RE: China’s Slow Transnational Network
by Jakob Heitz (jheitz) 03 Mar '20

I can corroborate that. I visited China in August 2019 and had terrible internet performance to sites outside of China. This was both with mobile and wifi at the homes of two friends, one in Heilongjiang and the other in Beijing. When I visited in February 2015, it was much better. Both times, I was using VNC on the company VPN. This does not use much bandwidth, but is quite latency sensitive. -----Original Message----- Date: Sun, 1 Mar 2020 21:00:05 -0800 From: Pengxiong Zhu <pzhu011(a)ucr.edu> Hi all, We are a group of researchers at University of California, Riverside who have been working on measuring the transnational network performance (and have previously asked questions on the mailing list). Our work has now led to a publication in Sigmetrics 2020 and we are eager to share some interesting findings. We find China's transnational networks have extremely poor performance when accessing foreign sites, where the throughput is often persistently low (e.g., for the majority of the daytime). Compared to other countries we measured including both developed and developing, China's transnational network performance is among the worst (comparable and even worse than some African countries). Measuring from more than 400 pairs of mainland China and foreign nodes over more than 53 days, our result shows when data transferring from foreign nodes to China, 79% of measured connections has throughput lower than the 1Mbps, sometimes it is even much lower. The slow speed occurs only during certain times and forms a diurnal pattern that resembles congestion (irrespective of network protocol and content), please see the following figure. The diurnal pattern is fairly stable, 80% to 95% of the transnational connections have a less than 3 hours standard deviation of the slowdown hours each day over the entire duration. However, the speed rises up from 1Mbps to 4Mbps in about half an hour. We are able to confirm that high packet loss rates and delays are incurred in the foreign-to-China direction only. Moreover, the end-to-end loss rate could rise up to 40% during the slow period, with ~15% on average. There are a few things noteworthy regarding the phenomenon. First of all, all traffic types are treated equally, HTTP(S), VPN, etc., which means it is discriminating or differentiating any specific kinds of traffic. Second, we found for 71% of connections, the bottleneck is located inside China (the second hop after entering China or further), which means that it is mostly unrelated to the transnational link itself (e.g., submarine cable). Yet we never observed any such domestic traffic slowdowns within China. Assuming this is due to congestion, it is unclear why the infrastructures within China that handles transnational traffic is not even capable to handle the capacity of transnational links, e.g., submarine cable, which maybe the most expensive investment themselves. Here is the link to our paper: https://www.cs.ucr.edu/~zhiyunq/pub/sigmetrics20_slowdown.pdf We appreciate any comments or feedback. -- Best, Pengxiong Zhu Department of Computer Science and Engineering University of California, Riverside

Vincent Celindro <vcelindro(a)nanog.org> Thu, Nov 21, 2019, 5:57 PM to NANOG-announce, nanog Dear NANOG Community, In NANOG tradition - The NANOG Program Committee (PC) is excited to announce that we are accepting proposals for all sessions at NANOG 79 in Boston, Massachusetts, June 1st - 3rd, 2020. As mentioned during the community meeting at NANOG 78 in San Francisco, the Call For Presentations, CFP, is now open all year round, for current and future meetings. Below is a summary of key details and dates for the CFP, which can also be found at https://www.nanog.org/meetings/nanog-79/submit-presentation/ Given by many of the industry’s top minds, presentations at NANOG meetings are meant to spark the imagination, encourage dialog, and drive new solutions to our greatest networking challenges. The PC is currently seeking proposals, and also welcomes suggestions for speakers and topics. Presentations may cover current technologies, soon-to-be deployed technologies, and industry innovation. Vendors are welcome to submit talks which cover relevant technologies and capabilities, but presentations should not be promotional, or discuss proprietary solutions. We understand you may have concerns regarding the COVID 19 coronavirus. To date, the areas of the world most impacted by the virus are outside the North American region, which NANOG serves. The NANOG Board of Directors and executive team are closely watching the latest news reports as information about the virus rapidly changes, and how this may or may not impact the upcoming conference. There is no information at this time that suggests we should cancel NANOG 79, but we assure you we'll keep the entire NANOG community up to date as information changes, and we learn more. The primary speaker, moderator, or author should submit a presentation proposal and abstract via the Program Committee Tool at: https://www.nanog.org/meetings/submit-presentation/ - Sign in with your Profile Account - Select the type of talk you propose to present, and complete the title and abstract Timeline for submission and proposal review: - Submitter enters abstract (and draft slides if possible) in Program Committee Tool prior to the deadline for slide submission. - PC performs initial review and assigns a “shepherd” to help develop the submission — within 2 weeks. - Submitter develops draft slides of talk if not already submitted with the initial proposal. Please submit initial draft slides early — the PC does not evaluate submissions until draft slides are available for review. A NANOG slide template as well as presentation guidelines are available here. https://www.nanog.org/participate/presentation-guidelines/ - Panel and Track submissions should provide a topic list and intended/confirmed participants in the abstract. - PC reviews the slides and continues to work with Submitter as needed to develop the topic. - Draft presentation slides should be submitted prior to the published deadline for slides (April 13th, 2020). - PC evaluates submissions to determine presentations for the agenda (posted by May 18th, 2020). - Agenda assembled and posted. - Submitters notified. - Final presentation slides must be submitted prior to the published deadline for slides (May 25th, 2020).

In fact, Great Canon (GC) [55] is such an in-path system. But it is known for intercepting a subset of traffic (based on protocol type) only. What’s more, GC has been activated only twice in history (the last one in 2015 [55]). ----------------------------------- AT&T security says otherwise: https://cybersecurity.att.com/blogs/labs-research/the-great-cannon-has-been… The Great Cannon is a distributed denial of service tool (“DDoS”) that operates by injecting malicious Javascript into pages served from behind the Great Firewall."

In fact, the three large carriers provide 98.5% of China’s total transnational bandwidth. We observe this across all the three large carriers, as well as one smaller carrier, CERNET(China Education and Research Network).

Those are good insights. Our first guess is censorship too, and we discussed the possibilities of censorship side effects in Section 5.1 *Censorship*. My guess is that it’s all the DDoS traffic coming from China saturating the > links. > In fact, Great Canon (GC) [55] is such an in-path system. But it is known for intercepting a subset of traffic (based on protocol type) only. What’s more, GC has been activated only twice in history (the last one in 2015 [55]). However, it might be the case that the in-path capability is re-purposed to perform general traffic throttling. If that is the case, they have done a good job because the throttling resembles natural congestion from the loss rate and latency point of view.
