Embodiment 1

[0023] refer to figure 1 , shows a flow chart of steps of a method for selecting a transmission path according to Embodiment 1 of the present invention.

[0024] The transmission path selection method provided by the embodiment of the present invention includes the following steps:

[0025] Step 101: For each transmission path, determine the number of first heartbeat packets received by the storage node in each transmission path within a preset time.

[0026] Among them, the heartbeat packet of the transmission path is obtained by the collection node, and transmitted to the storage node through the forwarding node.

[0027] It should be noted that the preset time can be set to 1s, 2s, 3s, etc., and no specific setting is made for this.

[0028] A plurality of transmission paths are stored in the collection node, and the number of first heartbeat packets received by the storage node from the forwarding node in the transmission path is obtained and the number of first heartbea...

Embodiment 2

[0040] refer to figure 2 , shows a flowchart of steps of a method for selecting a transmission path according to Embodiment 2 of the present invention.

[0041] The transmission path selection method provided by the embodiment of the present invention includes the following steps:

[0042] Step 201: For each transmission path, determine the number of first heartbeat packets received by the storage node in each transmission path within a preset time.

[0043] Wherein, the heartbeat packet of the transmission path passes through the collection node, the forwarding node, and the storage node in sequence.

[0044] It should be noted that the preset time can be set to 1s, 2s, 3s, etc., and no specific setting is made for this.

[0045] A plurality of transmission paths are stored in the collection node, and the number of first heartbeat packets received by the storage node from the forwarding node in the transmission path is obtained and the number of first heartbeat packets is ...

Embodiment 3

[0075] refer to image 3 , shows a structural block diagram of a device for selecting a transmission path according to Embodiment 3 of the present invention.

[0076] The transmission path selection device provided by the embodiment of the present invention includes: a determination module 301, configured to determine, for each transmission path, the number of first heartbeat packets received by storage nodes in each transmission path within a preset time; wherein, the transmission path center The jump packet is acquired by the collection node and transmitted to the storage node through the forwarding node; the first availability value calculation module 302 is used to calculate the first availability value of each transmission path according to the number of each first heartbeat packet; the acquisition module 303, For each transmission path, obtain the second number of heartbeat packets received by the forwarding node in each transmission path; the second availability value c...

Abstract

The invention provides a transmission path selection method. The method comprises the following steps: for each transmission path, determining the number of first heartbeat packets and the number of second heartbeat packets received by a storage node in each transmission path within the predetermined time; calculating a first availability value and a second availability value of each transmission path; for each transmission path, determining a third availability value corresponding to the transmission path according to the first availability value and the second availability value corresponding to the transmission path; and selecting a transmission path corresponding to a maximum value in the third availability value corresponding to each transmission path to carry out data transmission. Thus it can be seen that, a transmission path selection scheme provided by the embodiment of the invention calculates the availability values of each transmission path, and takes the transmission path with high availability values as the current transmission path, so that the availability and reliability of the selected transmission path can be ensured; and the above method can reduce data loss as much as possible and enhance user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission path selection method and device. Background technique [0002] In the data acquisition system, there are generally three types of nodes: acquisition nodes, forwarding nodes and storage nodes. The data is generated from the collection point, aggregated and forwarded through the forwarding node, and finally enters the storage node for final storage of the data. [0003] In this process, data needs to be transmitted through the transmission path. During the transmission process, failures due to various reasons, such as equipment failure, node unavailability, or equipment unavailability, may cause data loss. This is unacceptable for some applications or businesses that require high data accuracy, because data loss will affect normal business operations. For example, for applications that calculate system availability, the tolerance for data loss is ver...
