Life Outside IPv6 (Poll)

Within every organization a chosen few are tasked with introducing IPv6 into their networks, outward facing services or applications. But who are they? We know them as Network Engineers, System Administrators and Software Developers but are they one trick ponies spending all their time in layer 3? 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 Year 2038 Computer Problem – a Repeat of Y2K?

The Year 2038 Problem relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer. Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038. At that time, systems might crash and be unable to restart when the time is changed to that date. It is like the Y2K problem caused by the widespread use of two decimal digits to store the year. While that problem was overhyped... more

Peering and Interconnection Key to a Competitive American Telecoms Market

Peering has come back in the news with the FCC mentioning it in its set of reviews of the telecommunications market in the USA, following its Network Neutrality decision. The peering and interconnect issues are going to the heart of the telecoms matter in relation to competition, innovation and the Open Network. You don't need Network Neutrality rules, if you have a well functioning, transparent, interoperable and competitive infrastructure environment. more

The Rise and Rise of Broadband in China

While there are plenty of articles continuously updating us on the incredible social and economic developments that are taking place in China it is still sometimes good to stand still and have a look at some of these developments. It was 15 years ago that the Chinese Government - in its 5-year plan - stated that it wanted to connect all of its half million villages to the telecommunications network. At that point the plan simply called for narrowband telephone connections. 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

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

The Role of FttH in the Development of 5G

As the roll out of FttH remains a slow process, it is no wonder that more and more people are looking towards mobile as a potential alternative. Obviously, mobile communication has improved over recent years in providing excellent access to broadband; and it has also become more affordable. At the same time, there is the fabulous hype about 5G, and the PR and media machines of the vendors involved make you believe that this will become a real competitor to the slow moving FttH developments. more

The Impacts of Hurricanes Harvey, Irma, and Maria on the Internet

The devastation caused by several storms during the 2017 Atlantic hurricane season has destroyed neighborhoods and taken lives across a number of Caribbean island nations including Texas and Florida in the United States. Senior Director of Internet Research & Analysis at Oracle Dyn Global Business Unit has posted a blog that takes a look at the impacts. 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

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

IPv6 Enabled Networks Before and After World IPv6 Day

In our last post on CircleID, Measuring World IPv6 Day - First Impressions, we showed exactly when World IPv6 Day participants switched on IPv6 on their networks (by way of announcing DNS AAAA records). Now, a few weeks after World IPv6 Day, it's interesting to see what the longer-term effects have been. 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

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

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
