Needs analysis is the foundational step in network design, focusing on identifying the specific requirements of an organization to ensure the network meets its functional, performance, and scalability needs.
- This process evaluates the organization’s current and future demands in terms of applications, users, devices, and overall operational goals.
Key Components of Needs Analysis
1.) Network Architecture Component:
Network Architecture Component refers to the structural layers and design elements of the network.
- It ensures all aspects of the network (core, distribution, and access layers) align with the organization’s goals.
Key Considerations:
- Current and anticipated data traffic patterns.
- Required bandwidth and latency for specific applications.
- Physical infrastructure (cables, switches, and routers) and wireless access points.
2.) Application Systems:
Application Systems is the software applications and services that the network must support.
- It determines the bandwidth, latency, and reliability needs for critical applications.
Key Considerations:
- Types of applications (e.g., video conferencing, database access, file sharing).
- Resource-intensive applications requiring higher performance.
- Support for cloud-based or remote applications.
3.) Network Users:
Network Users is the individuals and devices that will access the network.
- It ensures the network supports all user needs efficiently.
Key Considerations:
- Number of users and devices (e.g., computers, smartphones, IoT devices).
- Location of users (onsite, remote, or hybrid).
- User roles and access levels, ensuring security and proper resource allocation.
4.) Categorizing Network Needs:
Categorizing Network Needs is grouping the identified requirements based on their priority and type.
- It helps prioritize resources for the most critical needs.
Key Categories:
- Performance Needs: Bandwidth, latency, and reliability.
- Security Needs: Firewalls, encryption, and access control.
- Scalability Needs: Ability to grow with the organization.
- Special Requirements: Unique needs, such as supporting specific devices or compliance with regulations.
4.) Deliverables:
Deliverables is the outcomes of the needs analysis phase, which guide the subsequent network design.
- It ensures clear communication and alignment among stakeholders.
Key Deliverables:
- A detailed report of current network performance and gaps.
- A prioritized list of requirements for the new network.
- Preliminary design recommendations for addressing the identified needs.
Importance of Needs Analysis
- Improved Efficiency: Ensures the network is optimized for current and future use.
- Cost Management: Avoids over- or under-investment in resources by focusing on real needs.
- Scalability: Lays the groundwork for a network that can grow with organizational demands.
- Enhanced Security: Identifies potential vulnerabilities and requirements for secure access.
