Problems solved by technology

However, because the traffic is dynamic and bursty, the traffic sharing cannot guarantee the utilization rate of each link. That is, there may be a certain period of time when a link has a large amount of traffic, and another link is a small amount of traffic. flow or no flow

Embodiment Construction

[0098] A data transmission method, a sender device, and a receiver device provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0099] The embodiment of the present application is applied to the field of data transmission, and can be applied to data interaction between at least two devices, such as routers, switches, etc., for example but not limited to data transmission in an Eth-Trunk scenario.

[0100] The technologies or terms involved in the embodiments of the present application are described below.

[0101] The link aggregation technology is a way to effectively increase the link bandwidth between two devices by bundling multiple physical links together into a logical link without hardware upgrades. Among them, the logical link is also called link aggregation group (link aggregation group, LAG). Each aggregation group corresponds to only one logical interface, which can be used as an ordinar...

Abstract

The embodiment of the invention discloses a data transmission method, and is used for providing a data transmission method for realizing load sharing balance of multiple links and avoiding disorder ofdata packets. The method provided by the embodiment of the invention comprises the steps of receiving service data; dividing the service data into a first data block and a second data block accordingto the sequence of the data packets in the service data; allocating a first link and a second link to the first data block and the second data block respectively; generating a merging rule, wherein the merging rule is used for indicating data block sorting of the first data block and the second data block, and the data block sorting corresponds to sorting of data packets in the service data; andsending the merging rule to the receiver equipment, and sending the first data block and the second data block to the receiver equipment through the first link and the second link respectively, so that the receiver equipment receives the first data block and the second data block respectively, and merges and recovers the first data block and the second data block into service data according to thedata block sequence indicated by the merging rule.

Description

technical field [0001] The present application relates to the field of data transmission, and in particular to a data transmission method, a sender device, and a receiver device. Background technique [0002] Ethernet link aggregation (Eth-Trunk) is referred to as link aggregation, such as figure 1 Shown is a schematic diagram of link aggregation, which bundles multiple Ethernet physical links together to form a logical link, that is, a link aggregation group (link aggregation group, LAG), so as to achieve the purpose of increasing link bandwidth. At the same time, these bundled links can effectively improve link reliability through mutual dynamic backup, and each link can realize load sharing. [0003] Since an Eth-Trunk link includes multiple member links, when transmitting data between devices, in order to improve efficiency, the transmitted data needs to be allocated to each member link for transmission, that is, the load needs to be allocated to each link . Currently...
