| Abstract(in English) | Users can now connect to the Internet through a wide variety of access networks and communication terminals. This has brought a great demand for cloud computing which allows users to enjoy various Internet services provided by data centers (DC) anytime, anywhere. In cloud computing, the problem arises that a user’s quality of service is unfair among users who are different distances from DCs. To provide fair communication service to each user, we previously proposed a bandwidth allocation scheme based on collectable information in DC networksand showed the effectiveness of this approach in a case where bottleneck links exist in DC networks. However, if bottleneck links exist outside DC networks, the link utilization in DC networks will be degraded. In this study, we propose a bandwidth allocation scheme based on collectable information to improve fairness and link utilization in DC networks. This scheme collects flow information including the transmission rate of each user in addition to the information considered in the previous work, and then fairly allocates transmission rate to each user based on the collected information in DC networks. Through simulation evaluations, we showed that the proposed scheme achieves high fairness and link utilization even when bottleneck link exists outside DC networks. |
