement to acquire Columbus International, news of the deal sparked widespread concerns about the impact of reduced competition on consumer pricing, infrastructure investment and wider economic development in the Caribbean. If approved, the deal will make CWC the Caribbean's largest wholesale and retail broadband service provider. At the same time, it will return several Caribbean territories into monopoly or near-monopoly markets... more

Unintended Consequences of Submarine Cable Deployment on Internet Routing

The network layer of the Internet routes packets regardless of the underlying communication media (Wifi, cellular telephony, satellites, or optical fiber). The underlying physical infrastructure of the Internet includes a mesh of submarine cables, generally shared by network operators who purchase capacity from the cable owners. As of late 2020, over 400 submarine cables interconnect continents worldwide and constitute the oceanic backbone of the Internet. more

Our New Infrastructure

Today, there is demand for more broadband as people realize the importance of being connected to the Internet, whether to access websites, stream entertainment, attend school, attend family events, work remotely, and so much more. This demand has been driven by the success of today's Internet. It is now time to recognize the Internet as infrastructure. The Internet's best-effort approach has allowed us to share the abundant capacity latent in the existing facilities by converting all traffic into packets. more

Fifty Years On – What to Expect in the Next 50 Years of the Internet

When did the Internet begin? It all gets a bit hazy after so many years, but by the early 1970s, research work in packet-switched networks was well underway, and while it wasn't running TCP at the time (the flag day when the ARPANET switched over to use TCP was not until 1 January 1983) but there was the base datagram internet protocol running in the early research ARPA network in the US. Given that this is now around 50 years ago, and given that so much has happened in the last 50 years, what does the next 50 years have in store? more

The Test of Time at Internet Scale: Verisign’s Danny McPherson Recognized with ACM SIGCOMM Award

The global internet, from the perspective of its billions of users, has often been envisioned as a cloud -- a shapeless structure that connects users to applications and to one another, with the internal details left up to the infrastructure operators inside. From the perspective of the infrastructure operators, however, the global internet is a network of networks. It's a complex set of connections among network operators, application platforms, content providers and other parties. more

Name Collisions, Why Every Enterprise Should Care (Part 3 of 5)

Do you recall when you were a kid and you experienced for the first time an unnatural event where some other kid "stole" your name and their parents were now calling their child by your name, causing much confusion for all on the playground? And how this all made things even more complicated - or at least unnecessarily complex when you and that kid shared a classroom and teacher, or street, or coach and team, and just perhaps that kid even had the same surname as you, amplifying the issue! What you were experiencing was a naming collision (in meatspace). more

Fine Grained Mail Filtering With IPv6

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more

Guadeloupe Moves to Set Up Internet Exchange Point

Developments in the Caribbean digital space are fuelling initiatives to strengthen the Internet infrastructure in the region. In Guadeloupe, a recent agreement among three Internet service providers has cleared the way for the island to establish its first Internet exchange point. Commonly called an IX or an IXP, an Internet exchange point is a critical element of Internet infrastructure used to interconnect networks and deliver data traffic between them. more

IPv6: The Summer It Finally Happened

A decade old guessing game finally came to an end during these 2012 summer months. America was supposed to be hopelessly behind while Europe had not much to show after a decade of spending lavishly EU money on IPv6 related projects. China and Japan were thought to be light years ahead of everybody else. But in the end, it was the might of the American Content Industry that tipped the scales. more

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more

Why Telcos Don’t Get Networks

I've posted to SSRN my paper on why most telecom companies, even though they operate networks, don't appreciate the fundamental business dynamics of network structures. This will be a chapter in a book Wharton is publishing on network-based strategies and competencies. In the paper, I describe two views on telecom and Internet infrastructure... more
