Abstract

The object of study is to verify the distributions of response packets of 3 portal sites such as Naver, Daum, Nate. The period of experiments is from May 19th 2010 to November 7th 2012 and the number of experiments is 4,642. The distributions of Naver, Nate are biomodals. The distribution of Daum has long right tails. 3 distributions are different under 1% significance level using chi-square test and two sample Kolmogorov-Smirnov test. From proportions and percentiles, Naver has a distribution with the largest values. Nate is the second place, and Daum has a distribution with the smallest values. We must make portal pages light to increase response speed including other technologies. We expect our results to activate competition among portal sites.

연구의 목적은 대한민국 주요 3개 포털사이트의 응답패킷 분포를 연구하는 것이다. 대상은 Naver, Daum, Nate 등 포털사이트의 대표페이지이며, 실험기간은 2010년 5월 19일에서 2012년 11월 7일까지이며, 실험횟수는 4,642회 실시하였다. 분포 형태는 응답패킷의 양이 많은 Naver, Nate는 양봉분포를 이루고 있으며, Daum은 오른쪽 꼬리가 긴 분포를 이루고 있다. 분포가 동일한가에 대한 검정은 카이제곱 검정, 이표본 콜모고로프-스미르노프 검정을 통하여 3개 포털의 분포가 유의수준 1%하에서 다르다는 사실을 밝혔다. 상대도수와 백분위 수의 비교를 통해 응답패킷의 분포를 비교하였다. 그 결과 응답패킷의 분포가 Naver가 가장 큰 값을 가졌으며, 다음은 Nate이었으며, Daum은 가장 작은 값을 가졌다. 응답속도를 높이기 위해서는 네트워크 속도를 높이는 것과 병행하여 페이지를 가볍게 만들어야 한다. 본 논문은 포털들이 페이지를 가볍게 만들게 하는 경쟁을 활성화하는데 기여하기를 기대한다.
