Data exchange system and data exchange method

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 red
