IPv6… The Dangers of Prolonged Inter AS Tunnel Vision

Tunnel vision is a rather serious medical condition and the Internet or at least a number of service providers could be at risk if not treated soon enough. Symptoms of inter AS (Autonomous System) tunnel vision are many slower connections with IPv6 compared to IPv4 with some failing all together. Reason is that tunnels, especially inter-AS tunnels, can lead to long paths and non-optimal routing. more

21 Experts Give Their 2014 Predictions on Internet Performance

Last week, we started an email thread (old school!) amongst a large group of our tech leadership and thought leaders from all aspects of web traffic management and message management. There was a simple question we wanted to know in a few sentences or less: "In 2014, what do you think the big trends will be with Internet performance?" What follows are 21 very unique, and some very similar, answers. Without a doubt, there are challenges ahead for the Internet as we know it, but the rewards for accomplishing goals are massive. more

Mobiles Moving Into Fixed Networks

There are often confused reports in the media about mobile and fixed broadband, with arguments that one could replace the other. Yet the reality is that they coexist and complement each other - perhaps even more so since one cannot manage without the other. Increasingly, devices such as smartphones, tablets and smart TVs are at the end of fixed lines, with a wireless (WiFi) connection between the fixed line and the device. more

Microsoft Becomes the Latest Company to Join the Internet Society’s MANRS Initiative

Microsoft has joined the Mutually Agreed Norms for Routing Security (MANRS) initiative, supported by the Internet Society (ISOC) with the primary objective is to reduce the most common threats to the Internet's routing system. Microsft is the latest of a number of industry giants around the world - including Oracle, GÉANT, and Comcast - to join MANRS. more

What Must We Trust?

My Twitter feed has exploded with the release of the Kaspersky report on the "Equation Group", an entity behind a very advanced family of malware. (Naturally, everyone is blaming the NSA. I don't know who wrote that code, so I'll just say it was beings from the Andromeda galaxy.) The Equation Group has used a variety of advanced techniques, including injecting malware into disk drive firmware, planting attack code on "photo" CDs sent to conference attendees, encrypting payloads... more

DNS Oblivion

Technical development often comes in short, intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn't all that secure, and it wasn't totally reliable, but it worked well enough for the purposes we put it to. more

Jugaad Innovation and Applications of DNSSEC

It would be one of the ironies of global technology development that the West has effectively so far followed a Jugaad principle of "good enough" innovation for DNS security, whereas India could well embrace all the latest advances in DNS security as its Internet economy grows. Like most other protocols from the early Internet, the DNS protocol was not designed with security built in. For those protocols, security services were typically either implemented at a different layer of the protocol stack, or were added on later. more

Questions About the Robustness of Mobile Networks

With mobile phones having become a utility, people are beginning to rely completely on mobile services for a large range of communications. All mobile users, however, are aware of some level of unreliability in these phone systems. Blackspots remain all around the country, not just outside the cities, and in busy areas the quality of the service goes down rather quickly. Drop-outs are another fairly common occurrence of mobile services. more

Reflections on NANOG 66

The North American Network Operators Group (NANOG) continues to be one of the major gatherings on network operators and admins, together with the folk who work to meet the various needs of this community. Their program committee produces a program that never fails to provide thought provoking interest. Here are my reactions to some of the presentations I heard at NANOG 66, held in San Diego in February. more

The End of Broadband Networks as We Know Them

A group of major telecommunications companies -- Vodafone, BT, Telefonica and Deutsche Telekom -- recently announced something a bit unexpected. In the Open BNG Operator Position Paper, they call for a fundamental, industry-wide change to the way broadband networks are built. Specifically, they advocate for collaboration throughout the telco world, with a convergence around open broadband network gateways (BNGs). more

The East Asia Telecommunication Union

That's what Europeans are now calling the venerable old International Telecommunication Union -- EATU for short. In fact, based on current metrics, this transformation is exactly what has occurred. The shift began occurring almost a decade ago, and has dramatically accelerated in recent years. At the ITU-T's key Study Group 17 meeting on security now underway, fully 90% of the input contributions and more than half of those participating are from only three countries -- China, Japan, and Korea. Indeed, there has long been a semi-formal organization known as CJK that has been manifested here. more

Belize to Host Caribbean Peering and Interconnection Forum

Belize will host the fourth Caribbean Peering and Interconnection Forum, known as CarPIF, on June 13 and 14. Since its inception in 2015, CarPIF has brought together regional and international technology experts and telecommunications industry execs to discuss a range of topics related to Internet peering and interconnection trends, and their relevance to the Caribbean region. more

The Hidden Value of IPv4 Addresses

All devices that connect to the internet need unique addresses. The number of IP addresses is limited, creating a demand for addresses worldwide, particularly from the cloud computing industry. This demand has raised the value of IPv4 to levels that the internet's original developers didn't predict, in part because the internet was considered an experiment at the time. Of course, use - and so demand -- has exceeded anyone's realistic expectations. 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

Cloud Services Drive Data Center Markets

Research from Infonetics shows that last year was a strong year for data centre network equipment sales, due to a rebound from bare-bones 2009 spending levels and, more importantly, fundamental trends favouring investments in the data centre, such as the explosion of content and traffic, use of virtualization, and increasingly, cloud-based services and architectures. more
