Network Conceptual Models
Conceptual models allow network designers to move from looking at the
network as a collection of devices to viewing it as a way to provide services
to users, no matter where the users and the services are located. Cisco
currently defines three models as the building blocks of a world-class enterprise
network: the Intelligent Information Network, the Service-Oriented
Network Architecture, and the Cisco Enterprise Architecture.
Intelligent Information Network
The Intelligent Information Network (IIN) seeks to create a holistic network
that integrates with and enables your business processes. It allows centralized
control and interoperation of distributed systems. This control and interoperability
can provide increased network security and efficiency.
The IIN consists of three components:
�¡ Integrated transport.Data, voice, and video all transported over a
secure IP network.
�¡ Integrated services.Shared/virtualized resources, such as storage
and servers.
�¡ Integrated applications.The network is application aware, enhancing
the efficiency of applications. This component includes
Application-Oriented Networking (AON), which offloads shared,
common functions, such as logging and security, to the network.
