traffic, including data, voice, and video, are
consolidated onto an IP network for secure network convergence.
By integrating data, voice, and video transport into a single,
standards-based, modular network, organizations can simplify
network management and generate enterprise-wide efficiencies.
Network convergence also lays the foundation for a new class of
IP-enabled applications delivered through Cisco IP
Communications solutions. Phase 2: Integrated
services
With a converged network infrastructure, IT
resources can be pooled and shared or “virtualized” to flexibly
address the changing needs of the organization. Integrated
services help to unify common elements, such as storage and
data center server capacity. By extending virtualization
capabilities to encompass server, storage, and network
elements, an organization can transparently use all its
resources more efficiently. Business continuity is also
enhanced because shared resources across the IIN provide
services in the event of a local system failure.
Phase 3: Integrated applications
With
Application-Oriented Networking (AON) technology, Cisco has
entered the third phase of building the IIN, which focuses on
making the network “application-aware” so that it can optimize
application performance and deliver networked applications to
users more efficiently. In addition to capabilities such as
content caching, load balancing, and application-level
security, Cisco AON makes it possible for the network to
simplify the application infrastructure by integrating
intelligent application message handling, optimization, and
security into the existing network. Web

1.1.4 The SONA Framework The Cisco SONA framework
outlines how enterprises can evolve to an IIN. Cisco SONA
leverages Cisco and Cisco partner solutions, services, and
experience working with enterprises across industries to
deliver proven, scalable business solutions to help enterprises
achieve their business goals. It addresses new IT challenges,
such as the deployment of service-oriented architectures (SOA),
Web services, and virtualization. The Cisco SONA framework
provides the following advantages: - Outlines the path
toward the IIN
- Illustrates how to build integrated
systems across a fully converged IIN
- Improves
flexibility and increases efficiency, which results in
optimized applications, processes, and resources
The
Cisco SONA framework shows how integrated systems can allow a
dynamic, flexible architecture, and provide for operational
efficiency through standardization and virtualization. It
brings forth the notion that the network is the common element
that connects and enables all components of the IT
infrastructure. Cisco SONA outlines these three layers of the
IIN: and - Network infrastructure layer:
Interconnects all IT resources across a converged network
foundation. The IT resources include servers, storage, and
clients. The network infrastructure layer represents how these
resources exist in different places in the network, including
the campus, branch, data center, WAN and Metropolitan Area
Network (MAN), and teleworker. The objective for customers in
this layer is to have anywhere and anytime connectivity.
- Interactive services layer: Enables efficient
allocation of resources to applications and business processes
that are delivered through the networked infrastructure. This
layer comprises these services:
- Voice and
collaboration
- Mobility
- Security and
identity
- Storage
- Computer
-
Application networking
- Network infrastructure
virtualization
- Services management
- Adaptive
management
- Application layer: Includes
business applications and collaboration applications. The
objective for customers in this layer is to meet business
requirements and achieve efficiencies by leveraging the
interactive services layer.

Cisco Enterprise Architectures Based on the Cisco SONA
framework, Cisco Enterprise Architecture helps organizations
evolve to an IIN. The architecture fully integrates and
optimizes the networked infrastructure, interactive services,
and applications across entire enterprises. The architectures
specifically target campus, data center, branch, teleworker,
MAN and WAN locations. Campus Architecture
The
Cisco Enterprise campus architecture combines a core
infrastructure of intelligent switching and routing with
tightly integrated productivity-enhancing technologies,
including IP Communications, mobility, and advanced security.
The architecture provides the enterprise with high availability
through a resilient multilayer design, redundant hardware and
software features, and automatic procedures for reconfiguring
network paths when failures occur. Multicast provides optimized
bandwidth consumption, and quality of service (QoS) prevents
oversubscription to ensure that real-time traffic, such as
voice and video or critical data, is not dropped or delayed.
Integrated security protects against and mitigates the impact
of worms, viruses, and other attacks on the network, even at
the port level. Cisco enterprise-wide architecture extends
