You are a consultant for being brought in by XUMUC to assist with a merger with another company. XUMUC is has the WAN links in place to the new locations in the Houston Region. XUMUC currently has 2 other Regions San Francisco and Denver. Originally, XUMUC was only in one region (San Francisco). The previous consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus are very large. In addition, no VLAN structure was developed to isolate broadcast traffic. There are 4 main departments in XUMC: sales, finance, human resources, and research and development. Also, there has been some concern that the WAN transport was not able to accommodate the network traffic. Finally, all addresses in the network are statically assigned resulting in high administration overhead when changes are needed XUMC would like this changed to lower administrative overhead. IP ADDRESSING TABLE Provide a document that addresses all issues described above. The document should contain:

Title: Network Optimization and Integration Plan for XUMUC’s Merger

The purpose of this document is to provide a comprehensive plan for optimizing and integrating the network infrastructure of XUMUC, a company preparing to merge with another organization. The current network infrastructure poses several challenges, including poor IP address scheme, large routing tables, lack of VLAN structure, and limited WAN transport capacity. This document will address each of these issues and propose effective solutions to improve network performance, security, and administration efficiency.

1. IP Addressing Scheme:
The existing IP address scheme in XUMUC is poorly designed, resulting in large routing tables at summarization points and the San Francisco Campus. To rectify this issue, a reconfiguration of the IP addressing scheme is necessary. The proposed solution involves implementing a hierarchical addressing scheme utilizing subnetting and variable-length subnet masking (VLSM). This will allow for efficient routing and easy scalability while minimizing the size of routing tables. Additionally, the use of dynamic addressing mechanisms, such as DHCP (Dynamic Host Configuration Protocol), should replace static IP assignments to reduce administrative overhead.

2. VLAN Structure:
To isolate broadcast traffic and improve overall network security and performance, it is imperative to develop a VLAN (Virtual Local Area Network) structure. Implementing VLANs will provide logical segmentation of network resources based on departmental or functional requirements. For XUMUC’s four main departments (sales, finance, human resources, and research and development), separate VLANs should be created to ensure broadcast traffic is contained within each department’s network segment. This segmentation will enhance network security by limiting the scope of potential security breaches and reduce the impact of broadcast storms.

3. WAN Transport Capacity:
XUMUC’s concern regarding the WAN transport’s ability to handle network traffic should be addressed to ensure optimal performance. A thorough analysis of current bandwidth utilization and projected growth in network traffic is necessary to determine whether additional bandwidth is required. If there is a shortfall in the existing WAN transport capacity, considerations should be made to upgrade the network infrastructure either by increasing the bandwidth or implementing technologies like WAN optimization. This will enhance network reliability, reduce latency, and improve overall user experience.

4. Administrative Overhead:
XUMUC’s reliance on static IP address assignments results in high administrative overhead when changes are needed. To alleviate this burden, the implementation of dynamic IP addressing through DHCP is recommended. DHCP will automate the IP address assignment process, allowing for centralized management and efficient allocation of IP addresses. Additionally, the use of DHCP will also facilitate easier network troubleshooting and maintenance, as well as support features like lease renewal and IP address reservation.

By addressing the issues highlighted in this document regarding IP addressing, VLAN structure, WAN transport capacity, and administrative overhead, XUMUC will be able to optimize its network infrastructure in preparation for the merger. The proposed solutions will enhance network performance, security, scalability, and streamline administrative processes, ultimately supporting the company’s growth and operational efficiency.
