Abstract: An information transmission method, comprising: a control platform generating forwarding information of a bit indexed explicit replication (BIER) network; and the control platform sending, according to the forwarding information of the BIER network, a BIER flow table to a forwarding device through an OpenFlow protocol. The solution solves the problems that, in a forwarding mode for a multicast message in the relevant OpenFlow technology, a space occupied by an entry is larger and the forwarding efficiency is lower because it is necessary to establish a corresponding flow table and group table on each forwarding device for each flow.
