DATA TRANSMISSION METHOD AND APPARATUS IN OPTOELECTRONIC HYBRID NETWORK

摘要

The present disclosure relates to a data transmission method and apparatus in an optoelectronic hybrid network. The method is: receiving an RDMA transmission request, and determining an RDMA transmission type and a to-be-transmitted data volume for data transmission according to the RDMA transmission request; determining a preset encapsulation format corresponding to the RDMA transmission type for data transmission and the to-be-transmitted data volume for data transmission; receiving to-be-transmitted data and encapsulating the to-be-transmitted data into a to-be-transmitted data packet of the determined preset encapsulation format; selecting a switching link for data transmission from an optical switching link and an electrical switching link according to a size of the to-be-transmitted data packet; and sending the to-be-transmitted data packet to a peer end based on the selected switching link for data transmission. Therefore, a proper switching link can be selected each time RDMA transmission for data transmission is performed.
