Student Dorms Buildings (19) Academic Buildings (40) RAS Dialup Users (240) ADSL WLAN DCC Network Core
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
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
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)
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
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
RAS utilization Max: 174 connections (72.5%) Avg: 84 connections (35.0%) Current: 68 connections (28.3.5%)
