  1. Mountain Sky Elementary Network Proposal by H.B.O. Systems July 13, 2000 Presenters: Janet Hughes, John Banister, Karen Oliver

  2. Design Team Goals • Provide the best QoS for cost • Facilitate high quality training • Assist in planning for future growth and development: • 1000% LAN growth • 100% WAN growth • Network life span of 7 to 10 years

  3. Local Area Network (LAN) Infrastructure • 3 Servers • 1 Enterprise Server • Student & Staff Directory, Application Services (Microsoft Office, etc.), DNS/E-mail, Library Services, Novell Netware • 2 Workgroup Servers • Student - Curriculum Applications • Administrative - Grades, Attendance, Student Information

  4. LAN Infrastructure Continued • Main Distribution Facility (MDF) located near Point Of Presence (POP) • Vertical Cable to Intermediate Distribution Facility and Portable Classrooms • Fiber • Meet EIA/TIA 568 cable standards • Horizontal Cable • Minimum of Cat. 5 Unshielded Twisted Pair (UTP) cable • Accommodate 100 Mbps • Meet EIA/TIA 568 cable standards

  5. LAN Infrastructure Continued • Classrooms • 4 Cat. 5 UTP drops • 24 student stations with at least 1 Mbps bandwidth • Each student drop will have a 12 port hub connected • 1 teacher station with at least 1 Mbps bandwidth • Lockable Cabinets

  6. Building A East Main Distribution Facility (MDF) Point of Presence (POP) Building A West Intermediate Distribution Facility (IDF) Building A East Double Portable Classrooms Multi-Purpose Building Mountain Sky Elementary Building Layout

  15. MDF Logical Layout Greenway C.O. Service Center Cisco 7576 Router Indicates 100BaseTX cable Virtual Local Area Network 1 (VLAN 1) Virtual Local Area Network 2 (VLAN 2) Enterprise Server Student/Curriculum Server Administrative Server Indicates 100 Base SX from switch to IDF (33 - 12 port hubs) IDF-1 IDF-2

  16. IDF-1 Layout Located in MDF Cisco 5500 stackable - 312 Port Switch 100BaseSX Fiber from MDF to IDF Indicates four 100BaseTX cables Each classroom with have 3 - 12 port hubs

  17. IDF-2 Layout Located in MDF 100 Base SX Fiber from MDF to IDF IDF-1 Cisco 1900 - 24 port switch - 1 in each portable classroom Indicates four 100BaseTX cables Each classroom will have 3 - 12 port hubs

  18. Security • Users will be restricted through the use of VLAN’s • Every administrative node gains server rights through a user password • Access outside the LAN is through the District Office • Outside access to LAN is prohibited through the use of access lists • Firewalls are utilized through access lists locally and globally

  19. IP ADDRESS ASSIGNMENTS S0 S1 S2 District Office 190.191.10.3 190.191.10.2 190.191.10.1 Greenway Center 192.191.128.3 192.191.128.1 192.191.128.2 SunnySlope 191.191.0.1 191.191.0.2 191.191.0.3 S0 E0 E1 Mountain Sky 220.100.10.1 220.100.10.3 220.100.10.2 Curriculum Subnet Address 220.100.10.2 Administrative Subnet Address 220.100.10.3

  20. Network Address Translation Network Address Translation (NAT) is designed for IP address simplification and conservation, as it enables private IP internetworks that use nonregistered IP addresses to connect to the Internet. NAT operates on a router, usually connecting two networks together, and translates the private (not globally unique) addresses in the internal network into legal addresses before packets are forwarded onto another network. As part of this functionality, NAT can be configured to advertise only one address for the entire network to the outside world. This provides additional security, effectively hiding the entire internal network from the world behind that address. NAT has the dual functionality of security and address conservation, and is typically implemented in remote access environments.

  21. Access List Policy External Threats: Internet connectivity will utilize a double firewall with all internet-exposed applications residing on a public backbone network. All inbound traffic from the internet into the school’s private network will not be blocked by the double firewall. No traffic from the curriculum LAN will be permitted into the Administrative LAN.

  22. Access List Code RouterA(Config)# Access-list 100 permit ip 192.191.128.0 0.0.0.255 RouterA(Config)# Access-List 100 permit ip 191.191.0.0 0.0.255.255 RouterA(Config)# Access-List 100 deny ip 190.191.10.1 0.0.0.0 RouterA(Config)# Access-List 100 permit ip 0.0.0.0 255.255.255.255 RouterA(Config)# Int s0 RouterA(Config-if)# Access-group 100 in

  23. Access List Code (con’t) RouterA(Config)#Access-List 101 deny ip 200.100.10.3 0.0.0.0 RouterA(Config)#Access-List 101 permit ip 0.0.0.0 255.255.255.255 RouterA(Config)#Int e0 RouterA(Config-if)#Access-group 101 in
