Abstract

The advances in networking technology and importance of multimedia communication require real time transaction. In many applications, high reliable real-time communications are required more frequently. In this paper, we propose a reliable communication in cube-based multi -computer using the safety vector. Each node in a cube-based n dimensional multi-computer is associated with a safety vector of n bits, which is an approximated measure of the number and distribution of faults in the neighborhood. We propose an algorithm that can establish detour paths using the safety vector. The established detour paths are disjoint with the primary real-time channel. Therefore, our algorithm is more efficient than earlier proposed algorithms.

네트워크 분야와 멀티미디어 기술의 발전에 따라 실시간 처리에 대한 연구가 각광을 받고 있다. 또한, 많은 용용 분야에서 신뢰도가 높은 실시간 통신에 대한 필요성이 대두되고 있다. 이 논문에서는 큐브 구조를 갖는 다중 컴퓨터에 대한 실시간 통신 알고리즘을 벡터를 이용하여 구현하려고 한다. 큐브 형태의 n 차원 다중 컴퓨터에서 n 개의 안전 벡터는 이웃한 노드들의 결함의 분포와 근사적인 결함의 척도와 관련되어 있다. 이 연구에서는 실시간 채널에서 서로 설정하는 다른 우회 경로를 찾는 알고리즘을 개발한다. 개발한 알고리즘과 기존의 방법들을 비교하여 성능을 분석한다. 시뮬레이션 결과는 이미 제안된 알고리즘과 비교하여 보다 효율적임을 보이고 있다.
