Problems solved by technology

In this case, if the devices at both ends of the inactive stack link need to communicate (for example, the incoming port of the message is on the A device, and the outgoing port is on the E device), the data needs to be transmitted from one end of the entire stacki

Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0047] Such as figure 2As shown, a data transmission method according to the present invention is applied to a ring stacking system including multiple stacking devices, including the following steps:

[0048] Step 201: the stacking device selects one stacking link as the optimal link and the other stacking link as the non-optimal link from the two stacking links between itself and other stacking devices;

[0049] It should be noted that the optimal link is used by the stacking device to forward its own data to other stacking devices, and the non-optimal link is used by the ...

Abstract

The application discloses a data transmission method, stacking equipment and a stacking system, and is applied to an annular stacking system including a plurality of pieces of stacking equipment. Thedata transmission method includes the following steps: stacking equipment selects a stacking link from two stacking links from itself to other stacking equipment as an optimal link, and the other stacking link is a non-optimal link; when new data need forwarding, if current remaining bandwidth of the optimal link is sufficient, the stacking equipment utilizes the optimal link to forward data to other stacking equipment; and if the current remaining bandwidth of the optimal link is insufficient, the non-optimal ink is activated to forward data to other stacking equipment. According to the datatransmission method provided by the application, when the bandwidth of the optimal link is insufficient, the non-optimal link is used as a complement to forward data, thereby solving the problem of effective data transmission when the bandwidth is insufficient in an annular stacking system, reducing forwarding delay, and improving the bandwidth utilization rate of the stacking system.

Description

technical field [0001] The present invention relates to but not limited to data communication network technology, and in particular to a data transmission method, stacking equipment and a stacking system. Background technique [0002] With the rapid development of information technology and the rapid expansion of network scale, it is often difficult to accurately predict the future network scale in the current network planning. When the number of planned switch ports is not enough to meet the needs of network applications, it is best The number of ports of the switch can be increased without changing the original network planning topology, and at the same time, the burden of the network management is not increased. In order to meet the above requirements, the switch stacking technology came into being. The so-called switch stacking refers to connecting multiple stackable switches with cables through the stacking interface, so as to realize the expansion of the number of port...
