Embodiment 1
[0054] Embodiment 1 provides a data distribution method, such as image 3 shown, including:
[0055] Step S301 , determining each valid lower-level node whose receiving status is normal in the distribution cycle.
[0056]In Embodiment 1, the upper-level node of the system periodically distributes the data to be distributed to its lower-level nodes.
[0057] When the distribution period arrives, according to the locally stored receiving status information of the lower nodes in the system, each effective lower node whose current receiving status is normal is determined.
[0058] The upper-level node can periodically send broadcast messages to all its lower-level nodes to determine whether the receiving status of each lower-level node is normal. The cycle of sending broadcast messages is independent of the above-mentioned distribution cycle, and there is no necessary relationship. After the upper-level node sends a broadcast message, if it receives a response message from the l...
Embodiment 2
[0077] Embodiment 2 provides a data distribution method, the flow chart of which is as follows Figure 4 shown, including:
[0078] In step S401, in the second embodiment, the upper-level node of the system periodically distributes the data to be distributed to its lower-level nodes.
[0079] Step S402, when the current distribution cycle arrives, the upper-level node determines the total amount of data to be distributed in the current distribution cycle, and then determines that the current amount of data to be distributed is the total amount of data to be distributed in the current distribution cycle minus The amount of data distributed.
[0080] Step S403, in the second embodiment, the upper-level node can determine the valid lower-level nodes currently receiving data according to the set circular linked list of lower-level nodes, wherein the circular linked list is a closed-loop linked list composed of each valid lower-level node linked one by one, that is, a circular lin...

Abstract
The method discloses a data distribution method and a device thereof. The method comprises the following steps: a parent node stores data to be distributed in a distribution period; and when the distribution period expires, the parent node distributes data of the data size which is not greater than the current processing capacity to a child node according to the data quality which can be currently processed by the child node and the data quality to be distributed. .The method and the system can help realize that the parent node distributes the data to the child node in batches according to the data quality which can be currently processed by the child node, which improves the data distribution efficiency and balance the load of various child nodes, thus improving the overall performance and the efficiency of the systemdata processing.
Description
technical field [0001] The present invention relates to the communication field, in particular to a data distribution method and system. Background technique [0002] With the continuous development of telecommunication services, the requirements for the processing capability of the service system are also constantly increasing. At present, the processing capability of the service system is mainly improved by forming a system with multiple nodes. figure 1 Shown is a schematic diagram of a multi-node communication system structure, a multi-node communication system composed of upper-level nodes and lower-level nodes 1-n, wherein the lower-level node 2 serves as the upper-level node, and can also form a node with its lower-level nodes A-N Hierarchical multi-node communication system. In this system, the upper-level node receives the data sent to the system, and then distributes the data to its multiple lower-level nodes for processing. [0003] The existing data distribution...
