Project Overview

You are working for a medium sized company, Foggy Solutions, that offerscloud-­-basedIT services including IaaS, PaaS, and SaaS, but also specialises in designing, developing, and delivering custom-­-builtsolutions for customers. The company currently has an office in the Melbourne CBD housing 60 staff consisting of:

Database Management


Virtualization Specialists


Solutions Developers




Level 1 Helpdesk








Unfortunately the space available in the existing office building has run out, and with the need to increase staff in the near future the company is investigating the feasibility of leasing space in another office building nearby. As one of the senior members of the Network Management staff, you have been appointed with the task of preparing a proposal for how the office space should be used.

Location and FacilityIssues

The map shown in Figure 1 illustrates the location and relative distances of the existing and new office buildings. The red shaded area indicates the location of the current office building, and the green shaded area indicates the location of the nearby building with available office space. The building containing the existing office space is leased entirely by Foggy Solutions, with the ground floor consisting primarily of sales staff and meeting spaces. The remaining staff are distributed between the basement (also containing the data centre) and the upperfloor.

The office space available in the nearby building is located on the upper floor, which is relatively the same height as the upper floor in the existing office space building. Each building has fixed windows (the windows don't open), and the owners of both properties will not permit any fixtures outside the building. Similarly, the local council will not permit any direct connection of cables between the buildings, either through overhead cabling or underground cabling. The new office space includes space for at least 30 staff and associated desk space, two meeting rooms (capable of hosting approximately eight people and a video conferencing system), and supporting facilities (tea/lunch room, toilets, etc.). The new office space would not be accessible to the public.

The local area, including both buildings, is reasonably covered by telecommunication providers, with both DSL connection to the local exchange (approximately one kilometre cable distance) and recently installed fibre optic connections through the NBN. Both services can be purchased through any ISPs that support it. The existing office space is already serviced by two redundant synchronous 10Mbps Internet connections, one provided by Telstra, and another provided by Optus, which are load balanced and peak utilisation reaches approximately45%.

The LAN in the existing building is designed according to the Cisco Enterprise Campus Architecture using a collapsed core. Six Cisco Catalyst 2960XR-­-24PD-­-I switches with redundant power supplies and form the access layer and two Cisco Catalyst WS-­-C3850-­-24T switches with redundant power supplies are used for the collapsed core/distribution layer. The data centre has its own dedicated network infrastructure, primarily consisting of Cisco Nexus series switches, however traffic entering/exiting the data centre is aggregated through two separate Catalyst 2960 switches identified above.

WAN connections gated through a Cisco 3945E router upgraded to the maximum 2GB DDR2 ECC DRAM and 2x4GB Compact Flash. The four on-­-boardGigabit Ethernet ports are all in use: two are used for LAN interconnection and two are used for the WAN connections identified above, however the service module, EHWIC, and DSP slots are allunused/free.

BGP is deployed to ensure connectivity from the external Internet is maintained in the case of one of the WAN connections experiencing an outage.

Project Requirements

Your employer has assigned you the task of preparing a formal proposal/plan for how this additional office space is to be used. Your employer has expressed the following requirements:

Redundant connectivity must be provided between the buildings using two different technologies, and an appropriate dynamic routing protocol selected to support the network structure;

You must identify which staff in the organisation should be moved to the new office space and must be reasonable/appropriate, e.g., reception staff must stay in the existing building where customers to receive customers entering from streetlevel;

Adequate bandwidth across the intra-­-buildinglinks must be provided for staff IT requirements in the new building, both for existing and staff that may be added in the future;

The organisation appoints different staff on an as-­-needed basis, so adequate space and bandwidth must be available for any type of staff member to be added in the new building in future;

Hardware requirements and approximate costs, both for establishing the new office space and ongoing costs, must be indicated (to be restricted to network infrastructure only);

Risks must be identified and appropriate countermeasures identified and included in the design of the network, and any implications for a disaster recovery plan must be appropriately disclosed and discussed.

Note: the marking scheme at the end of this question sheet provides further clarifications and expected sections in the report.

Staff Position Outlines

This section includes brief descriptions of each of the staff positions in the organisation. You will need this information when determining who could potentially be moved to the second office. All staff require access to basic office applications, technologies supporting collaboration and group work, e.g., file shares, intranet web sites, etc., and all staff have a VoIP telephone and can participate through video conferencing using a headset and webcam at their terminals through the organization's Cisco Unified Communications system.
