초록

하이퍼 큐브는 정규적이며 결함 허용 능력을 갖고 있기 때문에 결함 허용 알고리즘을 구현하기 쉽다. 하이퍼 큐브를 이용한 결함 허용 알고리즘들이 많이 개발되었다. 이러한 알고리즘들 중에 안전(safe)과 불안정(unsafe) 개념을 이용한 알고리즘이 Masuyama등에 의해 개발되었다. 이 논문에서는 Masuyama의 알고리즘을 개선한 새로운 알고리즘을 제안하고 시뮬레이션을 통하여 성능을 비교한다.

Hypercube has a capability of fault-tolerance and regularity, which is easy to develop an algorithm. Many algorithms have been developed as an efficient fault-tolerance routing algorithm using hypercube. Among these algorithms, a method which use safe and unsafe concept was developed by Masuyama. Masuyama suggested an enhanced algorithm that take advantage of unsafe-safe concept. In this paper, we propose an algorithm that uses the unsafe, safe concept and modify Masuyama's algorithm. Using simulator we compare the performance of the proposed algorithm with existing algorithms.
