Cross-domain transmission method and apparatus of streaming data

Abstract

The invention discloses a cross-domain transmission method of streaming data. Main transmission nodes separately deployed in a plurality of areas communicate with one another through communication cables, and the method comprises the following steps: receiving a transmission path acquisition request sent by a first main transmission node of a first area; selecting a transmission path from the first main transmission node to a second main transmission node of a second area, wherein the selected transmission path satisfies set requirements; and sending the selected transmission path to the first main transmission node, so that the first main transmission node transmits streaming data according to the transmission path. By adoption of the cross-domain transmission method disclosed by the embodiment of the invention, the transmission process is greatly simplified, the cross-domain transmission efficiency is improved, the problems of relatively high transmission delay caused by long links and numerous nodes of the traditional backbone network, meanwhile the anti-interference ability is greatly improved, and the transmission quality of the streaming data in cross-domain, cross-operator transmission, high-peak time period and other scenes is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for cross-domain transmission of stream data and a device for cross-domain transmission of stream data. Background technique [0002] Flow data is data that can be transmitted on the network in a streaming manner, and the cross-domain transmission of flow data between cities needs to be realized by using a traditional backbone network (Backbone Network). The backbone network is a high-speed network used to connect multiple regions or regions, and the carrying capacity of the backbone network becomes a bottleneck affecting data transmission performance. [0003] The traditional backbone network is built on the basis of a multi-level network structure. When transmitting stream data, the transmission process is extremely complicated because the transmission link is too long and there are too many intermediate nodes. On the one hand, it will cause high transmi...

Problems solved by technology

[0003] The traditional backbone network is built on the basis of a multi-level network structure. When transmitting stream data, the transmission process is extremely complicated because the transmission link is too long and there are too many intermediate nodes. On the one hand, it will cause high transmission delay; On the one hand, when there is a problem in one link during the transmission process (for example, a node is invaded by traffic from other directions), it will lead to disconnection of streaming data transmission, and the anti-interference ability is weak

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

[0004] 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

Moreover, the transmission path between transmission nodes is usually set in advance, which is not flexible enough to adjust the transmission path according to actual needs. Once there is a problem with the set transmission path, it will affect the transmission of stream data
