METHOD, SERVER AND APPARATUS FOR ESTABLISHING POINT-TO-POINT CONNECTION

When a first device is establishing a point-to-point connection with a second device, a server provides connection instructions for assistance. The connection instructions define multiple connection flows. When the connection instructions are received, the first device attempts a first connection flow under a priority order. If failed, another connection is tried by the first device. The server monitors connection status and adjusts the connection instructions according to statistics and circumstances.
