    Study Notes

    Network Design

    • Designing a network for an organization requires identifying organizational objectives and network goals.
    • A general network goal for most organizations is installing an economical network, incorporating modern communication technologies, and allowing for future expansion.
    • Specific company goals may include sharing information and printers between computers, adding more computers, or providing internet access to specific groups.
    • Important, technical goals are scalability, availability, performance, and security.

    Peer-to-Peer vs. Server-Based Networks

    • The first design decision is whether the network should be peer-to-peer or server-based.
    • Factors to consider include network size, security level, type of business, administrative support, network traffic, user needs, and budget.
    • Peer-to-peer networks have drawbacks like challenges in sharing resources when computers are turned off or malfunctioning, and limited security. User responsibility for security and data is prevalent.

    Server-Based Networks

    • In server-based networks, resources are centralized.
    • A server, such as a print server, manages resources like printers, while another server manages files.
    • Server-based networks are scalable and resources are generally available.
    • Security is enhanced in server-based networks by managing accounts and permissions.

    Hybrid Networks

    • Hybrid networks combine peer-to-peer and server-based network approaches.
    • The basic network can be peer-to-peer with dedicated servers, like a file server.
    • File server access requires user accounts and permissions, whereas access to other computers is shared.

    Network Inventory

    • Taking an inventory of existing hardware and software is crucial for planning future network expansion.
    • The inventory includes hardware (computers, peripherals, cabling, etc.) and software (programs and versions).
    • Inventory helps in assessing the existing network setup to align with the organizational needs.

    Hardware Survey

    • A hardware inventory needs to include the make and model of each computer and its components (proccessor, memory, hard drive).
    • Information on peripherals, video cards, and other installed drives is also crucial.
    • Free slots for expansion cards need to be accounted for in surveys.

    Software Survey

    • Gathering software information, such as programs, versions, installation media, and licensing agreements, is essential for a complete inventory.

    Telecommunications Equipment Survey

    • This survey documents the type of cables (with accessories) and modems and network interfaces (NICs).

    Network Topology

    • Network topology is a pictorial representation of network configurations, including network nodes and connections.
    • This selection stage defines how network segments are connected, and what internetworking devices (like hubs, switches, and routers) are required.
    • A hierarchical model is commonly used for enterprise LAN/WAN networks. It consists of three layers: core, distribution, and access.

    Core Layer

    • The core layer acts as the backbone, optimizing packet switching speed and performance.
    • Servers and user machines are not typically connected to the core layer.
    • Packet manipulation and traffic management are performed at other layers.

    Distribution Layer

    • The distribution layer acts as a demarcation point between the access and core layers.
    • It defines boundaries, and can perform tasks like traffic redirection, filtering, and security.
    • Functions like address aggregation are frequently implemented here to ensure optimized flow and administration.

    Access Layer

    • The access layer connects users and devices directly into the network.
    • It can involve optimization such as bandwidth sharing, switched bandwidth, MAC layer filtering, and micro-segmentation for the users.

    Network Requirements

    • After surveying the facility and equipment, the requirements for the network need to be established and matched with the existing hardware, software, and communication features.
    • Determining the steps to complete the network design is crucial.

    Network Layout and Media

    • The physical layout of the network includes the locations of hardware and their interconnections.
    • The topology needs to be mapped, including all devices and peripherals.
    • Choosing the correct network media (like fiber optic or twisted pair cable) depends on the environment, such as manufacturing facilities or office buildings.

    Project Timeline

    • A project timeline, like a Gantt chart, should be developed for the implementation of the designed network.
    • The schedule helps manage tasks, including vendor selection, system installation, and network connectivity setup, and training.

    Final Proposal

    • The final design proposal summarizes the design plan and requirements for the client.
    • Proposals should include executive summaries, project goals, scopes, and detailed design requirements (both technical and business), as well as current-state, logical, and physical network designs.
    • The budget and any associated expenses should also be described.
