SPN small particle channel lossless adjustment method, device, medium and equipment

The invention discloses an SPN small particle channel lossless adjustment method and device, a medium and equipment, and the method comprises the steps: building an SRv6 tunnel between a source node and a destination node which need to be adjusted, and determining an SID List of the SRv6 tunnel, the SID List comprises all SIDs of the SRv6 tunnel, and each SID corresponds to a node along the way; when an initial node receives an adjustment demand sent by a network manager, time slot and bandwidth adjustment of a small particle channel is carried out on each node of the SRv6 tunnel hop by hop from the initial node to a termination node, and after the adjustment of the initial node and each node along the way is completed, adjustment information is generated, and the adjustment information is sent to the terminal node. And the generated adjustment information is packaged in an SRH extension head of the SRv6 message and is sent to the next hop node, so that the next hop node carries out time slot and bandwidth ad
