The endpoint discovery protocol is an important factor affecting the delay performance of DDS middleware. Aiming at the huge problem of endpoint database in the FPGA platform middleware system, this paper proposes a compressed bloom filtering (BF) method, which reduces the space occupied by the stored data by cross-compressing the two sets of data after hash mapping. The simulation results show that the compressed bloom filter (CBF) method can significantly improve the effective capacity under the same misjudgment rate and filter length.
