Abstract: Disclosed is a method and device for transmitting video data. The method includes allocating a traffic to each piece of data to be transmitted at interval of a preset duration, and when a traffic that needs to be used by the data to be transmitted is larger than the traffic allocated to it, transmitting a part of the data to be transmitted using this allocated traffic, and transmitting the remaining data after a next traffic allocation is performed. By allocating traffic, the traffic for transmission can be controlled, thereby reducing possibility of network congestion caused by relatively large bandwidth being used for transmitting video resources. If the traffic that needs to be used by the data to be transmitted is larger than the traffic allocated to it, only part of the data is transmitted, and the remaining of the data will not be transmitted until traffic is allocated again.
