Abstract: 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.

Abstract: Provided in the embodiments of the present disclosure are a method and device for processing a data packet, a storage medium, and an electronic device. The method includes: in a case where a Bit-Forwarding Ingress Router (BFIR) performs Bit Index Explicit Replication (BIER) packet encapsulation and outer Internet Protocol Version 6 (IPv6) packet encapsulation on a data packet, copying an Entropy field in a BIER packet header to a position of a Flow Label field of an outer IPv6 packet, and placing a label value allocated for Virtual Private Network (VPN) data in a position of the original Entropy field in the BIER packet header; and setting a data packet after the BIER packet header, and setting a Proto field in the BIER packet header to a corresponding value indicating a data packet type of the data packet.

Abstract: Provided are a multicast traffic transmission method and apparatus, a communication node and a storage medium. The multicast traffic transmission method includes the following. A first forwarding entry is determined, where the first forwarding entry includes Bit Indexed Explicit Replication (BIER) information of an Autonomous System Border Router (ASBR); multicast traffic is acquired; and the multicast traffic is encapsulated based on the first forwarding entry, and a BIER packet is determined and transmitted.
