The invention relates to token flow control method and system of surge GNSS (Global Navigation Satellite System) data. The method comprises the following steps of: creating a token flow control management service node between a GNSS data statistic node and a GNSS data application node; reporting respective token flow information of the GNSS data statistic node and the GNSS data application node to the token flow control management service node; searching an idle outflow token flow statistic node and an idle inflow token flow application node by the token flow control management service node according to the received token flow information; sending out a data synchronization flow control instruction from the token flow control management service node to the idle outflow token flow statistic node; and synchronizing data to the corresponding idle inflow token flow application node after the idle outflow token flow statistic node receives the data synchronization flow control instruction. The technical scheme provided by the invention can solve the problem of surge impact of GNSS data.
Description
technical field [0001] The invention belongs to the technical field of network communication and relates to data flow control technology, in particular to a token flow control method and system for surge GNSS data. Background technique [0002] Global Navigation Satellite System (GNSS) technology is more and more applied in the field of communication technology. In the case of a small amount of data processing, data access generally does not cause problems, but if the amount of data accessed at the same time is huge, data surge problems may occur. For example: in a national-level GNSS data application system, the GNSS platforms of each province, through the protocol channel, realize the confluence of all data to the national network joint control platform. How to display a large amount of data on the application software of the national network joint control platform is a very difficult technical problem. Generally speaking, due to the large number of hardware devices confi...
