Paper For Above instruction
Introduction
In today’s increasingly interconnected world, ensuring a robust, secure, and efficient network infrastructure is essential for supporting business operations, especially in environments like DesignIT, a growing graphic arts company. With the recent purchase of a dedicated space designed to host multiple servers, computers, printers, and wireless devices, the importance of comprehensive network planning becomes evident. This paper presents a detailed network consultation proposal, including recommended designs, architecture, wiring considerations, hardware and software options, security strategies, cost analysis, and risk mitigation plans to ensure the seamless operation of DesignIT’s new facility.
Network Design Recommendation
The proposed network design for DesignIT centers on establishing a hybrid network infrastructure that combines wired Ethernet connections for core devices and critical servers, with wireless access points for portable devices and staff mobility. Given the requirement for high-speed internet access, secure data handling, and reliability, a switched Ethernet LAN with VLAN segmentation is recommended. This design ensures efficient data flow, reduces network congestion, enhances security, and simplifies management.
Network Architecture
The suggested architecture adopts a star topology centered around a high-performance core switch. The layout includes dedicated subnetworks for servers, administrative staff, and guest wireless access, segmented via VLANs. The three existing servers—Web Server, File Server, and Small Business Server—will be housed in the dedicated server room, connected via multiple fiber optic links for high bandwidth and low latency. Wireless access points strategically placed in common areas and conference rooms will provide WLAN connectivity. High availability and load balancing configurations are integral to the architecture, reducing the risk of downtime.
LAN and Wireless LAN Wiring Considerations
The LAN wiring involves Cat6a Ethernet cabling capable of supporting gigabit speeds and future upgrades. The wiring plan emphasizes structured cabling standards, proper cable management, and labeling for scalability and troubleshooting. The WLAN setup utilizes multiple access points connected via Ethernet to the core switch, ensuring comprehensive coverage with minimum dead zones. Power over Ethernet (PoE) technology is recommended for access points to simplify installation and management.
Hardware Options and Costs
For the core network, a managed gigabit switch with VLAN capabilities and redundancy features is essential. Server-grade switches such as Cisco Catalyst series or Ubiquiti UniFi switches are suitable options. Network routers capable of handling high throughput and security features, such as Cisco ISR models, are recommended. End-user devices include six workstations with Ethernet and wireless access, color laser printers connected via Ethernet and wireless, and security appliances like dedicated firewalls. Approximate hardware costs range from $5,000 to $8,000 depending on vendor and specifications.
Security Considerations
Firewall: Installing a next-generation firewall (NGFW) such as Cisco ASA or Palo Alto Networks PA series is recommended to safeguard against external threats, with features like intrusion detection/prevention, application awareness, and VPN capabilities.
Antivirus Software: Deploy comprehensive endpoint security solutions such as Symantec Endpoint Protection or Sophos, providing real-time malware detection, threat prevention, and automated updates to protect all networked devices.
Software Options and Costs
Common network management software such as SolarWinds Network Performance Monitor or Nagios can facilitate monitoring, troubleshooting, and bandwidth management. Licensing costs vary but typically range from $1,000 to $3,000 annually, depending on the scale.
Cost Analysis
| Cost Category | Details | Approximate Cost |
|---|---|---|
| Labor Costs | Network installation, configuration, testing | $2,500 |
| Equipment Costs | Switches, routers, access points, servers, printers | $6,000 |
| Service and Maintenance | Annual warranty, support, updates | $1,200 |
Single Point of Failure and Mitigation Strategies
The primary single point of failure identified is the core switch. To mitigate this, installing redundant switches with failover capabilities (e.g., spanning tree protocol configurations) will ensure continuous network availability. Additionally, backup power supplies (UPS) for critical devices and regular data backups will minimize downtime during outages.
Conclusion
Implementing the proposed network design for DesignIT will facilitate secure, high-speed, and reliable connectivity that supports current operational needs and future growth. The combination of wired and wireless components, robust security measures, and strategic redundancy planning will position DesignIT for success in its expanding business environment. The detailed cost analysis and mitigation strategies further ensure that the network infrastructure remains resilient and scalable, aligning with best practices in network engineering.
