Building a Secure Global Network

Recently, the DNS has come under an extensive attack. The so-called "DNSpionage" campaigns have brought to light the myriad methods used to infiltrate networks. These attacks employed phishing, system hopping via key exfiltration, and software zero day exploits, illustrating that many secure networks may not be fully protected. more

America Closing Down Its Copper Network - So What’s Next?

We have reported in the past on the rapid decline of the copper telecoms network in the USA. A decade ago BuddeComm predicted that it would be impossible to move two customer access networks in parallel towards the new fibre future, the one operated by the telcos and the other operated by the cable companies. At that stage we indicated that a possible outcome could be that the telcos would upgrade their networks to FttH and that the cable companies would become the key tenants on that network. more

Security and Reliability: A Closer Look at Vulnerability Assessments

Building on my last article about Network Assessments, let's take a closer look at vulnerability assessments. (Because entire books have been written on conducting vulnerability assessments, this article is only a high level overview.) What is a vulnerability assessment? 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

BGP Hijacks: Two More Papers Consider the Problem

The security of the global Default Free Zone (DFZ) has been a topic of much debate and concern for the last twenty years (or more). Two recent papers have brought this issue to the surface once again - it is worth looking at what these two papers add to the mix of what is known, and what solutions might be available. The first of these traces the impact of Chinese "state actor" effects on BGP routing in recent years. more

Hyperconvergence, Disaggregation, and Cloud: The Foggy Future of Network Engineering

The world of networking tends to be bistable: we either centralize everything, or we decentralize everything. We started with mainframes, passed through Lotus 123 hidden in corners, then to mini's and middleware, then to laptops, and now to the cloud, to be followed by fog. This particular cycle of centralization/decentralization, however, has produced a series of overlapping changes that are difficult to decipher. You can somehow hear someone arguing about disaggregation and hyperconvergence through the fog -- but just barely. more

IPv6: Less Talk and More Walk

The sixth month of the year is both symbolic and historic for IPv6 and a good time to take stock and see how we've progressed. But instead of looking at the usual suspects of number of networks, number of users, number of websites, etc... on IPv6, let's look at some new trends to see what's happening. At gogo6 we've been measuring the "Buzz" of the IPv6 market every week over the last two and a half years. more

Why Most Discussions for Fibre Optic Infrastructure Take Place from the Wrong Perspective

Fibre-based infrastructure requires vision and recognition of the fact that many of today's social, economic and sustainability problems can only be solved with the assistance of information and communications technology (ICT). In many situations the capacity, robustness, security and quality necessary for this calls for fibre optic infrastructures. This need will increase dramatically over the next 5 to 10 years as industries and whole sectors (healthcare, energy, media, retail) carry out the process of transforming themselves in order to much better address the challenges ahead. more

Russian Internet Traffic Redirected Due to Routing Errors by China

Doug Madory, Director of Internet Analysis at Dyn, is reporting that the Russian Internet traffic (including domestic traffic) was re-routed out of the country due to routing errors by China Telecom. more

BYOD Woes and Worries

Like the scene of a movie in which a biblical character holds back the mighty sea and is about to release the tide against his foes, BYOD has become a force of nature poised to flood those charged with keeping corporate systems secure. Despite years of practice hardening systems and enforcing policies that restrict what can and can't be done within the corporate network, businesses are under increasing (if not insurmountable) pressure to allow a diversifying number of personal devices to connect to their networks and be used for business operations. more

Industry Structure at the Core of WCIT Problems

At the WCIT in Dubai it is interesting to follow the debates surrounding the many issues being addressed at this world congress. There are the issues of internet governance in the broadest sense of the word - these have received widespread attention. But if we look at the core issues that an organisation such as the ITU can address then the scope widens - to topics such as the rules for the International Telecommunications Regulations (ITRs), and particularly those in relation to the rules for rates and charges. more

Deadline of April 10 to Apply For CARIS Workshop on Coordinating Response to Internet Attacks

You have just a couple of days to either complete a survey or submit a paper to join the "Coordinating Attack Response at Internet Scale (CARIS)" Workshop happening on June 19, 2015, in Berlin, Germany... If you are interested in helping improve the overall security and resilience of the Internet through increased communication between the groups responding to the large-scale attacks happening on the Internet every day, I would strongly encourage you to apply! more

Some of the World’s Largest Investors Are Investing in FttH

While some governments are still struggling with the concept of FttH - some of the world's largest investors such as the Dutch superannuation funds (ABP, PGGM and Pensioenfonds Vervoer (PfV)), have been investing in FttH in the Netherlands since 2010. This is happening in a country with a broadband cable network that covers 95% of the country and nationwide access to ADSL2+ networks. more

Google and the Future of FttH

Many commentators rushed into print when they heard that Craig Barratt, senior vice-president of Google's parent company Alphabet and CEO of Access (the unit of which Google Fiber is part), stated that he would quit the job and that Google would slow down or stop its fibre deployment. So, yes, obviously something is happening at Google; but at the same time, the company has a commitment to complete the fiber deployment projects it has already started and also to build the many new networks that have been announced over the last six months. more

Why SDN is Not Enough

A hot topic in telecoms at the moment is 'software-defined networking' (SDN). This term covers a range of technologies that put networks under the control of centralised management software. But what if SDN misses the point of why broadband networks exist in the first place? Network equipment vendors are busy pushing operator CTOs to adopt a 'software telco' approach. A small army of analysts and consultants cheer this process on. more
