Paper For Above instruction

The modern enterprise heavily depends on robust, secure, and scalable network infrastructure to facilitate daily operations, support remote and local connections, and ensure business continuity. The case of Linket Cooperation exemplifies the critical need for network reengineering to address existing shortcomings such as frequent downtime, sluggish response times, and weak inter-branch connectivity. This paper explores the comprehensive process involved in redesigning Linket’s network infrastructure, emphasizing strategic planning, technical upgrades, implementation, and evaluation, supported by scholarly insights and industry best practices.

Introduction

In an increasingly digital world, organizations like Linket Cooperation must maintain efficient, reliable, and secure networks to remain competitive and protect sensitive data. The company’s current network suffers from frequent outages and slow responses, especially during peak hours, impairing productivity and resulting in operational inefficiencies. The motivation for this redesign is driven by these operational challenges and the goal to enhance security, scalability, and overall network performance. As noted by Olifer and Olifer (2010), effective network design is foundational to organizational success, particularly when addressing burgeoning data transmission demands and security concerns.

Assessment of Current Network Challenges

Linket’s existing infrastructure is hamstrung by several issues. The intermittent downtime hampers productivity, resulting in lost revenue and employee frustration. Slow response times during evenings exacerbate user dissatisfaction and hinder critical operations. Additionally, weak connections between the head office and remote branches, located at varying distances from New York, contribute to inconsistent communication and data exchange. These performance bottlenecks stem from outdated hardware, insufficient bandwidth, and non-optimized architecture, as discussed in Comer (2015). The current reliance on hubs instead of managed switches further jeopardizes security, exposing the network to potential threats, including unauthorized access and data breaches.

Design Objectives and Strategy

The primary design objectives align with modern network requirements: improve speed, increase capacity, enhance security, and boost fault tolerance. To meet these, a multi-faceted approach integrating hardware upgrades, architectural reorganization, and security protocols is essential. Implementing Virtual Local Area Networks (VLANs) for departmental segregation aligns with White’s (2016) emphasis on segmentation for security and management. Replacing hubs with managed switches elevates security by enabling features such as access control and port security, which are crucial as organizations expand their network boundary. Upgrading the connection from PSTN lines to T3 links ensures high-speed, reliable data transmission necessary for real-time applications such as video conferencing and VoIP, as specified by Olifer and Olifer (2010).

Logical and Physical Network Design

The logical topology comprises three zones: the enterprise campus, enterprise edge, and the service provider edge. This segmentation facilitates optimized management, remote connectivity, and scalability. The enterprise campus encapsulates the head office’s local network, supported by switches and servers interconnected through high-speed links. The enterprise edge connects remote branches using reliable fiber-optic links, tailored to their respective distances. The service provider edge manages external connections, ensuring redundancy and resilience.

Physically, the design incorporates a centralized data center housing mainframes and servers interconnected via CAT 5 cabling and wallplates. Each department connects through managed switches that support VLAN segmentation, enhancing both security and network efficiency as per White (2016). Routers connect branch sites, utilizing fiber optics where distance warrants, ensuring high-speed links are maintained over miles. This physical and logical layout aligns with best practices for enterprise network design, emphasizing scalability, security, and performance.

Testing and Implementation

Extensive testing of the new design indicated successful throughput improvements and better branch-to-head office connectivity. The tests demonstrated faster transmission speeds, reduced latency, and downtime minimization during peak hours. Implementation will be phased, starting with weekend testing to minimize operational disruption. Final deployment during normal business hours, with contingency plans to address potential issues, ensures seamless transition. Validation of network device configurations, service levels, and connectivity will be integral to this process, following industry standards (Olifer & Olifer, 2010).

Cost and Benefit Analysis

The projected overall investment over three years amounts to approximately $183,207.53, covering hardware, licensing, setup, and ancillary costs. The annualized expenditure stands at $61,069.18. Benefits forecasted include tangible savings of $100,000 annually from operational efficiencies and intangible benefits valued at $65,000, such as improved employee satisfaction and security. The cost-benefit ratio of approximately 0.37 indicates that the benefits substantially outweigh the costs, with the investment recuperated within the first year, aligning with economic principles outlined by White (2016) and others (Comer, 2015).

Conclusion

Overall, the planned network redesign for Linket Cooperation exemplifies a strategic, technologically sound approach aligned with industry standards and organizational goals. By upgrading hardware, reorganizing network topology, and implementing security measures such as VLANs and managed switches, the company will significantly improve network performance, reliability, and security. The phased implementation approach and comprehensive testing ensure minimal disruption and high success probability. The considerable benefits, both tangible and intangible, demonstrate that this investment not only addresses current issues but also positions Linket for future growth and technological evolution. As digital enterprises continue to expand, robust network infrastructure remains a cornerstone of operational excellence and security, as reinforced by leading industry literature.
