Abstract(in English) In λ-grid networks, data files are stored on replica servers as replica files, and computing servers download those replica files in parallel. As a result, we can use λ-grid networks efficiently. One of problems in λ-grid networks is wavelength contention which occurs when files are transmitted. To resolve this problem, we have proposed a file allocation method with network coding, which allocates encoding data to replica servers. Thus the scheme can allocate replica files to many servers, and computing servers efficiently perform parallel downloading which reduces wavelength contention. In the past, we have showed the basic operation and performance of the scheme, but we have not mentioned how to encode and allocate data dynamically. In this paper, we propose such a dynamic encoding and replication scheme, and show the performance of the proposed scheme through simulation experiments.
