BUFFER ASSIGNMENT SYSTEM OF DATA EXCHANGE NETWORK

PURPOSE:To prevent an excessive delay time even for an equipment severe in time condition such as a line exchange terminal by supervising the number of buffers in use for each transmission/reception information at a prescribed period for each communication party so as not exceed a restricted value for each communication party. CONSTITUTION:When reception information from a line exchange terminal equipment 12 and a packet exchange terminal equipment 13 is received, a data storage section 21 extracts an idle buffer from a reception buffer pool 22 and stores the information. Counters CT1, CT2 of a reception restriction control circuit 24 count respectively a buffer number Nc used for the information of the terminal equipment 12 and a buffer number Np used for the information of the terminal equipment 13 and gives the counts nc, np per unit time to comparators CP1, CP2. A processing unit 15 sets restricted buffer numbers mc, mp based on the processing number to a reception queue 14 sequentially. In case of nc
