Redundant path resource reservation method, network device and storage medium

A redundant path resource reservation method applicable to a talker device, comprising:

• generating, in response to determining to provide redundant path resource reservation for a time sensitive networking (TSN) service, a first attribute declaration packet for the TSN service, wherein the first attribute declaration packet carries an indication of providing redundant propagation for the attribute declaration packet;
• and
• sending the first attribute declaration packet to a bridge device connected to the talker device,
• wherein at least two spanning tree instances are maintained in the bridge device, and the at least two spanning tree instances are configured to establish a redundant path for the TSN service between the talker device and a designated listener device according to the indication of the first attribute declaration packet.

A redundant path resource reservation method applicable to a listener device, comprising:

• receiving, through a bridge device connected to the listener device, at least two attribute declaration packets for a same time sensitive networking (TSN) service;
• generating, in response to that the TSN service is a TSN service of interest to the listener device and each received attribute declaration packet is a packet propagated based on a different spanning tree instance, a resource reservation request packet for the TSN service and corresponding to the different spanning tree instance for each received attribute declaration packet, wherein the different spanning tree instance is one of at least two spanning tree instances maintained in the bridge device connected to the listener device, and the at least two spanning tree instances are configured to establish a redundant path for the TSN service between a talker device and the listener device;
• and
• sending, based on the different spanning tree instance corresponding to each generated resource reservation request packet, each resource reservation request packet to the bridge device connected to the listener device.
