High Level Drawing: WAN Links Bandwidth In Your Group Invent

High level drawing. WAN links bandwidth in your group Inventory and IP scheme Scope of work

I have attached the case study. These are what need to be completed for my homework: high-level drawing, WAN links bandwidth in your group, inventory and IP scheme, scope of work, wireless network, VoIP design.

The first step in network design or upgrading an existing network is defining the scope of work, which is typically outlined in the client's Request for Proposal (RFP). This serves as a baseline for developing the scope and ensures clarity on project objectives and requirements. In this case, you will gather information about the client's business goals and technical requirements. To do this, interviewing upper management can clarify the business objectives, while technical requirements can be obtained from the IT department. In a real-world scenario, this validation step is crucial to ensure accuracy, but for this assignment, you may role-play interviews or proceed with the RFP as the scope of work.

Preparing an inventory list is essential for understanding existing equipment and planning upgrades. This can be conducted using software tools or through physical verification of the equipment. The inventory should include all operational devices as well as any new equipment anticipated for deployment. Using an inventory template relevant to your course can streamline this process.

The creation of a high-level existing network drawing is critical to visualize the current infrastructure. This diagram should encompass all key components such as connecting devices (routers, switches), security devices (firewalls, IDS/IPS), wireless access points, VLANs, and subnets. In practical scenarios, client-supplied network drawings often require updates to accurately reflect the actual onsite topology. Adjust the diagrams accordingly to ensure they match the real-world setup.

Developing an IP scheme involves planning the addressing structure for the network, including subnetting strategies for efficient IP utilization and security. This scheme should align with organizational requirements and facilitate network segmentation where necessary.

Calculating WAN link bandwidth for your voice network involves analyzing the expected voice traffic, the number of concurrent calls, and the quality requirements. Adequate bandwidth must be provisioned to maintain high call quality, prevent latency issues, and support scalability.

The wireless network design should address coverage, capacity, security, and redundancy. Consider deploying access points strategically to ensure seamless connectivity across the premises, implementing security protocols such as WPA3, and planning for future expansion or higher user density.

The development of a comprehensive network design plan begins with clearly defining the scope of work, a critical step aligned with the client’s Request for Proposal (RFP). The scope encompasses understanding business goals, technical needs, existing infrastructure, and future growth plans. In real-world projects, this step involves detailed interviews with management and IT staff, which help validate and supplement the information provided in the RFP. Given the constraints of this assignment, the scope will be based on the provided RFP, serving as a foundational document for subsequent planning.

Creating an accurate inventory of existing network equipment is vital for understanding current operational capabilities and identifying areas for improvement. This process involves cataloging all active hardware and anticipated upgrades, either through software tools or physical verification. An organized inventory facilitates informed decision-making around equipment replacement, expansion, and integration.

Developing a high-level existing network diagram provides a visual overview of the infrastructure. This diagram maps out all critical components, including routers, switches, security devices, wireless access points, VLANs, and subnets. To ensure accuracy, the diagram should be an updated reflection of onsite topology, especially if there are discrepancies between client-supplied drawings and actual deployment. Such visualizations are essential for identifying connectivity issues, planning future expansions, and communicating system architecture to stakeholders.

Implementing an IP addressing scheme ensures efficient network segmentation, security, and management. Subnetting strategies should be designed based on organizational requirements, considering factors such as departmental separation, security zones, and scalability. The scheme must facilitate easy troubleshooting and support network growth.

For voice network bandwidth planning, calculating WAN link capacity is essential to maintain call quality and system reliability. This involves estimating the number of concurrent voice calls, analyzing traffic patterns, and provisioning sufficient bandwidth to avoid latency, jitter, or packet loss issues. Adequate bandwidth planning supports scalable and reliable voice communication across the organization.

The wireless network design must focus on providing reliable coverage, supporting high user density, and ensuring security. Strategic placement of access points, proper channel planning, and adherence to security protocols such as WPA3 are crucial. Future-proofing by considering potential expansion and higher bandwidth demands will help maintain seamless wireless connectivity as organizational needs evolve.

In conclusion, a comprehensive network design includes defining scope, inventory management, detailed topology visualization, IP planning, bandwidth calculation, and wireless planning. Each component contributes to creating a reliable, scalable, and secure network infrastructure aligned with the organization’s business goals and technical requirements, thereby supporting operational efficiency and future growth.
