Treating Different Types of Communications Differently

A friend who read my Creating Sustainable Network Neutrality paper wrote to say, "Help me understand what is so bad about treating different types of communications differently." That's a really good question! If you want to offer vertically integrated services on special purpose networks, such as video entertainment or pager service or telephony, I do not have a problem with that, provided you don't use your market power to impede Internet applications that offer competing services... more

More on Broadband Router Insecurity and Being Proactive

Fergie replied on NANOG to my recent post on the subject of broadband routers insecurity: "I'll even go a step further, and say that if ISPs keep punting on the whole botnet issue, and continue to think of themselves as 'common carriers' in some sense -- and continue to disengage on the issue -- then you may eventually forced to address those issues at some point in the not-so-distant future..." He is right, but I have a comment I felt it was important - to me - to make. Not just on this particular vulnerability, but on the "war"... more

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

Examining Two Well-Known Attacks on VoIP

VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments. more

ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more

What If They Simply Made Communications Technology Better?

Rob Hyndman has a pointer to Mark Cuban's latest: Think the Internet Will Replace TV? Think Again. Cuban's post can be summarized as: Today's broadband networks are too slow. The insatiable appetite for on-demand rich media content will soon overwhelm them. Telco's aren't putting in upgraded networks quickly enough to meet that demand. Cuban also provides some facts and figures to back up that claim. In the comments, readers have a number of viewpoints, including the view that Mark has ignored cable, and that cable can provide the required speeds and feeds... more

Today’s Carrier Networks as Trollways?

As I keep pointing out -- there is indeed a viable alternative of a real marketplace not a fake one. Today's system is a fake because it depends on capturing the value of the application - communications - in the transport and that is no longer possible because with the Internet the value is created OUTSIDE the network. One example of the collateral damage caused by today's approach is the utter lack of simple wireless connectivity. Another is that we have redundant capital intensive bit paths whose only purpose is to contain bits within billing paths. more

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized. more

Competing With Satellite Cellular: AT&T Sees Little Threat but Niche Appeal Grows

AT&T’s CEO plays down the threat of satellite cellular, citing bandwidth and coverage limits. Yet growing interest in rural and IoT applications suggests the technology could still claim valuable niches in the wireless market. more

NANOG 95: From Faster Fibre to Route Leaks, Operators Face Old Problems with New Tools

The NANOG 95 conference spotlighted breakthroughs in fibre optics, wireless technology, routing security, and quantum computing, offering a forward-looking assessment of internet infrastructure and its vulnerabilities, as reported by APNIC's Geoff Huston. more

AWS Unveils Route 53 “Accelerated Recovery” to Bolster DNS Resilience

AWS is introducing Route 53 Accelerated Recovery to help organizations maintain DNS control during regional outages, offering a 60-minute recovery objective and sustained access to key API operations for critical updates and traffic management. more

US Senators Move to Shield Undersea Internet Cables from Global Threats

A bipartisan Senate bill seeks to strengthen U.S. oversight and global coordination to protect undersea fiber-optic cables, vital infrastructure increasingly targeted by geopolitical adversaries, natural disasters, and cyber or physical sabotage. more

The hiQ Decision Legalized Infrastructure Theft - We Need a Federal Fix

The hiQ ruling erased legal protections against commercial scraping, leaving infrastructure providers to absorb escalating costs. Without federal action defining data misappropriation, a free-rider AI economy could undermine open networks, investment, and long-term data integrity. more

Internet Evolution: Moore’s Law, Addressing Architectures, and the Future of Internet Scale

The Internet has evolved from a scarcity-driven system into one defined by abundance, reshaping infrastructure, governance, and economic models while challenging long-held assumptions about addressing, network roles, and the future of protocol design. more

Centralizing DNS Data for Security, Compliance, and Performance

Private DNS data lakes consolidate fragmented logs into a centralised platform, improving visibility, security, and compliance. They enable advanced analytics, strengthen threat detection, and help organisations optimise network performance in increasingly complex IT environments. more
