Subject: Talk by Kave Salamatian in NRG: April 10 at 11

Hi Cody and all:

On Monday April 10 we will host Kave Salamatian (Univ. Savoie) who is well known in the networking community for his interesting analyses of many aspects of the Internet, including security, privacy, topology and traffic.   He has also worked in information theory, network coding, and statistical inference.   He will present on “Scratching below the Surface of the Internet: the Penetration of US Trackers in China.”

Cody – can you arrange this as an NRG talk, and publicize?    Please let students know they are welcome to meet with him as well.

All -- please let me know if you would like some 1-1 time with Kave.   Beside the work described below, Kave is currently working in areas including spectral graph analysis, network function virtualization, network economics (adwords), and TCAM optimization.   So I expect that there are interesting things to talk about with him for everyone!.

Also, if you would like to join us for lunch, please let me know.


Scratching below the Surface of the Internet: the Penetration of US Trackers in China

Kave Salamatian, Univ. Savoie

Abstract- China has developed a strong industry of digital services. Local corporations such as Alibaba, Tencent or Baidu, dominate the national landscape, with a market share of more than 75% in most sectors. We show in this paper that surprisingly, the underlying trackers are mostly american even on Chinese services, which are hosting less than 20% of Chinese trackers. Although this peculiarity of the Chinese web had already been observed before, our results provide much more insights into the interdependencies of US and Chinese platforms. Our analysis is based on a large DNS trace, of 150 billion records, provided by a major ISP offering both mobile and landline ADSL in China. DNS is a critical component of the Internet architecture, on which all web based applications, that constitute the large majority of current Internet traffic, rely. After some delicate treatment of the data to correct the biais caused by the technology of DNS caches and Network Address Translation, we were able to obtain precise measures of Internet traffic, site audience, and tracker usage. The results, best shown in the dataviz bilevel partition of the Top 20 domains of China, are critical for the economy of the ad industry, privacy protection rules, as well as cyber security.
