Referring to fig. 7, in case of a failure of channel 1, switching to channel 2 or channel 3; in case one of the channels 2 or 3 fails, the other channel is switched to for data transmission. In addition, after the failed channel is recovered to be normal, the data transmission is carried out through the channel selected by the original downlink routing control strategy.
The embodiment of the application also provides a data transmission method applying the switching node routing control strategy, which comprises the following steps:
step 1, when the switching node B needs data, the global switching management system firstly detects the data to find that the data of the switching node A meets the requirement of the switching node B, and then the connection relation between the A and the B is established.
And 2, the switching node A is a data provider and is divided into a main node and a standby node, and the switching node B is a data demand side and is also divided into the main node and the standby node. The data is normally provided by the master node of the switching node a and received by the master node of the switching node B.
And 3, the main switching node A sends the data to a transmission node in the switching network, and if the main node has a problem, the main switching node A is automatically switched to a standby node.
And 4, the data on the switching node A is mounted on the transmission node, and the uplink route control strategy is transmitted through the main channel by default, if the main channel is not smooth, the data is automatically switched to the standby channel, and finally the data is transmitted to the transmission node close to the switching node B.
And 5, for the downlink route control strategy, calculating the proportion according to the flow condition by using at least two channels in each of the main channel and the standby channel. After the transmission channel finishes transmitting the data, the data is transmitted from the transmission node to the main node of the switching node B by default, if the main node has a problem, the data is automatically switched to the standby node, and the data transmission is finished.
Based on the same technical concept, the embodiment of the application also provides an electronic device, which is used for executing the data transmission method, and fig. 8 is a schematic structural diagram of an electronic device for implementing the embodiments of the application.
