Dynamic Communication Protocol for Quick Response in Interactive Communication

Recently, many commercial cloud computing services have rapidly evolved, and it is expected that users will increasingly access these cloud services using mobile devices or thin client devices with response-sensitive applications such as remote desktop. For such communications, the transmission control protocol (TCP) is typically used between such devices and virtual machines in cloud data centers. However, frequent quality changes in the wireless link or movements of virtual machines influence end-to-end TCP sessions, and the communication response may be degraded. In this paper, we propose a method to improve the response in interactive communication by dynamically changing congestion control algorithms based on changes in the link quality. We then show the effectiveness of the proposed method.
