Path characteristics of SCI topological structure in avionics system

Quantitative evaluation index of interconnection in Scalable Coherent Interface (SCI) network is proposed. The interconnection performance algorithm using connectivity matrix is established for four types of network topology. The characteristics of SCI network communication are obtained by calculating the shortest path matrix and the path quantity matrix. For the situations of the nodedamage and edge-damage, the property of anti-corruption is studied. The load distribution of different topology types of SCI network are studied by using Warshall-Floyd path-searching algorithm and Monte-Carlo statistical method. The optimization method of load distribution is obtained by leading in cost functions. The conclusions can be used on the valuation and determination of SCI topological type at the earlier design stage.
