Why Don’t We Have Peak and Off-Peak Pricing for Broadband?

I saw a poster on the London Underground yesterday, and as is often the case it got me thinking about the parallels with telecoms. The poster explains the peak and off-peak fare structure for tube travel. The purpose of this pricing system is to manage the relationship between supply and demand in a system that is capacity constrained. Over short and medium timescales the supply is essentially fixed, and demand can oversaturate that supply. more

Researches Demonstrate How IPv6 Attacks Can Bypass Network Intrusion Detection Systems

With the increasing popularity of IoT devices and the added interest of transition to IPv6, a whole new range of threat vectors are evolving that allow attackers to set up undetectable communications channels across networks. more

Dissecting the (Likely) Forthcoming Repeal of the FCC’s Privacy Rulemaking

Last week, the House and Senate both passed a joint resolution that prevent's the new privacy rules from the Federal Communications Commission (FCC) from taking effect; the rules were released by the FCC last November, and would have bound Internet Service Providers (ISPs) in the United States to a set of practices concerning the collection and sharing of data about consumers. The rules were widely heralded by consumer advocates, and several researchers in the computer science community, including myself, played a role in helping to shape aspects of the rules. more

Flipping the Kill Switch: Internet Restrictions Becoming the New Normal

The Internet was built on the promise that everyone, everywhere could create, share information and ideas without frontiers. Yet, Internet restrictions are increasing to the point they are becoming the norm. And it's happening fast. In its 2016 Freedom on the Net report, Freedom House revealed that Internet freedom declined for the 6th year in a row. The report notes that more governments have been blocking social media and communication apps than ever before. more

Networks - The Next Challenge in Digital Transformation

As digital transformation has been picking up momentum, leading analysts such as 451 Research have suggested that hybrid multi-clouds and automated DevOps will become key constituents powering enterprises in the new era. At the heart of these enabling technologies lies Lifecycle Service Orchestration (LSO) designed for near-autonomous application deployment across hybrid infrastructures consisting of traditional on-premise data centers and public clouds. more

Shedding Light on How Much Energy the Internet and ICTs Consume

Ever since I published an essay exploring the relationship between climate change and the Internet, I have endeavored to bring this subject to the fore as often as possible (and in relevant fora and discussions) since the responsibility of creating a more sustainable world falls on all communities and stakeholder groups. It is particularly pressing now -- at a time when international interest in curbing climate change is strengthening, while it is juxtaposed with the receding commitments of the United States government... more

Network Dis-Aggregation and SDN: Different, But Related

Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more

Google Claims It Fixed the Security Holes the CIA Exploited

WikiLeaks shook the internet again on March 7, 2017, by posting several thousand documents containing information about the tools the CIA allegedly used to hack, among others, Android and iOS devices. These classified files were obtained from the CIA's Center for Cyber Intelligence, although they haven't yet been verified and a CIA official declined to comment on this incident. This isn't the first time that the U.S. government agencies were accused of crossing the line and undermining online security and civil liberties, as it's been only a year since the infamous FBI-Apple encryption dispute. It's like "1984" all over again. 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
