Abstract: The application relates to controlling access in a software-defined network (SDN). A controller in the SDN receives an access request from an application program. The controller determines whether an operation on a resource as specified in the access request belongs to a permission list corresponding to the application program. The permission list includes a list of permitted operations on the resource by the application program. When the operation as specified in the access request belongs to the permission list, the controller sends a reply message allowing access by the application program. In this way, accesses by the application program are restricted according to the permission list, and malicious attacks from the application program can be prevented to ensure network security.

Abstract: A detection apparatus concurrently connected to N optical module cages by using N paths. The apparatus accesses a conflict register, acquires an occupancy status of the N paths according to a value of the conflict register, then performs a concurrent probe on M optical module cages connected to M paths that are in the N paths and whose occupancy status are not occupied by system software, to obtain a probe result, where the probe result includes availability information of optical modules of the M optical module cages and a type of the optical modules, and finally, writes the probe result into an availability register, so that the system software can acquire the probe result from the availability register. Therefore, whether an optical module is available in an optical module cage can be monitored in real time and fast insertion and removal operations on the optical module can be sensed.

Abstract: The present invention discloses a terminal access method and an apparatus, to resolve a problem in an existing SCMA multi-terminal access mechanism that a conflict causes system performance degradation and may cause system retransmission. The method is as follows: determining, by a terminal, to enter a contention-based access phase; and determining, by the terminal during each transmission of binary data, a first signature according to a random number seed and a signature matrix, and mapping, according to the first signature, the binary data to a multi-dimensional symbol for transmission, where first signatures used during different transmissions of binary data are different.
