Abstract: A bracket assembly, a battery rack and an energy storage container are provided. The battery rack main body is provided with multiple layers of battery storage areas for placing battery packs. The bracket assembly includes a plurality of first brackets configured to support and fix the battery packs. Each of the battery storage areas is mounted with a plurality of the first brackets. The plurality of the first brackets in the same battery storage area are arranged in multiple columns and multiple rows. Two adjacent first brackets in the same row are arranged in a staggered manner, so that two adjacent battery packs in the same row are arranged in a staggered manner.

Abstract: A package structure for a battery pack is provided. The package structure for the battery pack includes a tray structure and a cover body, the tray structure includes a tray body and a support portion. At least a part of the support portion protrudes from a periphery of the tray body in a planar extension direction of the tray body. The support portion cooperates with the tray body to form a groove located at the periphery of the tray body. The cover body is arranged on a first side of the tray body. A cavity is formed on a side, facing the tray body, of the cover body. The battery pack is located on the first side of the tray body and is accommodated in the cavity. At least a part of the cover body is lapped with the groove, and the tray body is accommodated in the cavity.

Abstract: This application relates to a network system, a network packet processing method and apparatus, and a storage medium. The network system includes a controller, a network device, and a terminal device. The terminal device is configured to: when the terminal device accesses a network, send a first packet to a network device connected to the terminal device. The network device is configured to: in response to the first packet sent by the terminal device, mark a connection type of a port connected to the terminal device as a first type; and in response to a topology query request sent by the controller, send a topology query response to the controller, where the topology query response includes an identifier or port information of the network device. According to embodiments of this application, network topology discovery performance can be improved.

Abstract: Embodiments of this application disclose a packet processing system and method, to perform network topology discovery and routing table delivery. The system includes a source node, an intermediate node, and a destination node. After receiving, from a first port, a first packet to be sent by the source node to the destination node, the intermediate node decodes the first packet to obtain a forwarding path of the packet and an identifier ID of the source node; and the intermediate node generates a first mapping relationship based on the ID of the source node and an identifier of the first port, so that when receiving a response packet of the first packet, the intermediate node may determine a sending port of the response packet based on the first mapping relationship.

Abstract: Described are transdermal drug delivery compositions comprising amphetamine, methods of making them and therapeutic methods using them. The compositions are provided in a flexible, finite form (e.g. “patch”-type systems) and comprise a polymer matrix that includes amphetamine and an acrylic block copolymer.
