Abstract

Servers are an important part of internet usage. Server is used as the core of browsing on the internet. Various types of application content are created and can only be accessed through the server, regardless of where the server is located. The concept of access where the user has to access the server directly is called the conventional method. Access speed and latency problems occur when users access the server from an application using conventional methods. Access speed and latency at each location will differ depending on the distance between the server and the user, the farther the user is from the server, the slower the access speed and the higher the latency. When the server serves many users, the server will experience overload. From the problems of access speed, latency and access load on the server, we need a system that can cut the distance between the user and the server and share the access load on the server. A CDN (Content Delivery Network) system can distribute content on a server to users at a closer distance. The CDN system is composed of several CDN servers that are located closer to the user so as to maximize speed and minimize latency. In this study, we compare the CDN system with conventional methods, both of which use the LC (Least Connection) algorithm for load sharing on the server that is simulated on the NS-3 application. The performance of this study was measured based on the output parameters of delay, packet loss, throughput and jitter. The results showed that the CDN system had a better output parameter value than conventional at a package size of 10 MB. The results of the comparison of throughput values in the CDN system increased 68.22% compared to conventional, while packet loss decreased by 65.70%, delay decreased by 73.68% and jitter decreased by 42.85% from conventional. Keywords: CDN (Content Delivery Network), LC (Least Connection), NS-3, Server, QoS.
