Abstract: A back drilling processing method for a circuit board includes: obtaining a board to be back drilled, wherein the board includes a target signal layer and at least two conductive reference layers; drilling a through hole at a set position of the board, and obtaining an actually measured spacing between two conductive reference layers; in response to a hole to be back drilled being of a first type, determining a target back drilling depth; controlling a drilling bit to drill for the target back drilling depth towards the target signal layer; in response to the hole to be back drilled being of a second type, determining a target relative height of a back drilling end point relative to a machine; and controlling the drilling bit to drill for the target relative height towards the target signal layer. The back drilling does not drill through the target signal layer.

Abstract: The present disclosure provides a message forwarding method, including: receiving a target message from an upstream device, the target message carrying first timeslot information including a first timeslot length and a first timeslot identifier; determining a second timeslot length and a second timeslot identifier according to the first timeslot length and the first timeslot identifier; and in response to that a preset waiting time elapses after the target message enters a cache queue corresponding to the second timeslot length and the second timeslot identifier, forwarding the target message. The present disclosure further provides a message forwarding device, and a computer-readable medium.

Abstract: Provided are a method and device for establishing a service path, an electronic apparatus, and a readable storage medium. The method includes: receiving request information for establishing a path for a service, where the request information includes a service type and a resource reservation scheme; computing a path for the service according to topology information of a FlexE link through which the service is transmitted and the request information; and reserving a resource and establishing a path for the service according to the service type and the resource reservation scheme, and a service type and a resource reservation scheme on a channel of the FlexE link through which the service is transmitted.

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: A method, a system and a storage medium for network failure protection belonging to the field of network technologies. The method comprises: allocating, for each forwarding link of the ring topology, a protection ring bit position opposite to the direction of a working path; newly adding BRFT for storing adjacent forwarding table entries related to forwarding along the direction of the protection ring bit position; and when a BIER message is forwarded along the working path, if a BFR detects that the downstream adjacency fails, searching for entry content of the BTAFT, finding the correlation between the link bit position of the fault forwarding link and the protection ring bit position, and forwarding, on the basis of entry content of the BRFT, the BIER message to the opposite end fault point of the opposite end along the direction of the protection ring bit position.
