Problems solved by technology

[0002] Streaming data is data that can be transmitted on the network in the form of streaming transmission. The traditional backbone network is built on the basis of a multi-level network structure. When transmitting streaming data, the transmission link is too long and there are too many intermediate nodes. , the transmission process is extremely complex, on the one hand, it will lead to high transmission delay; on the other hand, when a link in the transmission process fails (for example, a node is encroached by traffic from other directions), it will cause the stream data transmission to be disconnected , weak anti-interference ability
If cross-operator transmission is involved in cross-domain transmission, it will directly lead to poorer transmission quality of stream data due to the problems of routing transit and bandwidth incompatibility
[0003] In live video applications or remote camera applications, the transmission performance requirements for streaming data are relatively high, but the traditional backbone network for cross-domain transmission cannot meet this requirement
Especially when streaming data is transmitted during peak hours, the transmission quality is difficult to guarantee

Embodiment 1

[0089] refer to figure 1 , which shows a schematic flowchart of the steps of the method for cross-domain transmission of streaming data according to Embodiment 1 of the present invention, which may specifically include the following steps:

[0090] Step 101, acquire stream data requested for transmission.

[0091] The stream data is data that can be transmitted on the network in a stream transmission manner, and the stream data can be transmitted from one node to at least one transmission node. The main transmission node is one of the transmission nodes used to transmit streaming data. The main transmission node can be composed of at least one server, and at least one main transmission node is deployed in an area. The networks of different main transmission nodes can be composed of different networks Provided by the operator, the main transmission node can establish a connection with at least one sub-transmission node, and the sub-transmission node can establish a connection ...

Embodiment 2

[0122] refer to figure 2 , which shows a schematic flowchart of the steps of the method for cross-domain transmission of stream data according to Embodiment 2 of the present invention, which may specifically include the following steps:

[0123] Step 201, acquire stream data requested for transmission.

[0124] Step 202: Receive a transmission path from the first primary transmission node to the second primary transmission node selected by the management node.

[0125] In the embodiment of the present invention, the management node may select a transmission node for the streaming data. The transmission path refers to the path formed by intermediate transmission nodes and communication cables from one main transmission node to another main transmission node. The first main transmission node may transmit the streaming data to the second main transmission node in the second area through one or more transmission paths. The first primary transmission node may send a request for...

[0158] refer to image 3 , which shows a structural block diagram of an apparatus for cross-domain transmission of streaming data according to Embodiment 3 of the present invention. The main transmission nodes deployed in multiple areas are connected by communication cables, and may specifically include the following modules:

[0159] An acquisition module 301, configured to acquire stream data requested for transmission;

[0160] The first transmission module 302 is configured to transmit the flow data from the first main transmission node in the first area to the second main transmission node in the second area via the communication cable;

[0161] The second transmission module 303 is configured to transmit the stream data from the second main transmission node to at least one sub-transmission node in the second area.

[0162] Preferably, the main transmission nodes in two adjacent target areas are connected using the communication cable, so that all the main transmission ...

Abstract

The invention discloses a cross-domain transmission method, device and system of stream data. The method comprises the following steps: acquiring the data stream required to transmit; transmitting the stream data from a first main transmission node of a first region to a second main transmission node of a second region through a communication cable; and transmitting the stream data to at least one sub-transmission node in the second region from the second main transmission node. According to the embodiment of the invention, the transmission process is greatly simplified, the cross-domain transmission efficiency is improved, the problem that the transmission delay is relatively high due to long chain and more nodes of a conventional trunk network is overcome, and meanwhile, the anti-jamming capability is greatly improved. The defect of transmission disconnection caused by problems of some node in a complex transmission process of the trunk network can be overcome, and the transmission quality of stream data transmission in the scenes of cross-domain and cross-carrier transmission, peak period and the like is guaranteed.
