摘要： A media delivery system includes a media manager (MM) a central server that supports peer to peer (P2P) technology (CS-P), a request routing system that supports P2P technology (RRS-P), and an edge server that supports P2P technology (ES-P) and multiple P2P clients. A method for playing streaming media based on the above media delivery system includes: the MM publishes a live channel notification to the CS-P, RRS-P, and ES-P; the CS-P obtains streaming data packets from a live source and parses and slices the packets to generate slice data; the ES-P obtains the slice data from the CS-P and/or other ES-Ps that are able to provide slice data and caches the slice data; and the P2P client obtains the slice data from the ES-P or other P2P clients and delivers the data, or the data is played by a local player after an assembly operation by the P2P client. With the P2P technology, the present invention improves the prior media delivery network and realizes the playing of streaming media to a large number of clients.

摘要： The present invention relates to network coding and discloses a method, an apparatus, and a system for random linear network coding to prevent the complicated and time-consuming process of network coding. The coding method for random linear network includes: splitting original data into at least two data blocks sequentially; determining at least two coefficient groups, wherein a length of each coefficient group is the same as the number of the data blocks, and the coefficient group comprises two elements; performing a bitwise-AND operation on the data blocks and coefficients corresponding to the data blocks to obtain code blocks; and performing a bitwise-XOR operation between the code blocks to obtain a code packet. The present invention is applicable to the network coding which requires a high efficiency of coding.
