Study Notes

Network Infrastructure Information

Network infrastructure information includes locations and types of servers and network devices, size of each site, data center and closet locations, LAN wiring, WAN technologies and circuit speeds, and power used.

Network Audit Tools

Three primary sources of information for performing a network audit: existing documentation, existing network management software tools, and new network auditing tools.
The network audit should provide information on:
- Network device list
- Hardware specifications
- Software versions
- Configuration of network devices
- Auditing tools' output information
- Interface speeds
- Link, CPU, and memory utilization
- WAN technology types and carrier information

Design Methodology

A top-down approach is used for network design, starting with the organization's requirements before looking at technologies.
Network designs are tested using a pilot or prototype network before moving into the Implement phase.
Top-down design adapts the network and physical infrastructure to the network application's requirements.
Network services include:
- Resiliency and control
- User services (mobility, performance, and security)
- Connection management (secure access anytime and anywhere)

Borderless Networks Architecture

Cisco Borderless Networks allow "anyone, anywhere, anytime, and on any device" to connect to an organization's network.
The product line was developed to meet the increased performance demands of streaming video, wireless networking, cloud and virtualization services, and the rising usage of smartphones and other consumer devices in the workplace.

Network Architectures

Cisco Network Architectures include borderless networks architecture and collaboration and video architecture.

Collaboration and Video Architecture

The Cisco collaboration and video architecture is composed of three layers:
- Communication and collaboration applications
- Collaboration services
- Infrastructure

PBM (Prepare, Plan, Design, Implement, Operate, Optimize)

The PBM lifecycle includes:
- Prepare: determining the network's current and future requirements
- Plan: developing a strategy and design
- Design: creating a detailed design document
- Implement: building and deploying the network
- Operate: maintaining the network's day-to-day operational health
- Optimize: proactively identifying and resolving issues before they affect the network

Plan Phase

The Plan phase is divided into three processes:
- Strategy and Analysis process
- Assessment process
- Design process

Build Phase

The Build phase is divided into three processes:
- Validation process
- Deployment process
- Migration process

Operate Phase

The Operate phase maintains the network's day-to-day operational health, including:
- Managing and monitoring network components
- Routing maintenance
- Managing upgrades
- Managing performance
- Identifying and correcting network faults

Optimize Phase

The Optimize phase involves proactive network management by identifying and resolving issues before they affect the network.

Design Methodology for PBM

A design methodology for the PBM methodology has three steps:
- Identifying customer network requirements
- Characterizing the existing network
- Designing the network topology and solutions

Identifying Customer Design Requirements

To obtain customer requirements, you need to talk to network engineers, business unit personnel, and company managers.
Steps to identify customer design requirements:
- Identify network applications and services
- Define the organizational goals
- Define the possible organizational constraints
- Define the technical goals
- Define the possible technical constraints
