5 KFUPM Network Model Three layer hierarchical model Core layer – Cisco Catalyst 6509 Provides high speed switching between the buildings Distribution layer – Catalyst 3550 Gateway for the individual building, interface between access layer and Core Access layer – HP 2524, Cisco 2950 Connects user’s desktop to the network

6 KFUPM Backbone Gigabit IP backbone Two core switches to provide full redundancy and load sharing, high availability Enterprise servers directly connected to core switch Switching fabric 256 Gbps Supports next generation of Video and Voice applications: Video on demand, audio/video streaming, voice chatting An important part of the university’s overall e- learning strategy

7 Academic Buildings Connectivity 35 Academic and Administrative buildings are connected through 8 core SM fiber at 1 Gbps (More than 5600 network points) 5 remote buildings are connected through HDSL links at 2Mbps (More than 70 network points)

8 SDN Connectivity 19 Student buildings ( & ) connected through 8 core SM fiber at 1 Gbps Two fast Ethernet connections per each dorm room More than 2200 network points

9 RAS Connectivity 240 Users can simultaneously use Dial up service All faculty/staff dial (860)1010 & students dial to connect to the RAS system Special services (increased connect time and callback service) are provided for limited users depending on their requirement

10 RAS utilization Avg: 84 connections (35.0%) Max: 174 connections (72.5%) Current: 68 connections (28.3.5%)

11 Major Achievements 2005 ADSL Wireless LAN DCC

12 ADSL Connectivity Faculty housing is connected to the KFUPM network using 24/7 ADSL links. Can accommodate 1000 lines. 512 Kbps Upstream channel and 1.5 Mbps Downstream channel. Dedicated 4 Mbps link for internet connection.

13 Wireless LAN Coverage: 37 Buildings covered, 344 wireless APs Scalability: 6000 users can simultaneously use WLAN Standard: IEEE IEEE 54 Mbps Mobility: Seamless roaming Secure communication: User authentication, Data Encryption

15 WLAN Security 802.1x based Wireless security PEAP as the authentication Protocol. WEP (128 bit) + TKIP for encryption. Cisco secure access control server Fortigate 1000 firewall, Fortireporter WLAN Infrastructure  Cisco 6506 core with WLSM blade  Cisco Inline Power switches 3560 for PoE  Cisco Aironet 1200 series access points  SSID for Fac/Stf is faculty and for students is student.  SSID for guest access is guest WLAN Management  WLSE

16 DCC Connectivity 696 network points DCC buildings are connected to KFUPM network through secure Wireless link Complete WLAN coverage Local services: DNS, DHCP, WINS, Active Directory, Filer, Patch management, Internet proxy

17 Internet Connectivity ATM (Asynchronous Transfer Mode) is being used for internet connectivity Directly connected to KACST Riyadh using STC ATM backbone over fiber 12 Mbps bandwidth for campus (being fully utilized) 4 Mbps bandwidth for ADSL (being fully utilized) 700 users are simultaneously using internet at peak times Technically can go up to 155Mbps PIX firewall is being used to ensure high level of security
