XUMUC has 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 XUMUC would like this changed to lower administrative overhead.

Title: Analysis of Network Issues and Proposed Solutions for XUMUC


XUMUC is currently facing several network-related challenges, including poor IP address scheme integration, large routing tables, lack of VLAN structure, congestion in WAN transport, and high administrative overhead. This paper will analyze these issues and propose solutions to improve the network infrastructure and optimize its performance.

Analysis of Network Issues:

1. Poor IP Address Scheme Integration:
The previous consultant’s inadequate job of integrating the IP address scheme has resulted in a complex and inefficient network. The routing tables at the summarization points and San Francisco Campus are excessively large, leading to increased processing time and potential routing errors.

2. Lack of VLAN Structure:
The absence of a VLAN structure poses a security risk due to the absence of segregation of broadcast traffic. This can lead to excessive network congestion and unauthorized access to sensitive data.

3. Congestion in WAN Transport:
There are concerns regarding the WAN transport’s ability to handle the network traffic adequately. The existing WAN links may be insufficient, resulting in slow data transfer speeds and decreased network performance.

4. High Administrative Overhead:
All addresses in the network are statically assigned, which increases administrative workload and introduces the possibility of configuration errors. This manual approach is time-consuming and prone to human mistakes. An efficient allocation and management system for IP addresses is required to reduce administrative overhead.

Proposed Solutions:

1. IP Address Scheme Improvement:
To address the issues caused by the poor IP address scheme integration, XUMUC should implement a well-designed and hierarchical IP addressing plan. This plan should incorporate subnetting and proper IP allocation for each region, campus, and remote office. By utilizing a hierarchical IP addressing scheme, routing tables can be simplified and network efficiency can be enhanced.

2. Implementation of VLAN Structure:
To isolate broadcast traffic and improve network security, XUMUC needs to implement a Virtual Local Area Network (VLAN) structure. This will separate different departments, such as sales, finance, human resources, and research and development, into their respective VLANs, preventing unnecessary broadcast traffic and reducing network congestion.

3. Evaluation and Upgrade of WAN Transport:
XUMUC should assess the current WAN transport’s performance and capacity to ensure it can handle the network traffic appropriately. If inadequacies are identified, XUMUC should consider upgrading the WAN links or utilizing additional bandwidth, such as MPLS or SD-WAN solutions, to enhance network performance and ensure efficient data transfer between locations.

4. Implementation of Dynamic Address Allocation:
To reduce administrative overhead, XUMUC should adopt a dynamic address allocation system, such as Dynamic Host Configuration Protocol (DHCP), instead of statically assigning IP addresses. DHCP will automate the IP address assignment process, lowering administrative workload and reducing the risk of configuration errors.


In conclusion, XUMUC faces several network issues that impact its overall performance and efficiency. This analysis has proposed several solutions, including improving the IP address scheme integration, implementing a VLAN structure, evaluating and upgrading the WAN transport, and adopting dynamic address allocation. By implementing these solutions, XUMUC can achieve a more optimized and reliable network infrastructure, reducing administrative overhead and enhancing network performance.
