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 (801-816 &

901-913) connected through 8 core SM fiber at 1 Gbps
