Abstract: A system for processing packets in a distributed architecture system includes a main control board, at least one service board, and at least one interface board. The system determines a specified CPU corresponding to a received packet; and, by the service board corresponding to the CPU, processes the received packet. The received packets are processed in the service board corresponding to the specified CPU. Therefore, the packets are evenly distributed to all service boards for being processed, the workload of the main control board is relieved, the service throughput is increased significantly, and the packet processing efficiency of the whole architecture is improved.

Abstract: A method and apparatus for accessing a wireless sensor network are provided in embodiments of this invention. The technical solution provided in embodiments of this invention includes: when receiving a first beacon frame, stopping channel scan temporarily, and establishing a new channel scan sequence according to operating channels of a current wireless sensor network recorded in the beacon frame. Non-operating channels are not included in the new channel scan sequence. Time for performing subsequence channel scan is reduced, so that the process of accessing the current wireless sensor network of a device node expecting for network can be accelerated.
