Last week, Sandvine provided some facts and figures on the impact the closing of popular storage and back-up service Megaupload had on networks across the globe.

With the media and legal spotlight being shined on this traffic category in recent days, a number of competing sites have either decided to shut themselves down, or dramatically alter the way files are uploaded or downloaded from their servers.

One such service to make such a drastic change was FileSonic, who has halted any new uploads, and is only allowing users to download their personal files. Read the rest of this entry »

Yesterday, at roughly 2pm EST, the U.S. Justice Department shut down Megaupload, the popular Storage and Back-Up Service which accounts for roughly 1% of total traffic on fixed access networks in North America.  Also involved in the shutdown were Megaupload’s affiliate sites, which included MegaVideo, MegaPix, MegaLive, and MegaBox.

In a controversial, incredibly strange, yet kind of catchy video released last year, Megaupload claimed to have 1 billion users, accounting for 4% of Internet traffic.

Our Global Internet Phenomena Report, which has followed the growth of the service in recent years, confirms that Megaupload was the most popular Storage and Back-Up Service in almost every region. Read the rest of this entry »

=There is considerable confusion in the consumer network access industry regarding the objective of congestion relief (traffic management) and that of market-segmentation and value-definition (usage management). In particular, many players often try to message that they are addressing congestion using volume limits, when in fact this is less effective.

I’ll refer to congestion occurring closest to the subscriber as the “weak link”.  Not surprisingly, the most effective (in terms of relieving the congestion) and most fair (to subscribers) way to manage this congestion is by implementing corrective policies that are localized at the site of the congestion itself. In fact, this precise approach is what the FCC defines as “narrowly tailored”.  Referring to Figure 1 below, if congestion occurs at the weak link (see A*) location and affects only users 1-5, then correcting that instance of congestion is ideal because Internet user traffic in other network locations such as locations B and C need not be touched.

Sandvine manages link congestion by examining, identifying, and prioritizing time-sensitive gaming, VoIP and streaming applications, over non time-sensitive applications such as emailing and browsing, or, alternatively, prioritising the users who are causing the least congestion vs. those who are causing the most in a short time interval.  You and I don’t notice if we get an email 2 or 3 seconds later, but we will be upset if our voice calls are garbled and we can’t understand each other.  Read the rest of this entry »

Twice a year, Sandvine publishes our Global Internet Phenomena Report, which provides network operators, as well as subscribers, an in-depth analysis of what is happening on both fixed and mobile networks across the globe.

The research we conduct for the study gives a great snapshot of what is currently happening on broadband networks, but we thought it might be fun to take some of that insight and mix it with what we have been hearing from network operators, to make some predictions for 2012.

So without further ado, here are Sandvine’s five broad(band) projections for 2012:
