  1. Network Topology Sub Sections Leanne Galletta, David Atkins, Andrew Carmichael

  2. Objective • Designing a network infrastructure for a new medical facility • Our design is focused upon two requirements: • achieving 99.99% system uptime, and supporting a minimum of 225 network users, 200 of which are mobile • The facility is comprised of two separate buildings: one serving as the main office, the other as a datacenter

  3. Network Description • A one-story datacenter and a one-story main office • The main office supports a minimum of two hundred and twenty-five users, twenty-five of whom are wired • In order to connect the two buildings without laying new cable, we will use a Virtual Private Network (VPN) to bridge them • VPN over the Internet allows the physically separated buildings to communicate as one network • Each building will use a hard line to an Internet Service Provider (ISP) to connect to the Internet

  4. ...Network Description Cont… • Each building will have its own router • DataRouter1 and MainRouter1 • Their WAN facing sides will connect to their building’s firewall, the firewall connecting to the Internet hard line • Both DataRouter1 and MainRouter1 are connected to their own WAPs, BackupWAP1 and BackupWAP2 • DataRouter1’s LAN side connects to DataSwitch1 (which connects to workstations, printers, servers) • primary and backup servers will run concurrently in a RAID1 • MainRouter1’s LAN side connects to MainSwitch1 (connected to workstations, IP printers, and two WAPs, FacilityWAP1 and FacilityWAP2) • Star topology will provide security, efficiency and ease of troubleshooting.

  6. Physical Network Diagram • Lenovo ThinkPad SL500 Laptop • HP Compaq dc5800 Workstation • Lexmark T 652n Laser Printer • HP Officejet Pro 8500 Printer • Dell PowerEdge R900 Server

  7. Physical Network Diagram • Cisco ASA5505 Firewall • Cisco ASR-9010-DC Router • Cisco Catalyst 4948 Switch • Cisco 521 Wireless Access Point • Cisco Aironet 1410 Wireless Bridge • Cyberpower CP550SL UPS • Cyberpower OL3000RMXL2U • CAT 6 Cabling (2000')

  8. Why Did We Choose Cisco Networking? • Need for reliability and durability, which Cisco Networking offers • Price, function, and the warranties and support provided by Cisco • Purchasing network hardware from a single vendor decreases the chance of compatibility and connectivity issues

  9. ….why we chose Cisco Networking cont… • Cisco ASA5505 Firewall • We require 2 firewalls; one for the main facility and one for the data center • Cisco ASR-9010-DC Router • We require 2 routers; one for the main facility and one for the data center • Cisco Catalyst 4948 Switch • We require 2 switches; one for the main facility and one for the data center • Cisco Aironet 1410 Wireless Bridge • We require 2 wireless bridges; one for the main facility and one for the data center • Cisco 521 Wireless Access Point • We require 2 wireless access points; both for coverage of the main facility

  10. Servers • Dell PowerEdge R900 Server • Chosen due to its power, reliability, and versatility • 10 units • 5 will be used as primary servers • 5 for backup servers

  12. Workstations • HP Compaq dc5800 based on their low cost and reliability. • 27 units • 25 for the main facility • 2 for the data center.

  14. Laptops • Design requirements did not specify whether the company needs hardware, already owns hardware, or plans to allow employees to use their own hardware. • 200 Lenovo ThinkPad SL500 laptops • In case the company requires hardware • Chosen due to their low cost and durability

  16. Printer Choice • Lexmark T 652n Laser Printer • 8 of these printers will be networked and shared among select user groups • For added security, the Director, CMO, and Physician on duty will use non-networked HP Officejet Pro 8500 printers

  18. Cabling • Network needs at least 2,000 feet of CAT6 cabling • CAT6 is chosen over CAT5e • Because rewiring is difficult, CAT6 provides better bandwidth breathing room and some degree of future proofing • All wiring in both buildings will be CAT6 Unshielded Twisted Pair (UTP)

  19. Disaster Recovery System • All of the workstations, servers, routers, switches, and wireless access points will need backup batteries • provides a short period of support for events such as brownouts or blackouts • CyberPower CP550SL UPS • long battery life and price • Cyberpower OL3000RMXL2U UPS • Provides a higher degree of power security has seamless power

  20. Backup Generators • Guardian Elite QT02516 • provides 25kW of power • We recommend purchasing a unit for both the data center and main facility • Purchasing a backup generator capable of powering the hospital is a necessity • 99.99% uptime is required for this facility • Allows a large period of time to repair any power issues and/or for management and staff to organize an evacuation

  21. IP Adressing • The hospital network a Class B IP address, 172.16.0.1 (because Class C addresses will only allow up to a maximum of 254 total available hosts for the network) • A Class B address will satisfy the current addressing needs and allow room for expansion in the future • The network will use this Class B IP address and internal subnetting to communicate the network designated static IP addresses to the external network IP addresses, 90.44.22.5 and 90.44.22.6 • All wired users will use static IP addresses • Wireless users will be provided IP addresses via DHCP through the FacilityWAP1 and FacilityWAP2 access points

  24. Network Operating Systems We Recommended • Windows Server 2008 • Ubiquity of Windows-compatible hardware • Easier to install and run than *nixes • Easier to learn then *nixes • Plethora of drivers • Red Hat Enterprise Linux 5 • Low, low price • Good selection of open-source security tools • Strong support system • Active open-source community • Sun Solaris 10 • Stability of Unix kernel • More secure than Linux/Windows • Low price • Fabulous ZFS file system
