The invention discloses an end-network cooperative reliable multicast method and system, and relates to the technical field of artificial intelligence distributed computing and high-performance network communication. The method specifically comprises the following steps that: a sending end analyzes a target expert set output by a hybrid expert model in a gating manner, constructs a layered multicast bitmap comprising a network node bitmap and a local expert bitmap, and packages the layered multicast bitmap in a message extension header for sending; and the switching equipment analyzes the network node bitmap in the message extension header, executes parallel bitwise AND operation with a locally preset port bitmap mask, determines a target port set needing to be forwarded, and executes message copying and path pruning. The invention aims to solve the problem of highly dynamic target set distribution in a hybrid expert model scene through source end bitmap coding and a switch hardware pruning mechanism, and significantly reduce system overhead and long-tail delay while ensuring high-reliability transmission.

The present invention provides improved solutions for reliable physical channel, such as physical downlink shared channel (PDSCH) reception during wireless communications, such as 3GPP New Radio (NR) communications, including: continuous channel repetition across slot boundaries, channel repetition with multiple frequency hopping, and joint repetition channel estimation using demodulation reference signals from at least two channel repetitions for channel estimation. In one aspect, reliable PDSCH reception can have the benefit of helping target UEs and serving base stations achieve reliable multicast and broadcast services (MBS).

Provided are systems, methods, and apparatuses for efficient propagation of multicast traffic in multi-path HPC networks. In one or more examples, the systems, devices, and methods include receiving, from a first switch at a second switch, an encapsulated packet comprising information that includes a route to the second switch; obtaining a source packet from the encapsulated packet based on de-encapsulating the encapsulated packet; and transmitting a first copy of the source packet to a first node of the second switch based on copying the source packet.
