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%)
