Provide facilities to mitigate "clogging" of networkSandvineReport issued by "Global Internet PhenomenaAccording to an Internet provider in North America, "Since updating of Apple has become available, iOS 7 downloads immediately account for 20% of the total network traffic, which is the total of 15 It accounted for% or more ". According to the report, in order to update to iOS 7 by wireless communication, it is necessary to download data of 760 MB for iPhone 5, 900 MB for iPad 2, 729 MB for Apple TV, and when updating from a computer via iTunes , It seems that it was necessary to download data size of 1.2 GB for iPhone and 1.4 GB for iPad.


The report says, "The very interesting thing is that the size of the entire traffic has grown significantly at the peak of network traffic.If several providers who are Sandvine's customers carefully monitor the traffic demand caused by iOS 7 And we will prepare for release of iOS 8 next year from these observations. "

Trends of overall traffic
Report created by Sandvine Global Internet Phenomena is investigating trends in overall network traffic besides iOS 7, according to which the existence of video streaming service still accounts for a large percentage of the total traffic. Among them, YouTube continues to increase traffic considerably, and seems to account for about 18.7% of download traffic at the peak. further,In North America, Netflix and YouTube account for about half of the total Internet traffic during peak hours, It was clarified several months ago, but now the traffic has become more than 50%.

This is the peak demand demand of network traffic in North America. Total usage of Netflix and YouTube in "Downstream (download traffic)" is 50.31%. Also, BitTorrent, which occupied a large proportion in traffic until a while ago, is about 7.4% of the total at peak time. Even with file sharing as a whole, the percentage of traffic as a whole is less than 10%.


This is a breakdown of peak traffic on mobile terminals. Although there is not so much change when compared with the past, it seems that how to use smartphones and tablets connected to home Wi - Fi etc seems to be increasing.


Also in the report it says that you should avoid lunch or evening if you want to watch YouTube with the best picture quality possible. The basis for that is the graph below. It shows that it is difficult to connect to YouTube in the time zone (graph blue frame portion) where the horizontal axis of the graph represents time and the vertical represents the data transfer rate and the red line of the graph is greatly down. Hulu of streaming video distribution service does not make it difficult to connect to the site during peak hours at night (20, 21 o'clock) and daytime (12, 13 o'clock), but on YouTube, which ISP (Internet service provider ) It seems that it was a problem also seen. The cause of this poor communication quality is caused by excessive access to YouTube's hosted Google server, and it is believed that it is due to conflict between the American lunch time and the peak time of European night.


In addition, only 1% of heavy users in the top tier account for 39.8% of the total upload traffic, and you can see by looking at the lower graph red frame part that heavy network is shown. Moreover, even if 50% of the light user layer that does not use much network is combined, it is understood that it is only 6.8% of monthly total traffic by looking at the blue frame part.
