摘要： Embodiments of the present application provide a label switching path calculation method and a label switching path calculation device. In the method, by performing hierarchical level and domain value planning on a node in a network in advance, when an LSP is calculated, hierarchical domain information about each node is acquired, and the LSP is calculated using the acquired hierarchical domain information about each node. Since the hierarchical domain information about each node designates a network position where the node is located, it can be avoided that an LSP obtained by calculation reroutes an access layer according to the hierarchical domain information about each node and a satisfaction criterion for the LSP during the LSP calculation process. In addition, the technical solution provided in the embodiments of the present application needs no manual intervention in the whole LSP calculation process, realizing the automatic calculation of an LSP.

摘要： A WLAN baseband chip and an FDMA PPDU generation method are disclosed. The WLAN baseband chip obtains a subcarrier coefficient corresponding to a subcarrier set, m LDR SYNC sequences, and n−m HDR SYNC sequences. The WLAN baseband chip performs duplicating processing on m data streams in n data streams, to obtain m data sequences on which the duplicating processing has been performed and n−m remaining data streams. The WLAN baseband chip obtains m pieces of to-be-modulated data based on the m LDR SYNC sequences and the m data sequences on which the duplicating processing has been performed, and obtains n−m pieces of to-be-modulated data based on the n−m HDR SYNC sequences and the n−m remaining data streams, to obtain n pieces of to-be-modulated data. The WLAN baseband chip performs postprocessing to obtain a frequency-domain symbol sequence, to obtain an FDMA PPDU.
