Module 1: Converged Network Connectivity Requirements Lesson 1. 2: Describing Converged Network Requirements © 2006 Cisco Systems, Inc. All rights reserved.

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

Traditional Hierarchical Model © 2006 Cisco Systems, Inc. All rights reserved.

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

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

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

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

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

Phases of IIN § Three phases in building an IIN are: Integrate transport Integrate services Integrate applications © 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. © 2006 Cisco Systems, Inc.

Cisco SONA Layers © 2006 Cisco Systems, Inc. All rights reserved.

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

SONA—Interactive Services Layer Interactive services includes: § voice and collaboration services § mobility services § security and identity services § storage services § computer services © 2006 Cisco Systems, Inc. All rights reserved. § application networking services § network infrastructure virtualization § services management § adaptive management services

SONA—Application Layer includes: § business applications § collaboration applications © 2006 Cisco Systems, Inc. All rights reserved.

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

Summary § 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. © 2006 Cisco Systems, Inc.
