Abstract: An NDN and IP fusion network content control method and apparatus. The method comprises: obtaining a request packet issued by a client in a TCP/IP network; performing application layer protocol deep packet analysis on the request packet; upon determining that the request packet is a request packet which satisfies a first type target site, determining a replacement content name according to a pre-established name mapping table; according to the replacement content name and request content of the request packet in the TCP/IP network, generating an interest packet in an NDN protocol format, and forwarding to an NDN network; obtaining a data packet in the NDN protocol format returned after the interest packet in the NDN protocol format was forwarded to the NDN network; converting the data packet in the NDN protocol format into a data packet in an IP protocol format, and returning to the client in the TCP/IP network.

Abstract: The present invention pertains to the field of rice genetic engineering. Specifically, the present invention relates to a rice OsNHAD gene that enhances tolerance to salt stress, which was obtained through gene isolation, cloning and function verification, and also to use of the gene in genetic improvement of salt tolerance of rice. Said gene is selected from one of the following nucleotide sequences: 1) the nucleotide sequence from positions 60 to 1649 of SEQ NO: 1 in the Sequence Listing; or 2) a nucleotide sequence that encodes the same protein as that encoded by 1). Transgenic rice plants obtained by introducing into rice the nucleotide sequence comprising OsNHAD gene operably ligated with exogenous promoter had enhanced salt tolerance.
