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 5
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 6
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) 7
SDN Connectivity 19 Student buildings (801-816 & 901-913) connected through 8 core SM fiber at 1 Gbps Two fast Ethernet connections per each dorm room More than 2200 network points 8
RAS Connectivity 240 Users can simultaneously use Dial up service All faculty/staff dial (860)1010 & students dial 8601820 to connect to the RAS system Special services (increased connect time and callback service) are provided for limited users depending on their requirement 9
RAS utilization Max: 174 connections (72.5%) Avg: 84 connections (35.0%) Current: 68 connections (28.3.5%) 10
