OpenFlow - The Programmable Network Revolution

Over the past few months I have made regular references to OpenFlow. This is an exciting new development that fits in very well with several of the next generation technology developments that we have discussed in some detail over the past few years -- new developments such smart cities and smart societies, the internet of things. Such networks need to operate more on a horizontal level, rather than the usual vertical connection between a computing device and the users. more

M3AAWG & i2Coalition Collaborate on Best Practices on Anti-Abuse in Hosting & Cloud Environments

I am excited to announce the recent release of the industry first Best Common Practices document for Cloud and Hosting providers for addressing abuse issues that was created by M3AAWG and the i2Coalition. M3AAWG has been collaborating with the Best Practices Working Group of the i2Coalition over the past 2 years to discuss ways to solve malicious activity within hosting and cloud ecosystems.  more

Pulling the Trump Card on Cloud and SDN

Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have been picking up the pace as of late. A high percentage of communication service providers and large data centers have either added these technologies on their roadmaps, or are already doing small-scale Proof-of-Concepts (PoC) in their testbed environments. more

In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more

Measuring IPv6 at the Network and the Customer Level

George Michaelson, APNIC's Senior Research and Development Scientist recently visited the RIPE NCC to collaborate on various research projects with his RIR colleagues. IPv6 measurements were one of the topics we looked at. Recent IPv6 statistics from the RIPE NCC show an accelerated uptake of IPv6 in Norway, both in terms of the number of allocated prefixes, and visible announcements in the routing system. more

On the Success of Malware

There's often a lot of discussion about whether a piece of malware is advanced or not. To a large extent these discussions can be categorized as academic nitpicking because, at the end of the day, the malware's sophistication only needs to be at the level for which it is required to perform -- no more, no less. Perhaps the "advanced" malware label should more precisely be reattributed as "feature rich" instead. more

Traffic Management: An Undefined Term

In Europe yet another package is discussed, and it includes issues related to what I guess one could call Network Neutrality. And, as usual, at the end of the game, texts are negotiated that does not have much meaning in reality. Negotiations on what words imply, while I as an engineer have absolutely no idea what either of the parties actually mean... more

Don’t Make the Internet Safe for Monopolies

This week I'm going to Washington to argue against regulating Internet access as if it were phone service. Twenty years ago I was there for the same reason. My concern now as it was then is that such regulation will damage the economy and reduce opportunity by stifling innovation and protecting the current dominant players from the startups which would otherwise threaten them. more

The Role of Mobile Broadband in the Overall Telecoms Market

The fixed broadband network is the infrastructure needed to meet the needs, both economic and societal, of developed markets. While some people in some developed markets have abandoned their fixed telephone connection in favour of all-mobile solutions, the majority (90% plus) still have both a fixed and a mobile connection... And so wireless broadband and FttH will develop, in a complementary and harmonious way. There are several reasons for this. more

The Recent DDoS Attacks on Banks: 7 Key Lessons

Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." 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

In Broadband, China Is Definitely the Middle Kingdom - 270M In 2015

With a goal of 270M fixed broadband lines in 2015 and near-universal service by 2020, the new "Broadband China" strategy is extraordinary. OFweek, a valuable site in Chinese, breaks the plan into three phases. The first is a full speed stage, ending in 2013, that deploys basic broadband and 3G widely. The second stage, 2014-2015, is dedicated to a further takeup and wider deployment. That will include 400,000+ LTE cell sites. more

Connecting the Next Billion. Is It Possible? (An African Perspective)

This year, the IGF Multistakeholder Advisory Group which provide assistance in the preparations for Global IGF meetings called for Intersessional work (activities that are pursued in the months between annual IGFs with the aim of helping the IGF produce more tangible outputs that can become robust resources). Previously, the IGF has used best Practice Forums and Dynamic coalitions to bring out key issues that affect the world as it relates to the Internet. This year's Intersessional activity is centred on "Policy Option for connecting the Next Billion". more

Broadband Demand-Side Management

Countries, cities and commercial organisations around the globe are facing problems associated with the rollout of fibre-to-the-home networks... We have been warning about these issues for well over a decade. The problem arises because the telecoms industry has been based on the principle 'build and they will come'. more

Indonesia’s Largest Telecom Provider Leaks Large Portions of the Global Routing Table

Earl Zmijewski from Renesys reports: Yesterday, Indosat, one of Indonesia’s largest telecommunications providers, leaked large portions of the global routing table multiple times over a two-hour period. This means that, in effect, Indosat claimed that it “owned” many of the world’s networks. Once someone makes such an assertion, typically via an honest mistake in their routing policy, the only question remaining is how much of the world ends up believing them and hence, what will be the scale of the damage they inflict? more
