The invention discloses a dynamic bandwidth allocation algorithm applied to an OFDM-PON (Orthogonal Frequency Division Multiplexing-Passive Optical Network) system and belongs to optical fiber communication systems. The invention utilizes an interruption application response method to realize the bandwidth request and allocation; a plurality of subcarriers in the system are divided into three parts, namely, a communication channel control part, an ONU (Optical Network Unit) default bandwidth part and a part stored in a dynamic pool; when the load on the link is light, each ONU compares respective local flow with local threshold value so as to decide whether an interruption application for extra bandwidth is started; and when the load on the link is heavy, an OLT (Optical Line Terminal) allocates the surplus subcarriers based on the requiring ratio of the ONUs under the condition that the rated bandwidth of the ONUs is met firstly, so as to realize dynamic allocation. The invention ensures low time delay and low package loss rate of a high priority service, also performs bandwidth allocation as required, and can meet the equal allocation between the ONUs and the equal-level priority service when the load of link service flow is heavy.

The invention discloses a blockchain system based on Beidou RDSS (Radio Determination Satellite Service) and an implementation method thereof. The system comprises a plurality of Beidou RDSS terminalsconnected with a blockchain node, and a Beidou satellite. When a packaging node generates a block, the complete block is broadcasted through the Internet, and is transmitted to the Beidou satellite via the packaging node through the Beidou RDSS terminals. After the Beidou satellite receives the data, the Beidou satellite broadcast the block head to other nodes at the superframe format; the BeidouRDSS terminals of other nodes resolve the block head and the precise time of broadcasting, and record the Beidou broadcast time in the TimeStamp field of a new block structure, thereby obtaining theBeidou block head. According to the invention, the system can broadcast the abstract information of the block through the Beidou RDSS, and solves the above problems in a conventional blockchain systemthrough the characteristic that the Beidou satellite can provide a clock with the high time service precision.
