4. © 2006 Cisco Systems, Inc. All rights reserved. Cisco Enterprise Architecture

5. © 2006 Cisco Systems, Inc. All rights reserved. Campus Architecture  IP Communications  mobility  advanced security Campus Architecture combines a core infrastructure of intelligent switching and routing including:

6. © 2006 Cisco Systems, Inc. All rights reserved. Data Center Architecture  requirements for consolidation  business continuance  security The Data Center is a cohesive, adaptive network architecture supporting:

7. © 2006 Cisco Systems, Inc. All rights reserved. Branch Architecture  security  IP communications  advanced application performance supporting thousands of remote locations/users The Branch allows enterprises to extend head-office applications and services including:

8. © 2006 Cisco Systems, Inc. All rights reserved. Teleworker Architecture  Teleworker architecture allows enterprises to securely deliver voice and data services to remote, small or home offices.

9. © 2006 Cisco Systems, Inc. All rights reserved. WAN Architecture  WAN architecture offers the convergence of voice, video and data services over a single IP communications network.

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)

13. © 2006 Cisco Systems, Inc. All rights reserved. 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.

14. © 2006 Cisco Systems, Inc. All rights reserved. Phases of IIN  Three phases in building an IIN are: Integrate transport Integrate services Integrate applications

15. © 2006 Cisco Systems, Inc. All rights reserved. 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.

17. © 2006 Cisco Systems, Inc. All rights reserved. SONA—Networked Infrastructure Layer  The goal is “anywhere/anytime connectivity.”

18. © 2006 Cisco Systems, Inc. All rights reserved. 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:

19. © 2006 Cisco Systems, Inc. All rights reserved. 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?

21. © 2006 Cisco Systems, Inc. All rights reserved.  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.
