China-based participants connectivity
When Chinese consumers access internet sites that are located outside of China the traffic must pass through the “Great Firewall of China”. This government-run firewall inspects and blocks traffic. The net result is impaired connectivity and lower bandwidths.
Other things that have an impact on the connectivity to KUDO:
On the COM and EU servers the Chinese attendees' connectivity will be slower because of:
- Using a VPN, the traffic is routed to one of the VPN servers, then to us, so the data transfer (audio, video, screen-sharing) is slower;
- Chinese Government Firewall (without a VPN)- one of the many issues causing slow data transfer is that it uses Deep Packet Inspection to monitor the internet, which sometimes may cause packet loss, meaning that the requested data couldn’t make it to a user’s computer, or it arrives later;
- Limited peering capacity - this is the arrangement of traffic exchange between Internet service providers (ISPs);
- There are other factors, but these are the most important.
If you are having constantly multiple attendees from China on the COM or EU domains, then we can enable on request the China Relay. The China Relay is not required by clients accessing from areas not subject to internet filtering, like Hong Kong.
What is 'China Relay'?
The China Relay is basically an infrastructure that is deployed on the Chinese data centers to improve the connectivity and video bitrates of Chinese consumers who are connecting to KUDO sessions outside of China (COM, EU).
- Please note that there is a surcharge for the subscribed minutes from the China relay.
- Connectivity and media quality can depend on a number of factors, including the quality of the last mile, the traffic load on the ISP, and the performance of our data center. As such connectivity and media quality can never be guaranteed.
