INTERNATIONAL GRAMMAR SCHOOL

International Grammar School opened in Randwick in 1984 with the unique educational objective of providing bilingual education from preschool onwards, coupled with the promotion of internationalism, music and racial tolerance. In 1997 the School relocated to new premises in Ultimo.

Situation

The increasing demand for networked educational resources from students and teachers was limited by an insufficient and poorly implemented systems infrastructure. The school’s employees and students were becoming sceptical about whether technology could truly enhance education in school or whether it might always remain a source of frustration and disappointment.

The Missing Link was initially engaged to investigate the cause of poor network performance across the campus, particularly in new classrooms in the recently refurbished east and west school wings. It was found that network stability across the whole school was extremely poor and the new classrooms experienced continuous communication loss with the core network.

A review of the physical infrastructure found that the network poorly planned, with a mix of unmanaged switches and hubs. Additionally, the outer classrooms were being supplied by copper infrastructure despite being well outside the maximum transmission distance.

Solution

The Missing Link engaged with Cisco Systems to design, supply and implement new network switching infrastructure to provide reliable and stable access to network based information resources. Additionally, additional fibre and CAT5 cabling was implemented to extend the reach of the network throughout the three wings of the campus.

The Cisco infrastructure consisted of:

  • A Cisco Catalyst 4507R Multilayer Core Switch with redundant Catalyst Supervisor IV engines. This switch supplies gigabit links to all access-layer switching infrastructure distributed around the campus.
  • A Cisco Catalyst 3750 Multilayer Access Switch to provide aggregated gigabit Ethernet access to the server infrastructure in the campus data centre.
  • A Cisco Catalyst 2970 Access Layer Switch to provide aggregated gigabit Ethernet links to switching infrastructure in the campus’ Bay Street Wing.
  • Cisco Catalyst 2950 Access Layer Switches to supply fast Ethernet access to all personal computing equipment.

Result

International Grammar School gained a fast, stable network platform, delivering reliable access to critical applications and learning utilities. The new infrastructure solution will cater to the continued expansion of the campus to new sites, and will also allow for the adoption of new technologies such as wireless LAN access and Voice over IP (VoIP).
