The OSI RM computer network architecture delineates the basic functionality and services are offered by all seven layers of OSI RM to be interlinking heterogeneous computer systems toward accomplishing useful communication among several application procedures. The emplacement of authentication, confidentiality, traffic flow confidentiality, accessibility, unity, and non-repudiation protection services and several security mechanisms. In the OSI (Open Systems Interconnection) RM (Reference Model) have seven layer in computer network architecture is a polemically issue. In this paper, the several issues growing in the emplacement of traffic flow confidentiality service, traffic padding, encipherment, and routing controller security mechanisms in the OSI RM computer network architecture are presented.
