Problems solved by technology
[0004] For the existing transmission packet loss situation, it generally occurs in the following two situations: the traffic exceeds the network load and the network bearer quality is not good
Once the transmission packet loss is caused by poor network bearer quality, the use of flow control operations cannot solve the problem of transmission packet loss, but will cause a large amount of unnecessary business loss due to flow control

Embodiment Construction
[0032] In the data transmission processing method and device applied to multi-path networking in the specific embodiments of the present invention, it is used to perform data transmission between the first network element and the second network element, and there is a network between the first network element and the second network element. When there is no path recorded as congested, the path not recorded as congested is used to transmit the data packet to be transmitted, and when all transmission paths between the first network element and the second network element are congested, flow control is enabled for congestion processing.
[0033] The data transmission processing method applied to multi-path networking according to the embodiment of the present invention is used to process reliable data transmission between the first network element and the second network element, and between the first network element and the second network element There are multiple transmission pat...

The invention provides a data transmission processing method and a device applied in multipath networking. The method comprises the following steps: recording the congestion state of the multiple transmission paths, judging whether all the transmission paths occur congestion according to the recorded congestion state of the transmission paths and obtaining a judging result; selecting a transmission path used for transmitting data packet to be transmitted from a second transmission path when the judging result indicates that only part of the transmission paths are congested in the multiple transmission paths, wherein the second transmission path is a transmission path in the multiple transmission paths except a first transmission path which is congested; selecting a transmission path used for transmitting data packet to be transmitted from the multiple transmission paths when the judging result indicates that all the transmission paths are congested in the multiple transmission paths and starting flow control. The invention can fully use the transmission bandwidth of a backup path, and avoid unnecessary service loss caused by starting of the congestion control strategy.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission processing method and device applied to multipath networking. Background technique [0002] The communication field has very high requirements for the stability and reliability of data transmission between network elements. In order to ensure the stability and reliability of transmission, operators usually deploy multiple transmission paths between two network elements to form redundancy. , that is: when a part of these transmission paths fails, the remaining transmission paths can still ensure the normal operation of services, and this redundancy method is used to prevent the instability of transmission from affecting the stable operation of network element equipment. [0003] In the existing communication network, the situation of transmission packet loss (network congestion) often occurs, and in the prior art, once the situation of transmission packe...
