摘要
为了避免并发传输时网络拥塞,提出基于自适应网络编码的Web数据库并发传输控制方法.分组处理Web数据库中用户需求数据,结合Web通信网络实时丢包率,应用自适应网络编码算法编码分组后的数据,为分组后数据包分配不同码率;经发送端路径缓存模块缓存后,依据码率通过Web通信网络将缓存后的数据包以多路径传输的方式,传输至接收端路径缓存模块对数据包进行缓存;经解码器的数据解码操作后,重组解码数据并将其传输至用户终端,完成Web数据库并发传输控制.实验结果表明:该方法可以实现Web数据库中数据的并发传输控制,为各传输路径合理分配数据量,避免了网络拥堵影响传输效果;并发传输控制后数据可解码率为90%以上,满足了用户高质量数据需求.
Abstract
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.
