3GPP LTE移动的网络架构的云化趋势和联合云基础设施的出现要求替代的服务交付策略，以改善用户体验和有效的资源利用。我们提出了Follow-Me Cloud（FMC），这是一种针对这种环境量身定制的设计，但具有更广泛的适用性，它允许移动的用户始终通过最佳数据锚和移动网关进行连接，而基于云的服务则遵循它们，并通过云基础设施内的最佳服务点进行交付。Follow-Me Cloud采用基于马尔可夫决策过程的算法进行成本效益高的性能优化服务迁移决策，同时提出了两种替代方案，以确保服务的连续性和无中断运行，基于软件定义的网络技术或定位器/标识符分离协议。从我们的分析模型的数值结果跟我来云，以及我们已经开发的两个替代的跟我来云实现的测试台实验，定量和定性地证明了它可以带来的优势。
The trend towards the cloudification of the 3GPP LTE mobile network architecture and the emergence of federated cloud infrastructures call for alternative service delivery strategies for improved user experience and efficient resource utilization. We propose Follow-Me Cloud (FMC), a design tailored to this environment, but with a broader applicability, which allows mobile users to always be connected via the optimal data anchor and mobility gateways, while cloud-based services follow them and are delivered via the optimal service point inside the cloud infrastructure. Follow-Me Cloud applies a Markov-decision-process-based algorithm for cost-effective performance-optimized service migration decisions, while two alternative schemes to ensure service continuity and disruption-free operation are proposed, based on either software defined networking technologies or the locator/identifier separation protocol. Numerical results from our analytic model for follow-me cloud, as well as testbed experiments with the two alternative follow-me cloud implementations we have developed, demonstrate quantitatively and qualitatively the advantages it can bring about.
