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.

Abstract: Provided is a message encapsulation and de-encapsulation method and device, a storage medium, and an electronic device. The message encapsulation method includes: encapsulating a bit indexed explicit replication (BIER) header in an IPv6 extended header of an IPv6 message in combination with a generic fragmentation header (GFH), a generic encapsulating security payload (GESP), or a generic authentication header (GAH). The problem in the related art of how to combine a GFH mechanism with a BIER header encapsulated in an IPv6 extended header can be solved; when the BIER header is encapsulated in the IPv6 extended header, the BIER header can be combined with the GFH/GESP/GAH, thereby simply and efficiently realizing fragmentation, encapsulating security and authentication functions of a BIER multicast message.
