摘要： This application provides a network verification method and an apparatus. The method includes: A network verification system obtains configuration data of a plurality of network devices, where a data model of the configuration data is described by using a general data modeling language independent of the network devices; and the network verification system verifies data links between the plurality of network devices based on the configuration data of the plurality of network devices and a topology structure between the plurality of network devices. In the foregoing method, the network verification system verifies the data links between the plurality of network devices based on the topology structure between the plurality of network devices and the configuration data described by using the general data modeling language independent of the network devices. This helps improve scalability of the network verification system, and avoids relatively poor scalability of network simulation software that occurs when conventional network simulation software provides a template for configuration data of each type of network device.

摘要： This application discloses a rate matching method. The method includes: obtaining an encoded bit sequence, where the encoded bit sequence includes g equal-length groups, a quantity of encoded bits in each group is N/g, N is a mother code length of a polar code, N is an integral power of 2, g is an integer greater than or equal to 4 and less than N, and g is an integral power of 2; determining, based on the groups, a position of a bit that needs to be punctured/shortened in the encoded bit sequence; and obtaining an encoded bit in the encoded bit sequence except the bit that needs to be punctured/shortened, to obtain an encoded bit sequence obtained after rate matching. Group-based puncturing/shortening rate matching is easy to implement, thereby improving polar code performance.
