MESSAGE HEADER PROCESSING METHOD AND APPARATUS, STORAGE MEDIUM AND ELECTRONIC DEVICE

Embodiments of the present disclosure provide a method and apparatus for processing a message header, a storage medium, and an electronic apparatus. The method comprises: processing fields in an IPv6 message header according to fields in a Bit Indexed Explicit Replication (BIER) message header by using at least one of the following manners: the BIER message header is taken as a type of a Routing extension header of the IPv6 message header, and a Segments Left field in the IPv6 message header is processed according to a predefined manner; the BIER message header is taken as a type of other extension headers of the IPv6 message header, wherein the types of the other extension headers include a new option as a Hop-by-Hop extension header; a Bit-Forwarding Router Prefix (BFR-Prefix) of the BIER message header is filled in a Source Address (SA) field of the IPv6 message header; and a Bit Index Forwarding Table Index (BIFT-ID) field in the BIER message header is embedded into a target field of the IPv6 message header. The method solves the problems in the related art such as optimization cannot be effectively achieved in a process of combined encapsulation of a BIER message and an IPv6 message.
