Objectives

Explain the Cisco conceptual network models, such asCisco Enterprise Architecture and Cisco hierarchicalnetwork model.

Describe the traffic conditions in a converged network.

Describe the IIN and the SONA framework.

Branch Architecture

security

IP communications

advanced application performance supporting

thousands of remote locations/users

The Branch allows enterprises to extend head-officeapplications and services including:



Teleworker Architecture

Teleworker architecture allows enterprises to securelydeliver voice and data services to remote, small or

home offices.



WAN Architecture

WAN architecture offers the convergence of voice,video and data services over a single IP

communications network.



Example: Enterprise Network



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)



Example: Integrated Services in a ConvergedNetwork



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.



Cisco SONA Layers



SONANetworked Infrastructure Layer

The goal is anywhere/anytime connectivity.



SONAInteractive Services Layer

voice and collaborationservices

mobility services security and identity services

storage services

computer services

application networking services

network infrastructurevirtualization

services management

adaptive management services

Interactive services includes:



SONAApplication Layer

business applications

collaboration applications

Application Layer includes:



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.
