  1. Threaded Case Study on RE MillerByAidan ColemanPaul Guilfoyle

  2. Presentation Outline • Objective • User Requirements • LAN/WAN Design Considerations • Servers/Internet Access • ACL’s • Equipment List • Advantages / Disadvantages

  3. Objective • The Washington School District is designing a district wide computer network for the purpose of providing online automation of administrative and curricular functions between all of the schools and administrative offices in the network. • The LAN/WAN design will need to meet the requirements of growth, functionality, security and cost.

  4. User Requirements • Network Functional Life: 7-10 years • Anticipated Growth: LAN- 100 times WAN - 2 times District Internet Connectivity – 10 times • Speed: To workstations - 1 Mbps To Servers- 100 Mbps • Protocols:TCP/IP • Internet Access:Frame Relay

  5. LAN Requirements • LAN Infrastructure – Two LAN’s • LAN infrastructure based on Ethernet LAN switching. • 1.0 Mbs will be provided to any host and 100 Mbs to any server host • Will use Extended Star Topology

  6. Classroom Requirements • 24Student workstations • 1 Teacher’s workstation • Lockable Closet for patch panel and hubs • 4 Cat 5 UTP drops to each classroom from MDF/IDF

  7. Servers • Enterprise Servers for Master DNS Administrative Database Email /Internet Server File/Print Server  • Workgroup Servers for Administration Server Library Server Application Server’s

  8. Wiring Scheme • The Richard E. Miller campus consists of four permanent buildings and seven portable classroom buildings.We will have one MDF and three IDF’s. • The MDF and POP are located in the Multi-Purpose Building • Fiber optic cable will connect each IDF to the MDF. • Four Cat5 UTP cable runs to each room to support 24 student computers and 1 teacher computer.

  9. Addressing • Class C Address in District Office • Require 250 Addresses for Students and 75 for teachers/administration • Static Addressing for Teachers/Admin • Dynamic for Students (using DHCP) • Use NAT for internal addressing

  10. Addressing cont’d • Assume RE Millers is 200.200.1.10 • We use Network Address Translation to convert for the internal addresses • Use Class A Addresses Internally 10.10.1.0 Teachers 10.10.2.0 Admin 10.10.3.0 Students

  11. Security • Access from Internet is denied, using access lists • Unauthorised addresses will be prohibited • Separate VLAN’s for students,teachers and administration

  12. Security cont’d • Will use Access Control Lists to secure site from external access – Apply to Router Interface connecting to WAN • ACL’s to allow staff perform certain tasks e.g Allow IT team to telnet Access-list 101 permit telnet 10.10.2.0 0.0.0.255 10.10.2.0 0.0.0.255 eq 23 • Also use ACL’s to deny students access to unauthorised websites – Apply to Router Interfaces connecting to LAN

  13. Equipment Required DetailsQuantity Router 1 48 Port Switch 4 24 Port Switch 2 8 Port Hubs 120 Fiber 1,400 ft CAT5 20,000 ft

  14. Advantages • Room for future growth in LAN and WAN • Hubs can be replaced by switches to increase bandwidth • Enhanced seurity through use of both VLANs and ACL’s

  15. Disadvantages • No redundancy in cable layout • Possible areas for traffic congestion • DIFFICULT ASSIGNMENT
