The network model for data communication network has been studied since 1970s [1-2]. Based on those studies, J. Saltzer, in
1993, specified some essential network objects and binding
between them for data communication network [3] and some related works were followed [4]. This paper, based on the existing works, proposes a generic network model for FI, analyzes structural problems of the current Internet, and suggests requirement for FI architecture design. Also, this paper shows how the generic model addresses recent network issues
