Abstract: Provided in the present disclosure are a method and device for advertising information in a bridge network, a common attributes management component and a computer-readable storage medium. The CAMC is configured at each port of each node of the bridge network and is configured between a link-local registration protocol (LRP) application and an LRP. The method includes: the CAMC receives first common attribute information advertised by the LRP application and writes the first common attribute information into a database of the LRP; the CAMC receives second common attribute information reported by the database of the LRP and reports the second common attribute information to the LRP application.

Abstract: The embodiments of the present disclosure provide a data packet processing method and apparatus, a storage medium and an electronic device. The method includes that: a Bit Index Explicit Replication (BIER) Multicast Identifier (BMID) information of a data packet is set, wherein the BMID information is used for indicating a multicast channel to which the data packet belongs; and the BMID information is sent to a Bit-Forwarding Ingress Router (BFIR). Through the solution in the embodiments of the present disclosure, the technical problem in the related art that a node receives duplicate data packets is solved, duplicate data packets may be prevented, and data transmission efficiency is improved.

Abstract: The present application provides a redundant path resource reservation method, a network device, and a storage medium. The method includes: acquiring, from a received attribute declaration packet of a talker device, a TSN service targeted by the attribute declaration packet and an indication of whether to provide redundant propagation for the attribute declaration packet; duplicating the attribute declaration packet in response to the indication of providing the redundant propagation 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 duplicated attribute declaration packet, to establish a redundant path for the TSN service between the talker device and a listener device; and performing, in response to receiving a resource reservation request packet for the TSN service from the listener device, redundant path resource reservation for the TSN service.

Abstract: A port resource reservation method, an electronic device, and a storage medium are disclosed. The method may include, receiving a request message for reserving a resource for traffic, and determining a mode for resource reservation according to the request message; in response to a determination that resource reservation is to be performed in an extended mode, acquiring, according to a predetermined first mapping relationship, an egress port queue corresponding to an extended priority carried in the request message, and performing resource reservation for the traffic on the egress port queue corresponding to the extended priority, wherein the first mapping relationship refers to a mapping relationship between the extended priority and the egress port queue; and acquiring a traffic identifier from the request message, and establishing a second mapping relationship, wherein the second mapping relationship refers to a mapping relationship between the traffic identifier and the extended priority.
