A distributed bandwidth assignment method for large file transfer with time constraints

As growing the size of digital contents, it is harder to predict the completion time of file transfer. This is an important problem particularly in a data migration at cloud computing. Therefore, some bandwidth assignment methods have been proposed in a model where a transfer request either must be completed by a specified deadline or must be rejected if the deadline cannot be satisfied. However, existing methods are not practical in a large scale network since they assume a centralized control. To overcome this problem, in this paper, we propose a distributed bandwidth assignment method without using global network information. Simulation results show that the proposed method achieves almost equal call-blocking probability to the existing centralized control method.
