The invention relates to a data exchange method and data exchange equipment. The method comprises the following steps: acquiring the service attribute information of the upstream and downstream of an exchange network module; converting the service attribute information into exchange control information; establishing a data exchange physical link according to the exchange control information and scheduling data; and utilizing the data exchange physical link to exchange the scheduled data. The equipment comprises an input processing module, the exchange network module and an output processing module, wherein the exchange network module comprises a data exchange sub-module and an exchange network scheduling sub-module, and further comprises a data exchange sub-module, an exchange network scheduling sub-module and a dynamic bandwidth allocation sub-module. Data exchange is controlled according to the service attribute information by acquiring the service attribute information, which simplifies a data exchange processing flow.
