Abstract

The embodiments of the present invention disclose a message forwarding method and apparatus applied to a software defined network (SDN), wherein the SDN comprises at least one controller and a plurality of servers. The method comprises the following steps that: link state information in the SDN is obtained; the load sharing table of the first server in the plurality of servers is generated according to the link state information and the address of the destination server of the first server in the plurality of servers; and the load sharing table is sent to a software switch on the first server so that the software switch on the first server can perform message forwarding according to the load balancing table. According to the message forwarding method and apparatus applied to the software defined network (SDN) provided by the embodiments of the present invention, the load sharing table is dynamically generated, and therefore, the forwarding efficiency of load balancing data can be improved, and the maintenance complexity of load balancing can be reduced.
