Abstract
The invention discloses a multipath sending control method and a multipath sending control system in a distributed network. The method and the system are applied to a distributed network. The distributed network comprises a server, a terminal device, an access device, and at least two storage devices. The terminal device supports service message receiving and sending on two or more transmission sub-flows. According to the method, the terminal device uses a first transmission sub-flow and a second transmission sub-flow to send a service message to the access device so the access device can forward the received service message to a first storage device and to a second storage device. At least two storage devices are used to store data, and the terminal device uses at least two transmission sub-flows in the process of sending data to the storage devices. Thus, the uplink speed can be maximized on one hand, and on the other hand, the QoS of one transmission sub-flow can be controlled during service control to reduce the overhead of a control signaling.
