Problems solved by technology

[0005] In the existing stream reuse method, the server sends the data content to the users who need to reuse in the form of multicast. Since the multicast protocol needs to be run on multiple devices, the implementation is relatively complicated.

Embodiment 1

[0134] This embodiment provides a method for data flow reuse transmission, such as figure 1 As shown, the method includes:

[0135] 101. The replication point device receives a first data stream request message sent by a first user within a preset time period, the first data stream request message is used to request a first data stream, and the preset time period A segment is a time period between a starting moment and an ending moment, and includes the starting moment and the ending moment.

[0136] 102. The replication point device receives a second data stream request message sent by a second user within the preset time period and after receiving the first data stream request message, and the second data stream request message The stream request message is used to request the first data stream.

[0137] 103. The replication point device requests the first data stream from a server after the current time reaches the end time.

[0138] 104. The replication point device rec...

Embodiment 2

[0143] This embodiment provides a method for data flow reuse transmission, such as figure 2 As shown, the method is as follows.

[0144] 201. The replication point device receives a first data stream request message sent by a first user within a preset time period, the first data stream request message is used to request a first data stream, and the preset time period A segment is a time period between a starting moment and an ending moment, and includes the starting moment and the ending moment.

[0145] 202. The replication point device receives a second data flow request packet sent by a second user within the preset time period and after receiving the first data flow request packet, and the second data flow request packet The stream request message is used to request the first data stream.

[0146] 203. The replication point device requests the first data stream from a server after the current time reaches the end time.

[0147] 204. The replication point device receiv...

Embodiment 3

[0152] Such as image 3 As shown, another method embodiment is as follows.

[0153] 301. The replication point device receives the first data flow request message of the first user within a preset time period, where the preset time period is the time period between the start time and the end time, and includes all The start time and end time are stated.

[0154] 302. The replication point device receives a second data flow request packet of a second user within the preset time period and after receiving the first data flow request packet of the first user, the The second data flow request message of the second user is used to request the same data flow.

[0155] 303. The replication point device requests the data stream from the server after the current time reaches an end time.

[0156] 304. The replication point device receives the data stream from the server, and the replication point device replicates the data stream to obtain two identical data streams.

[0157] 305. ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data flow reuse transmission method, replication point equipment and system. Background technique [0002] Video data streams are usually high-bandwidth data streams, which have a greater demand for network bandwidth. In addition, large file download data streams also have greater demand for network bandwidth. As the types of high-bandwidth data streams increase and the number of users increases, the consumption of network bandwidth resources is also increasing, which can easily cause network congestion, reduce the quality of data stream delivery, and affect user experience. [0003] Currently, in order to optimize network bandwidth resources, a flow reuse method can be used. Stream reuse refers to the sharing of data traffic among users with the same request. In the traditional stream reuse technology, after receiving the same request from multiple users, the serv...
