摘要:

随着数十亿设备连接到互联网,将云作为集中式服务器将是不可持续的。未来的方向是将计算从云端分散到更接近用户的网络边缘。这减少了用户设备与云之间的通信延迟,是本文定义的“雾计算”的前提。本文的目的是突出的可行性和好处,提高服务质量和经验,通过使用雾计算。对于一个在线游戏用例,我们发现,与使用纯云模型相比,使用网络边缘时用户的平均响应时间提高了20%。还观察到边缘和云服务器之间的流量减少了90%以上。初步结果突出了雾计算在实现可持续计算模型方面的潜力,并突出了将网络边缘集成到计算生态系统中的好处。

英文摘要:

As billions of devices get connected to the Internet, it will not be sustainable to use the cloud as a centralised server. The way forward is to decentralise computations away from the cloud towards the edge of the network closer to the user. This reduces the latency of communication between a user device and the cloud, and is the premise of 'fog computing' defined in this paper. The aim of this paper is to highlight the feasibility and the benefits in improving the Quality-of-Service and Experience by using fog computing. For an online game use-case, we found that the average response time for a user is improved by 20% when using the edge of the network in comparison to using a cloud-only model. It was also observed that the volume of traffic between the edge and the cloud server is reduced by over 90% for the use-case. The preliminary results highlight the potential of fog computing in achieving a sustainable computing model and highlights the benefits of integrating the edge of the network into the computing ecosystem.
