Embodiment 1
[0089] Aiming at the problems existing in the wireless multi-network fusion UDP tunnel transmission technology, the present invention adopts MPTCP and UDP dual tunnels as the tunnel transmission technology between the integrated terminal and the aggregation server. In order to achieve sequential delivery and retransmission of multi-link IP service convergence transmission, in addition to the LLC over IP tunnel technology that uses UDP protocol as the multi-link ARQ mechanism of tunnel encapsulation to achieve retransmission in the previous analysis, another technical route is to use The MPTCP protocol is used as a technology for tunnel encapsulation.

[0118] 1. The specific implementation environment is as follows figure 2 shown.
[0119] 2. The process of detailed processing
[0120] 1) There are multiple links between the sender and the receiver. The current environment is implemented using three links, here are link 1, link 2 and link 3, and the delay of each link and bandwidth are different.
[0121] 2) The integrated terminal establishes two multi-link transmission tunnels with the convergence server after startup, one is the MPTCP multi-link transmission tunnel, the other is the UDP multi-link transmission tunnel, and starts the connection tracking of the three links of MPTCP The table stores the tunnel-encapsulated TCP data frames sent via each link.
[0122] 3) The integrated terminal sends detection request packets from the three links to the aggregation server, and records the sending time, and the aggregation server replies immediately after receiving it, and the integrated terminal can calculate the RRT time...
