Lindsay Newell, VP, Marketing Networks & Platforms Group, Alcatel-Lucent, writes in a post to ALU's blog that "On November 15, Facebook released new versions of their mobile app for Android and iOS. Prior to the new release, Facebook signaling and airtime already accounted for 10% and 15% of the overall load on 2G/3G networks, respectively. As users around the world updated and started to use this new version, we quickly noticed a dramatic increase of almost 60% in the signaling load and 25% in the airtime consumed by the Facebook application. During the same period, the number of Facebook users increased by only 4%. Clearly, it is not the swelling of Facebook’s community that intensified the load, but rather the introduction of new Facebook features for mobile users and underlying platform changes .. The effect on service provider networks was significant, driving up overall (total) signaling traffic and airtime consumption by 5-10%".
"Another trend we detected was an increase in popularity of Facebook video traffic — a whopping 350% increase in volume since the November 15th launch — the most growth of all Facebook traffic".
