Abstract

In this paper, a dynamic route control scheme to increase speed of data communication over public network is presented. And a new structure of gateway which is suitable for the public network environments is proposed and analyzed. For dynamic allocation of transmission routing resources of the gateway and improvement of call processing ratio of the system, virtual queue is used. As results, route utilization ratio of the proposed scheme can be improved up to 60% as compared to the conventional fixed route control scheme. For the case of limited number of routes, it provides high speed data communication while maintaining delay time as low as possible. In addition, as the allocation period at call access node can be varied with the traffic in the proposed scheme, various traffics can be applied easily. Thus, it can be expected that the presented dynamic route control gateway may be suitable for application in high speed data communication over public network.

본 논문에서는 공중망 게이트웨이에서 데이터통신의 전송속도를 증가시키기 위한 동적경로제어방식이 제시된다. 그리고 공중망 환경에 적합한 게이트웨이의 새로운 구조를 제안하고 분석한다. 여기서는 게이트웨이 전송경로자원의 효율적인 동적할당과 시스템 호 처리율의 향상을 위하여 가상 큐를 사용하였다. 그 결과, 기존의 고정경로제어에 비하여 제안된 방식은 최대 60%까지 향상된 경로이용율을 나타내었다. 특히 발생 트래픽이 한정된 경우 이 방식은 최소한의 대기시간을 유지하면서도 고속 데이터통신을 제공할 수 있었다. 뿐만 아니라 제안된 방식에서는 트래픽에 따라 호 접속망의 할당주기가 변화되므로 다양한 트래픽이 쉽게 적용된다. 따라서 제안된 동적경로제어에 의한 게이트웨이는 공중망에서의 고속 데이터통신의 응용에 적합할 것으로 사료된다.
