Abstract

As a way to overcome the problems that when you transmit data to and receive data from End Device to participate in the GRID network, QoS has not been, GARA supports the Diffserv system basically. However, the problem when it is assumed settings related to the Diffserv between the ISP and the ISP is wrong with each other, that it is not possible to receive a complete QoS services began to appear. In this paper, we tried to overcome these drawbacks, in networks based GARA the (Globus Architecture for Reservation and Allocation), using the SLA (Service Level Agrement) server, was treated in the highest priority to the data, the ISP there is provided a method for setting the Diffserv the ISP is even wrong and, using the TOS of the IP header, to solve this, it is described about the direction of future research.

GARA는 GRID 네트워크에 참여하는 End Device와 데이터를 주고받을 때, QoS가 되지 않는 문제점을 극복한 방법으로써, 기본적으로 Diffserv 방식을 지원한다. 그러나 ISP와 ISP 사이에 Diffserv와 관련된 설정이 서로 틀리게 되어 있다고 가정했을 때, QoS 서비스를 온전히 받을 수 없는 문제점이 나타나게 되었다. 본 논문은 이러한 단점을 극복하고자, GARA(Globus Architecture for Reservation and Allocation)를 기반으로 하는 네트워크에서 SLA(Service Level Agrement) 서버를 사용하여 데이터를 최우선적으로 처리하고, ISP와 ISP의 Diffserv 설정이 다르다 할지라도, IP 헤더의 TOS를 사용하여 이를 해결할 수 있는 방법을 제안하고 추후 연구방향에 대하여 기술하였다.
