摘要:
随着5G网络即将到来，互联网设备、无线网络流量和基地台数量都将会增加，基地台的架设密度将会变得密集。5G网络的速度更快，传输也会变得拥挤，若可以在基地台里面暂时存放常被存取到的资料，即可减少回程的负载，但基地台里的快取空间有限，不太可能容纳得下所有装置可能会请求的资料，如何在有限的空间摆放快取资料提升装置请求资料的命中率成为一个重要的议题。许多诸如Facebook的动态网络资料随时间而存取不同的网页，但是网页是由主机决定，许多使用者的Web Part(如广告页)是相同的，在这种情境之下，本研究将进一步探讨如何运用5G边际快取，以提升系统存取效能。
Abstract:
With the arrival of the 5G network, the number of Internet devices, wireless network traffic and base stations will increase, and the density of the base stations will become denser. 5G networks will become faster and the traffic will become congested. If the frequently accessed data can be temporarily stored in the base station, the backhaul load can be reduced, but the cache space in the base station is limited and it is unlikely to accommodate all the information that may be requested by the device. How to place cache data in limited space to enhance the hit rate of data request has become an important issue. The dynamical Web data are changed time by time, but all these data are determined by server hosts. Some Web part, such as advertising pages, might be the same among the users. This study further discusses how to use 5G edge caching to enhance the system access performance
