Abstract

The number and size of resource constituting the web page has been increasing steadily, and this circumstance leads to rapidly falling quality of web service in mobile network that offer relatively higher delay. Moreover, Improving the quality of a web services protocol is difficult to provide network function because the current network architecture has closed structure. In this paper, we suggest schemes to enhance web performance in mobile network, which are Check Coded DOM scheme and Functional JavaScript Transmission scheme, and then try to seek idea which can be provided suggested schemes as a network function using NFV(Network Function Virtualization). For the performance evaluation and analysis about the suggested schemes, we perform network simulation using SMPL library. We confirm that suggested schemes offer better performance in term of page loading time, the number of message and the amount of traffic in the network than HTTP Protocol.

웹 페이지를 구성하는 리소소의 개수와 크기가 점점 증가하고 있으며, 이는 상대적으로 지연이 큰 모바일 네트워크에서 웹 서비스의 급격한 품질 저하로 이어지고 있다. 게다가 현재의 네트워크 구조는 폐쇄적인 구조를 가지고 있기 때문에 웹 서비스의 품질을 향상시키는 프로토콜을 개발할지라도 네트워크 기능으로 제공하기 어렵다는 문제가 있다. 본 논문에서는 모바일 네트워크에서 웹 성능을 향상시키기 위한 2가지 방안으로 Check Coded DOM 방안과 Functional JavaScript 전송 방안을 제안하고, NFV(Network Function Virtualization)를 활용하여 제안 방안이 네트워크 기능으로 제공될 수 있는 방안 모색 해본다. SMPL 라이브러리를 이용한 네트워크 시뮬레이션을 통해서 제안 방안의 성능을 평가하고 분석했으며, 제안 방안이 기존 HTTP 프로토콜보다 페이지 로딩 시간, 네트워크에 발생하는 메시지의 개수, 네트워크에 발생하는 트래픽 측면에서 향상된 성능을 제공함을 확인 할 수 있었다.
