Abstract

In this paper, wireless internet proxy server clusters are used for the wireless internet because their caching, distillation, and clustering functions are helpful to overcome the limitations and needs of the wireless internet. TranSend was proposed as a clustering based wireless internet proxy server but it has disadvantages; 1) its scalability is difficult to achieve because there is no systematic way to do it and 2) its structure is complex because of the inefficient communication structure among modules. In our former research, we proposed the CD-A structure which can be scalable in a systematic way but it also has disadvantages; its communication structure among modules is partly complex. In this paper, we proposed a consolidated scheme which has a systematic scalability and an efficient communication structure among modules. We performed experiments using 16 PCs and experimental results show 196% and 40% performance improvement of the proposed system compared to the TranSend and the CD-A system, respectively.

본 논문에서는 무선 인터넷 프록시 서버 클러스터를 사용하여 무선 인터넷의 문제와 요구들을 캐싱(Caching), 압축(Distillation) 및 클러스터(Clustering)를 통하여 해결하려고 한다. TranSend는 클러스터링 기반의 무선 인터넷 프록시 서버로 제안된 것이나 시스템적인(Systematic) 방법으로 확장성을 보장하지 못하고 모듈간의 불필요한 통신구조로 인해 복잡하다는 단점을 가진다. 본 연구자들은 기존 연구에서 시스템적인 방법으로 확장성을 보장하는 CD-A라는 구조를 제안하였으나 이 역시 모듈간의 부분적으로 불필요한 통신 구조를 가진다는 단점을 가지고 있다. 이에 본 논문에서는 시스템적인 확장성과 단순한 구조를 가지는 클러스터링 기반의 통합형 무선 인터넷 프록시 서버를 제안한다. 16대의 컴퓨터를 사용하여 실험을 수행하였고 실험 결과 TranSend 시스템과 CD-A 시스템에 비해 각각 196%, 40%의 성능 향상을 보였다.
