Embodiment Construction

[0028] Embodiments of the present invention provide a data transmission method, device, and network element, which are used to solve the problem in the prior art that when only available links are considered in load balancing, when a link fails, other unfailed links before the link fails Technical issues of packet flow redistribution.

[0029] The implementation process and purpose of the solution in the embodiment of the present invention will be described in detail below.

[0030] A data transmission method provided by an embodiment of the present invention can be applied in a communication network system. Please refer to Figure 1a and Figure 1b As shown in FIG. 1 , it is a structural diagram of a possible communication network system provided by the embodiment of the present invention. Such as Figure 1a With the structure shown in , the communication network system includes network element 1 and network element 2 . There are n transmission channels from link 1 to li...

Abstract

A data transmission method, device, and network element, the method including: receiving a message; determining a first member link in a first group of member links according to a first decision-making method; if the first member link is unavailable , according to the second decision-making method, determine the second member link in the second group of member links; wherein, all the member links in the second group of member links are available, and the first group of member links including the second group of member links and unavailable member links; sending the message through the second member links. Through this method, after a link fails, the flow distributed on other unfailed links before the link fails will not be redistributed.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data transmission method, device and network element. Background technique [0002] Currently, network elements are interconnected by connecting optical modules to optical fibers. The price gap between optical modules of different rates is large. For example, the price of a 10 Gigabit small package hot-swappable transceiver (English: Small form-factor pluggable Transceiver, referred to as: SFP) is only 3.8% of the price of a 40Gigabit SFP. %. Driven by the price difference of optical modules, multiple low-speed links are usually selected to connect two network elements. Therefore, in the existing network, multi-links will be widely deployed, followed by multi-chain Road load balancing requirements and technologies. [0003] In the prior art, a network element adopts the following load balancing technology. After the network element receives the message, it...
