Study Notes
Network Design Basics
- A small network is usually simple in design.
- The person responsible for managing a small network is typically the IT staff or a small business owner.
Network Planning Considerations
- One of the first design considerations when planning a network is the number of users and devices.
- Factors influencing the cost of switches or routers include speed, features, and brand.
- Another key element affecting cost considerations in a network design is scalability.
Layer 2 Devices and Switches
- Choosing Layer 2 devices that can accommodate increased speeds offers advantages such as future-proofing and easier upgrades.
- Additional ports on switches are used for expansion or connecting devices.
Network Management and IT Department
- The IT department's role in managing a large network is to ensure smooth operation, maintenance, and troubleshooting.
- Planning ensures that a network is scalable, efficient, and meets business needs.
Network Size and Type
- The majority of businesses are small to medium-sized.
- Most business networks are also small to medium-sized.
Networking Devices
- Routers are used to connect different types of networks.
- A hub is a type of networking device that cannot be expanded.
IP Addressing and Redundancy
- Having an IP addressing scheme in a network ensures that devices can communicate with each other.
- One way to accomplish redundancy in a network is through duplicate devices or connections.
- Redundancy is important in network design to ensure network reliability and minimize downtime.
Network Configuration and Goals
- Routers and switches should be configured to support the required number of devices and traffic in a small network.
- The goal of a good network design for a small network is to provide a reliable, efficient, and scalable infrastructure.
- The recommended approach for selecting modules and interfaces in networking devices is to consider the business's current and future needs.
- Small businesses should consider network reliability and scalability when designing their network.
