Network Traffic Mix and Requirements
Converged network traffic mix:Voice and video traffic
Voice applications traffic
Mission-critical applications traffic
Transactional trafficRouting 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 informationassets.
IIN extends intelligence across multiple products and
infrastructure layers.
IIN actively participates in the delivery of services andapplications.

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 fullyconverged intelligent network
Improves flexibility and increases efficiency
Cisco provides an extensive product line, services,
proven architectures, and experience to help theenterprises achieve their business goals.

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

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