Abstract

Abstract:

To avionics of fibre channel(FC)interconnection,communication model of fabric that is made up of one or more FC switches is given based on basic FC interconnection model.On task based analysis method of system reliability,the reliability expression of fabric topology is given and the concept of basic path is proposed.To improve system reliability of avionics,two redundancy methods of fabric topology:basic path redundancy and whole fabric redundancy, are proposed.

Key words: communication , network , technology, , reliability, , fibre , channel(FC), , avionics, , fault , tolerance
