NDN blockchain network topology performance analysis and optimization model
In order to further improve the network layer transmission performance of the blockchain system based on named data networking(NDN),a performance analysis and optimization model for the NDN blockchain network topol-ogy was proposed.The model included methods for calculating block synchronization time and block transmission re-dundancy in the NDN blockchain system,a network topology scoring system based on block synchronization time and block transmission redundancy,and an optimization scheme based on network topology attributes and scores.The model addressed the incompatibility of blockchain network topology evaluation models based on TCP/IP with NDN block-chain.Given the known network environment parameters and NDN network layer data synchronization methods,the per-formance metrics were calculated and analyzed,providing optimization solutions for actual NDN blockchain network-ing.The experimental results show that after analyzing and optimizing a 9-node network topology using this model,the optimized network topology reduces block synchronization time from 2.95 seconds to 2.37 seconds,a decrease of 19.66%,while maintaining the block transmission redundancy unchanged,and increases the score from 0.64 to 0.82.This demonstrates that the model has a good effect on improving the performance of NDN blockchain.
