Problems solved by technology

This method can guarantee the order of packets, but when there are few types of packet flows or the traffic of each packet flow is uneven, the packets distributed to each sub-link will be unbalanced, resulting in some sub-links Link transmission utilization is low, which affects transmission efficiency

Embodiment Construction

[0015] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0016] see figure 1 , figure 1 It is a schematic flowchart of a data method provided by an embodiment of the present invention. The method mainly includes the following steps.

[0017] Step 102, determine the total delay time corresponding to each sub-link.

[0018] An aggregation link includes multiple sub-links, and the sending end sends a message to the opposite end (that is, the receiving end) through the multiple sub-links. The sending end determines the total delay time of each sub-link, that is, determines the total delay time required for all the packets on each sub-link to be transmitted to the peer end; for any sub-link, the sending end needs to determine the The total delay time required for all packets on the sub-link to be transmitted to the receiving end.

[0019] Step 104, select a sub-link, and transmit the message to be distrib...

Abstract

The embodiment of the invention provides a data sending method, which comprises the following steps of: determining total delay time required for totally transmitting message on each sub-link in an aggregation link to an opposite end; and selecting a sub-link according to the total delay time of the sub-links, and distributing the message to be distributed to the sub-link to perform transmission. The embodiment of the invention can effectively realize order preservation of message transmission and load balance of the sub-links, and improve the transmission efficiency. Moreover, the embodiment of the invention also provides a data sending device.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, in particular to a data sending method, device and communication system. Background technique [0002] In communication transmission, in order to increase the link capacity, the link bundling technology (Bonding) is introduced, the essence of which is to "combine" several physical links between the sending end and the receiving end into a logical aggregated link. Each physical link in the aggregated link is called a sub-link (or physical sub-link) of the aggregated link. An aggregated link is logically a whole, and its internal composition and transmission data are transparent to upper-layer services. At present, there are related protocol standards to bundle links, such as the ML-PPP protocol (Multi-Link Point To Point Protocol, multi-link point-to-point communication protocol) on the PPP protocol (POINT TO POINT PROTOCOL, point-to-point communication protocol) l...
