    Abstract: 有鑑於人們對網路的依賴性與日俱增,且使用者對網路安全的觀念也不斷進步,使用NAT的環境也因此增加,再加上NAT類型不斷推陳出新,使得NAT穿越日益困難。IETF針對多媒體傳輸提出ICE作為防火牆穿越的方法,但因上述原因,導致使用者無法完全透過STUN伺服器以對等式網路建立連線,使得架構中的TURN伺服器負載量上升,過去雖然有相關論文欲解決此問題,但其目標大多著重於提升以STUN伺服器穿越NAT的成功率,因此本論文基於ICE協定,以霧運算架構提出另一負載平衡解決方法,並以SVM模型所得的負載值作為選擇TURN伺服器的依據。我們在論文最後對伺服器最大負載量、不同的分析模型,以及架構中新增的流程所增加的延遲時間進行討論,並得到可以在不改變ICE協定,以及僅增加少量延遲時間的狀況下達成負載平衡。
    In view of the increasing dependence on the Internet and the improvement of users' concept of network security, the environment using NAT has also increased. In addition, the NAT type has been continuously changed, making NAT traversal increasingly difficult. The IETF proposed ICE as a method for firewall traversal for multimedia transmission. However, due to the above reasons, the user could not completely connect with the peer-to-peer network through the STUN server, so that the load of the TURN server increased. Some researchers proposed a few methods to solve this problem, but their goal is mostly focused on improving the success rate of the STUN server traversing NAT. Therefore, based on the ICE protocol, we proposed another load balancing solution based on the fog computing architecture. In the solution, we used the load value obtained by the SVM model as the basis for selecting the TURN server. In experiments, we showed the maximum load on the TURN server and compared the accuracy of the different analysis models. We also discussed the increased latency of the new processes in the architecture. At the end of this paper, we achieved the load balancing without changing the ICE protocol and added only a small amount of latency.
