Large File Transmission in Network-Coded Networks with Packet Loss - A Performance Perspective
Network coding can significantly improve the transmission rate of communication networks with packet loss compared with routing. But using network coding usually involves more computational and storage costs in network devices and terminals. The authors discuss some recent schemes for file transmission in networks employing coding and compare the computational and storage costs of these schemes. The up-to-date state is that network coding is nearly ready for practical applications in large file transmission. Data packets transmitted in a communication network can be erased due to channel noise, congestion, faulty network hardware, and so on.
