Title:
REDUNDANT PATH RESOURCE RESERVATION METHOD, NETWORK DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/007828
Kind Code:
A1
Abstract:
The present application provides a redundant path resource reservation method, a network device, and a storage medium. The method comprises: from the received attribute declaration packet of a talker device, obtaining a TSN service targeted by the attribute declaration packet and an indication of whether redundant propagation needs to be provided for the attribute declaration packet; copying the attribute declaration packet in response to the indication that the redundant propagation needs to be provided for the attribute declaration packet, and there are at least two spanning tree instances maintained in a bridge device; propagating the received attribute declaration packet and the copied attribute declaration packet on the basis of the at least two spanning tree instances, so as to establish a redundant path of the TSN service between the talker device and a listener device; and performing redundant path resource reservation on the TSN service in response to the reception of a resource reservation request packet, from the listener device, for the TSN service.
