Method, device and system for self-adaptation multiple-link aggregation

Abstract

The invention provides a method, device and system for self-adaptation multiple-link aggregation. The method includes the steps of the step 1, distributing message numbers to messages in a dataflow to be sent, wherein the message numbers are increased sequentially along with the sending sequence of the messages, and the step 2, selecting one communication link for each message in a scheduling queue, carrying out MUDP packaging on the messages according to the communication links, and sending the messages subjected to the MUDP packaging to a receiving end through the communication links. According to the technical scheme, a single message serves as a triggering object for communication link selection, the defect that data transmission is carried out only through single dataflow in the prior art is overcome, the single dataflow can be transmitted through different communication links, the upper limit of available bandwidth of one dataflow is no longer limited by bandwidth of a single link, and therefore the multiple-link aggregation is achieved and communication speed and quality are improved; meanwhile, load balance of the multiple communication links is achieved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for adaptive multi-link aggregation. Background technique [0002] At present, informatization construction has become an important part of enterprise development. A large amount of office data needs to be transmitted in various branches of the enterprise. Big bottleneck. The network topology of most general-division enterprises has the following characteristics: (1) the headquarters uses multiple optical fiber links to connect to the Internet (Internet), and the link bandwidth is large, high-quality, and expensive; (2) the branch offices use multiple ADSL The link is connected to the Internet, and the link bandwidth is small, the quality is poor, and the price is low. Usually, there is cross-operator access between the branch and the headquarters; (3) The server is deployed on the internal network of the headquarters, and the branch uploads and dow...

AI Technical Summary

Problems solved by technology

Therefore, the multi-link egress load balancing function cannot solve the following two types of problems, which widely exist in the current network applications of general branch enterprises: (1) Branches often upload and download data with the headquarters server through the Internet, and the whole process is usually Data transmission through only a single stream

In this case, the multi-link egress load balancing function cannot make full use of the bandwidth of multiple links, resulting in the transmission process being limited by a single ADSL link, with slow transmission speed and long time-consuming; (2) A certain link between the branch and the headquarters Some key applications, such as video conferencing, usually have the characteristics of less data flow and long duration

When a link fails intermittently, although the multi-link egress load balancing function can route the data flow to another normal link when the key application is reconnected, it cannot guarantee that the key application will not be interrupted
