Datasheet: OpenTok China Relay Use Cases | Benefits | Commercial Terms | Technical Specifications Overview In general, when Chinese consumers access internet services that are located outside of China, the traffic passes through a state operated firewall that can impair connectivity and bandwidth. The problem is particularly acute when OpenTok end-users in China are connecting to sessions located in other parts of the world. To remedy this situation and provide a better experience for these cross border sessions, additional OpenTok platform infrastructure is deployed to Chinese data centers. End-users in China automatically connect to this local infrastructure, which in turn routes to OpenTok media servers located elsewhere in the world. The net result is a higher quality of experience for those end-users located in China who are connecting with a session located elsewhere in the world.
