Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] In the protocol stacks of general-purpose operating systems such as windows and linux, multicast groups are controlled and managed through the IGMP (Internet Group Management Protocol) protocol. Only the IGMP protocol directly communicates with the multicast host, and the router running IGMP is responsible for managing the joining and leaving of group members and maintaining group membership. For the IGMP message format, refer to the following table, including the version field, including the IGMP version identifier, currently there are three versions V1, V2 and V3; the type field, including membership query (0x11), membership report (0x12); checksum Field, used for the checksum of the...

Abstract

The invention discloses a multi-port multicast method, equipment and computer-readable storage medium. Wherein, the method includes: after joining the multicast group, configuring a multi-port list locally; matching the destination port in the received multicast message according to the multi-port list, and processing the multicast message when the matching is successful arts. The present invention does not need to establish a plurality of UDP sockets by configuring the multi-port list, reduces the creation of sockets, and reduces the management complexity of sockets in the application layer.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a multi-port multicast method, device and computer-readable storage medium. Background technique [0002] In the field of Internet transmission, with the development of multimedia video technology, the application of multicast transmission technology is more and more extensive, such as IPTV channel transmission, emerging VR (Virtual Reality, virtual reality) live broadcast technology, all use multicast to transmit media data . Moreover, these multicast transmissions need to support one channel of multicast and transmit multiple streams. For example, OTT (Over The Top) multicast transmission needs to transmit code streams of different bit rates, and VR multicast transmission needs to support the transmission of multi-view streams. [0003] The current windows and linux systems are attached to UDP sockets for the management of multicast groups. The UDP socket must s...
