Embodiments of the present invention disclose a method, a duplication point device, a server, and a system for data flow reuse transmission. The method includes: receiving, by a duplication point device, a first data flow request message sent by a first user within a preset time period, receiving a second data flow request message sent by a second user within the preset time period and after receiving the first data flow request message, requesting the first data flow from a server after the current time reaches the end time, receiving the first data flow from the server, duplicating the first data flow, which results in two identical first data flows, and sending one to the first user and the other to the second user respectively. The method, the duplication point device, and the server for data flow reuse transmission provided by one aspect of the present invention does not require running a complicated multicast protocol on a plurality of devices and can achieve simpler and more efficient data flow reuse. |
