Abstract
The invention discloses a service quality control method of a distributed network and a server. The method is applied to the server in the distributed network. The distributed network comprises the server, a terminal device, an access device and at least two storage devices. The terminal device supports transmitting and receiving of a service message on two or more than two transport substreams; and the terminal device sends the service message to the access device through a first transport substream and a second transport substream to enable the access device to forward the received service message to the first storage device and the second storage device respectively. The method is characterized in that the server sends modification strategy information to the access device to indicate the access device to modify uplink network resources occupied by the first transport substream and/or the second transport substream according to instructions of the modification strategy information. The method can carry out QoS control on one of the transport substreams, thereby reducing overhead of control signaling.
