Web Database Concurrent Transmission Control Method Based on Adaptive Network Coding
To avoid network congestion during concurrent transmission,a Web database concurrent trans-mission control method based on adaptive network encoding is proposed.Group processing of user demand data in Web databases,combined with the real-time packet loss rate of Web communication networks,applying adaptive network coding algorithms to encode the grouped data,and assigning different bit rates to the grouped data packets.After being cached by the path caching module at the sending end,the cached data packets are transmitted through a Web communication network using a multipath transmission method based on the bit rate,and then transmitted to the path caching module at the receiving end for caching the data packets.After the data decoding operation of the decoder,the decoded data is recom-bined and transmitted to the user terminal to complete the concurrent transmission control of the Web database.The experimental results show that this method can achieve concurrent transmission control of data in Web databases,allocate data volume reasonably for each transmission path,and avoid network congestion affecting transmission efficiency.After concurrent transmission control,the data decoding rate is over 90%,meeting the high-quality data needs of users.
