Data transmission system, data interface device and data transmission method for multiple servers

Abstract

The invention discloses a data transmission system, a data interface device and a data transmission method for multiple servers, belonging to the field of network communication. The data transmission system comprises a data interface device, a controller device and a full gloss exchange matrix, wherein the data interface device is used for receiving a data stream from a server and generating a forwarding request according to the data stream; the forwarding request comprises a destination address of the data stream; the controller device is used for generating a forwarding configuration signal according to the forwarding request; the full gloss exchange matrix is used for configuring a gloss exchange route between two data interface devices according to the forwarding configuration signal so as to forward the data stream to a server to which the destination address appoints; and the two data interface devices are data interface devices which are respectively connected with a resource server of the data stream and a server to which the destination address appoints. The data transmission system has a higher compatibility and is capable of realizing a zero hop access between any one server to another; and a lower networking cost is realized.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a data transmission system, a data interface device and a data transmission method used among multiple servers. Background technique [0002] With the rapid development and popularization of cloud computing, data center, as the carrier of computing and storage, its design and deployment method has become the focus of academic and industrial research. [0003] A data center usually includes a plurality of servers and a data transmission system arranged among the servers. Most traditional data centers adopt a two-layer tree structure including the core layer and access layer or a three-layer tree structure including the core layer, aggregation layer and access layer. This kind of tree structure has many disadvantages: on the one hand, the use of two-layer or three-layer multi-layer superposition architecture has disadvantages such as high cost of core switching equipment, large se...

Problems solved by technology

This kind of tree structure has many disadvantages: on the one hand, the use of two-layer or three-layer multi-layer superposition architecture has disadvantages such as high cost of core switching equipment, large service delay between multi-hop devices, and limited flexibility; On the other hand, most traditional data centers use Ethernet transmission technology, and the throughput rate of data transmission is relatively limited; on the other hand, traditional data centers do not have a unified control and management plane, and cannot consider data flow from the perspective of the entire network topology scheduling

[0005] However, first, the three components of the data transmission system must use the same series of supporting equipment, and the networking process does not support different products produced by different manufacturers, that is, the compatibility of the data transmission system is poor; second, Although this data transmission system can achieve one-hop reachability between any node and another node, it still cannot meet the demand for data transmission speed in some cases; third, the networking cost of applying this data center is relatively high
