Gathering Network Requirements
Designing and Supporting Computer Networks – Chapter 2
Objectives
Explain how the Cisco Lifecycle Services approach enables organizations to prepare, plan, design, implement, operate and optimize a network that supports the introduction of new technologies. Describe sales activities and the role of the network designer in the pre-sales process. Explain the process of creating a network design and the information needed before the process can begin. Identify technical requirements and constraints of the organization to determine the scope of the project. Explain design considerations for manageability.

Identify Requirements and Constraints to Determine the Scope of the Project
Identify the constraints that affect the network design, including cost, schedule, and resource constraints
Explain Design Considerations for Manageability Top-down design approach:
Adapt the network to the needs of the organization Take the design from the perspective of the required network solutions
Explain Design Considerations for Manageability Typical network management architecture:
Network Management System (NMS)
Network Management Protocol
Managed devices
Management agents
Management information
Explain Design Considerations for Manageability
Network monitoring tools can be used to page or send email to on-call technicians Tools respond to network fault or when a predefined threshold is met
Summary
The six phases of the network lifecycle include prepare, plan, design, implement, operate, and optimize. A project plan includes tasks, timelines, risks, responsibilities, and resources required to complete a network design project. Following the required format and schedule is critical to submitting a successful proposal. All members of the networking contractor staff must demonstrate effective interpersonal skills. Top-down network design strategies have the best chance to succeed. A primary requirement for any network is the availability of qualified support personnel.
