论文摘要
股票期权的概念用于解决资源的稀缺性，我们的预测机制先前工具无法充分解决资源。使用预测性预订方案，正在通过给定时间范围内通过良好的技术（内核回归估计器）来监视网络和磁盘资源。接下来，二级市场机制可大大提高我们预测性保留计划的效率和鲁棒性，通过允许在原始服务器（CDN客户端）之间快速交换未使用的（剩余）资源。可以通过实施社会最佳实践或允许在一天结束时或较短的时间间隔进行自动拍卖来实现这种交流。最后，我们进一步增强了我们的预测机制。根据一天结束时缺乏资源，获得并行使股票期权。结果，原始服务器可以以正常价格获取资源（如果需要）。我们机制的有效性进一步提高。
The concept of Stock Options is used to address the scarcity of resources, not adequately addressed by the previous tools of our Prediction Mechanism. Using a Predictive Reservation Scheme, network and disk resources are being monitored through well-established techniques (Kernel Regression Estimators) in a given time frame. Next, an Secondary Market mechanism significantly improves the efficiency and robustness of our Predictive Reservation Scheme by allowing the fast exchange of unused (remaining) resources between the Origin Servers (CDN Clients). This exchange can happen, either by implementing socially optimal practices or by allowing automatic electronic auctions at the end of the day or at shorter time intervals. Finally, we further enhance our Prediction Mechanism; Stock Options are obtained and exercised, depending on the lack of resources at the end of day. As a result, Origin Servers may acquire resources (if required) at a normal price. The effectiveness of our mechanism further improves.
