云服务是互联网服务的发展趋势。高性能的数据中心是为全球用户实现实时服务的关键。对于全球旅行的用户来说，云数据中心之间的数据移动性对于提供质量保证的云服务至关重要。然而，现有的传输协议，如TCP，不支持长距离网络上的高速和高吞吐量传输。传统TCP缺乏在远程数据中心之间有效传输数据的能力。在本文中，提出了一种自适应的快速TCP，以更快地在云服务的数据中心之间移动数据。该方法通过调整快速TCP连接的运行参数来提高TCP连接的吞吐量和快速性。仿真结果表明，该算法的吞吐量提高了2.5倍，并且流量控制的快速响应消除了数据包丢失。更好的数据移动性有助于云中移动用户的服务质量。
Cloud service is a trend of promising services on Internet. Data centers with high performance are the key to realize real-time services for worldwide users. For the users travelling in global, data mobility between cloud data centers is essential to offer quality-ensured cloud services. However, existing transmission protocols such as TCP, do not support high speed and high throughput transmission on long-distance networks. Legacy TCP lacks of the ability to efficiently transport data between distant data centers. In this paper, an adaptive Fast TCP is proposed to move data faster between data centers of cloud services. The proposed approach adapts the operational parameter of Fast TCP connections to improve the throughput and the rapidness of TCP connections. Numeric results show that the throughput is improved by 2.5 times and the rapid response of flow control eliminates packet loss. The better data mobility contributes the service quality of travelling users in clouds.
