Networking in the Enterprise Introducing Routing and Switching in the Enterprise – Chapter 1

Objectives Describe the logical architecture and components of an enterprise network Explain the types of applications and traffic flows present on an enterprise network Examine how enterprises integrate remote workers into their networks Define the role and importance of a telecommuter Describe the function and importance of VPNs

Describe an Enterprise Network A large business environment with many users and locations Supported by an enterprise network Provides mission-critical services and applications Requires centralized control: NOC

Describe an Enterprise Network Network infrastructure 99.999% uptime High-end equipment Fail-over capabilities Redundancy

Describe an Enterprise Network Hierarchical design Access, Distribution, Core layers Enterprise networks contain both LAN and WAN technologies

Describe an Enterprise Network Intranet Provide access to local and remote employees Private network Controlled by firewalls Extranet Privileged access for business partners Private network Controlled access

Explain Types of Applications and Traffic Flows within an Enterprise Network Local WAN External Optimized bandwidth Security

Explain Types of Applications and Traffic Flows within an Enterprise Network Characteristics of different types of network traffic Network traffic prioritization Classification Pre-queuing Queuing and scheduling Post-queuing

Explain Types of Applications and Traffic Flows within an Enterprise Network Factors affecting enterprise traffic Latency Jitter Quality of Service (QoS)

Examine How Enterprises Integrate Remote Workers into their Networks Teleworking Telecommuting Teleconferencing

Examine How Enterprises Integrate Remote Workers into their Networks Describe remote worker applications VoIP Sharing applications FTP and Telnet

Examine How Enterprises Integrate Remote Workers into their Networks Function and importance of VPNs Encryption of traffic Tunnels Client/server application

Summary Enterprise networks support mission critical services and traffic Enterprise design includes a campus, enterprise edge, and service provider edge Intranets and extranets are private networks designed for specific access privileges VPNs create encrypted tunnels for use by teleworkers
