Data exchange system and data exchange method

Abstract

The invention provides a data exchange system and a data exchange method. The system comprises a server, an access switch and a core switch, wherein at least one physical layer processing chip arranged in the access switch and at least one message exchange chip arranged in the core switch are directly connected through at least one data link layer processing chip, the physical layer processing chip is connected with the server, the physical layer processing chip is used for transforming formats of messages sent by the server on the basis of a physical layer-data link layer conversion protocol, the data link layer processing chip is used for performing corresponding process for the received messages according to message processing strategies, and the message exchange chip is used for exchanging the received messages. According to the data exchange system and the data exchange method, the optimization for message exchange processing procedures by a data center is achieved, the delay of message forwarding is reduced, and the communication capacity of the data center is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data exchange system and method. Background technique [0002] Data centers are used to accommodate computer systems and related components, such as communication and storage systems, and are an important infrastructure for enterprise informatization. The data center operates a communication network based on the IP protocol, which mainly includes: access switches, used to access different servers, such as application servers, database servers, Web servers, etc.; aggregation switches, used to connect multiple access switches in parallel The above is connected to the core switch; the core switch is used to provide high-speed switching backbone lines. [0003] In recent years, the flattening of the data center network architecture has been promoted, and the aggregation switch in the middle has been removed, so that the switching system of the...

Problems solved by technology

[0004] However, based on the switching system where the access switch and the core switch are interconnected through the physical layer Phy chip interface, the message needs to be processed multiple times at the physical layer and the data link layer in the process of realizing message exchange, which greatly increases the packet cost. The delay of file forwarding reduces the communication capability of the data center
