Analysis: Wireless Communication and associated network coding technology

Network encoding is based on the storage and forwarding of network information flows at network relay nodes to improve network throughput and save network bandwidth. In wireless communication networks, network coding, as one of the key technologies, can reduce network resource consumption to a certain extent, improve spectrum resource utilization, and transmit as much data as possible in limited spectrum resources, increase the channel transmission ca

Pre-analysis of Hadoop 3.0 Erasure Coding Erasure code function

ObjectiveHDFs can also support the Erasure coding feature, which will be released in Hadoop 3.0 and can be validated by the diagram:In HDFS-7285, this new feature is implemented. Since this feature is far from the release stage, it is possible that the code behind this block will be further modified, so just do a so-called pre-analysis , Help you get an idea of how the Hadoop community is doing this right now. I have not been exposed to erasure
