Abstract (in Japanese) (See Japanese page) 
(in English) Cache technologies (e.g., P2P, CDN, web proxy, and ICN/CCN) are used for file duplication and load balancing in a file delivery system. In the system, The service latency as a time of delivering files to users is very important to user satisfaction. The optimal scheduling of file delivery that minimizes the latency in a one-link model has already been proposed, and we have also studied the scheduling with fixed file sizes in a two-link model. In this paper, we, therefore, discuss file delivery scheduling with various file sizes in a two-link model. We analyzed the main condition that causes the derivation of scheduling to be NP-complete, then we proposed two approximation algorithms of minimizing and maximizing that condition. Finally, we evaluated our proposed algorithms by a simulation. We showed the algorithm efficiency by using the approximation rate with the optimal solution.
