Problems solved by technology

[0010] When the sequential transmission method is used for many-to-one data transmission, in some application scenarios, the network performance will drop sharply due to link packet loss, and the throughput rate is far lower than the link bandwidth, causing the entire network bandwidth resource waste of
And when there is a large amount of data or many-to-one transmission, congestion problems are prone to occur
[0011] When using the data transmission sequence determined by the machine for data transmission, it is necessary to determine the data transmission sequence table, which not only increases the workload in data transmission, but also when the network scale is large, the table will be relatively large and complex, and multiple nodes simultaneously Sending a message to a node, if the communication load is not scheduled or the scheduling method is unreasonable, then the node receiving data needs to frequently process the request for receiving data, but cannot process the request for sending data, and problems such as fairness and congestion will occur in the network

Embodiment 3

[0077] In the same network, there are 8 nodes connected end to end in a ring, numbered from 0-7, and the data packets to be sent are numbered according to the number of the destination node of each data packet.

[0078] Among them, the data packets to be sent by node 0 are numbered according to data packet 1, data packet 2, data packet 3 ... data packet 7, that is, data packet 1 corresponds to the data packet sent to the destination node 1, and data packet 2 corresponds to the data packet sent to the destination node 2, and so on, the data packet 7 corresponds to the data packet sent to the destination node 7.

[0079] The data packets to be sent by node 1 are numbered according to data packet 2, data 3 ... data packet 7, data packet 0, data packet 2 corresponds to the data packet sent to the destination node 2, and so on, data packet 0 corresponds to the destination node 0 packets.

Abstract

The invention provides a large-scale network transmission optimization method and system and is characterized by that the method comprises following steps of connecting N nodes in a same network end to end, thus forming an annular structure, wherein each node is connected with adjacent nodes at two sides of the node and is connected with another adjacent nodes of the adjacent nodes. According to the method and the system provided by the invention, the data transmission method in combination of an annular network topology structure and a polling algorithm is provided; the large-scale network transmission is optimized; the problems such as disorder and congestion in data transmission are solved or partially solved; and the method and the system are applicable to data transmission among nodes in a big data environment.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a large-scale network transmission optimization method and system. Background technique [0002] Beowulf cluster is a high-performance parallel computer cluster structure. It is a loosely coupled multi-processor system constructed by a group of independent computer systems. Each process in the system communicates with the network and transfers information through shared memory. , so as to realize distributed parallel computing. The Beowulf cluster is designed to enable general university computer science departments and small research institutions to build their own supercomputer systems capable of running billions of instructions per second. Beowulf cluster technology solves the problem of how to achieve high performance and high real-time computing system by using ordinary computers. In recent years, the Beowulf cluster system has developed rapidly, mainly because the ...
