Abstract

In this paper, we analyse the effect of redundancy types and non-stop forwarding scheme on network service availability. We use stochastic reward net models as enabling modeling approach for the analytical evaluation. We first design stochastic reward nets for redundancy models with or without non-stop forwarding and then evaluate their availability using Stochastic Petri Net Package.

본 논문에서는 다양한 다중화 모형과 논스톱 포워딩 기능이 네트워크 서비스의 가용도에 미치는 영향을 비교 분석한다. 다중화 모형 중 no redundancy, 2N redundancy, N-way redundancy, N-way active redundancy 모형에 대한 확률적 리워드 네트(Stochastic Reward Net, SRN) 모델을 설계하고, 각각의 모형에 대해 논스톱 포워딩 기능을 추가한 SRN 모델을 설계한다. 확률적 페트리 네트 패키지(Stochastic Petri Net Package, SPNP)를 활용하여 설계한 SRN 모델의 가용도를 구한다.
