Embodiment 1

[0045] Embodiments of the present invention provide a method for controlling data transmission, such as figure 2 Shown include:

[0046] S101. Obtain the peak time corresponding to the peak traffic of the access rings dual-hanging on the pair of two interconnected aggregation devices (full name in English: Base-Base, BB for short) within a specified time period.

[0047] It should be noted that, in actual applications, when controlling data transmission, the peak moment corresponding to the peak flow is analyzed based on the existing data, so as to predict the peak moment corresponding to the peak flow that may occur in the future.

[0048] S102. Obtain the downlink traffic relayed by each node on the access ring at a peak time.

[0049] It should be noted that, assuming that the access ring includes n nodes, the downlink traffic relayed by each node on the access ring at the peak time refers to the transmission from the n-1th node to the nth node at the peak time of downst...

Embodiment 2

[0116] An embodiment of the present invention provides a data transmission control device 10, such as Figure 16 Shown include:

[0117] The acquisition unit 101 is configured to acquire the peak moment corresponding to the peak traffic of the access rings dual-hanging on the BB pair within a specified period of time.

[0118] The obtaining unit 101 is further configured to obtain the downlink traffic relayed by each node on the access ring at the peak time.

[0119] The processing unit 102 is configured to determine the network element to which each node on the access ring belongs according to the downlink traffic of each node relayed at the peak time obtained by the obtaining unit 101; wherein, the network element includes a first converging device and a second The convergence device, the BB pair includes a first convergence device and a second convergence device, the core network is connected to the first convergence device through a main link, and the core network is conn...

Abstract

Embodiments of the present invention provide a method and device for controlling data transmission, which relate to the field of communication technology, and solve the problem that in the prior art, when transmitting downlink data, only the primary link in the transmission network carries the data, while the backup link The problem of low bandwidth resource utilization of the entire transport network due to idle roads. The method comprises: obtaining the peak moment corresponding to the peak traffic of the access ring double hung on the BB pair within a specified time period; obtaining the downlink traffic relayed by each node on the access ring at the peak time; For the downlink traffic of the relay at the peak time, determine the network element to which each node on the access ring belongs; when it is determined that the downlink data requested by the access device needs to be transmitted to the access device through any node belonging to the second convergence device , controlling the standby link to transmit the downlink data received from the core network to the node via the second converging device, and then transmit the downlink data to the access device through the node.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission control method and device. Background technique [0002] With the introduction of concepts such as "Internet +, Industry 4.0, and Smart City" and the popularization and application of smart terminals and cloud services, the scale and traffic of the network will increase rapidly. The number of nodes has increased to tens of billions. The field of network and information services is no longer limited to public users. More traditional services and industry applications have become emerging development fields of the Internet. And wireless access network interconnection protocol (full English name: Internet Protocol Radio Access Network, abbreviated: IP RAN) / packet transport network (English full name: PacketTransport Network, abbreviated: PTN) as the backhaul bearer network of the mobile network, the mobile terminal generated All traffic needs to f...
