Objectives
Explain the Cisco conceptual network models, such as Cisco Enterprise Architecture and Cisco hierarchical network model.
Describe the traffic conditions in a converged network.
Describe the IIN and the SONA framework.

Network Traffic Mix and Requirements
Converged network traffic mix:Voice and video traffic
Voice applications traffic
Mission-critical applications traffic
Transactional traffic
Routing update traffic
Network management traffic
Bulk transfer (best-effort) and scavenger (less-than-best-effort) traffic
Key requirements:Performance (bandwidth, delay, and jitter)
Security (access and transmission)

Intelligent Information Network (IIN)
IIN integrates networked resources and information assets.
IIN extends intelligence across multiple products and infrastructure layers.
IIN actively participates in the delivery of services and applications.

Phases of IIN
Three phases in building an IIN are:Integrate transport
Integrate services
Integrate applications

Cisco SONA Framework
Cisco SONA is an architectural framework.
Cisco SONA brings several advantages to enterprises:Outlines how enterprises can evolve toward the IIN
Illustrates how to build integrated systems across a fully converged intelligent network
Improves flexibility and increases efficiency
Cisco provides an extensive product line, services, proven architectures, and experience to help the enterprises achieve their business goals.

SONA—Networked Infrastructure Layer
The goal is “anywhere/anytime connectivity.”

SONA—Interactive Services Layer
voice and collaboration services mobility services security and identity services storage services computer services
application networking services network infrastructure
virtualization services management adaptive management services
Interactive services includes:

SONA—Application Layer
business applications collaboration applications
Application Layer includes:

Self Check
1. What are the 3 building blocks of the hierarchical model?
2. Describe the special needs of voice and video traffic.
3. What types of traffic could be considered best-effort and less-than-best-effort?
4. What is AON?
5. What are the 3 layers of SONA?

The traditional three-layer hierarchical model no longer completely meets the needs of large converged networks carrying voice, video, and data. IIN aligns IT resources with business priorities.
Cisco Enterprise Architecture and SONA provide a framework for deploying converged networks.
Dealing with complex traffic mixes is a key feature of Cisco Enterprise Architecture. The Service layer of SONA addresses the performance and security requirements of converged networks.
IIN aligns IT resources with business priorities.
Cisco SONA provides an evolutionary path to IIN.
