ICT System Design and Support - Network Architecture Design Report

This report details the design and implementation of an ICT network architecture for Western Sydney College (WSC). It encompasses the minutes of a meeting, review of specifications, stakeholder consultation, and objectives set by the IT manager. The technical requirements, including hardware (Cisco routers and switches, PCs, laptops, and printers) and software (operating systems, printing software, network analyzer, and database), are outlined. The report presents network designs for the main campus and preliminary designs for expanded networks across multiple campuses, along with an evaluation of preliminary design and performance, including network impact, traffic demands, and expected performance parameters. It details the finalized network design, network costs, and an evaluation report. The report also covers network performance review, training requirements, and technical specifications from vendors. The project culminates in a sign-off, confirming the successful completion of the ICT network design project. The report includes a bibliography of relevant sources.

6. I) Preparation for Main Campus Network Design
Figure 1: WSC Campus Network Architecture
The above figure shows how the six different departments of the institute WSC
obtains the network connection from main building. The network is shared among the staff
through the PCs, laptops and printers. Network of other campuses are expected to follow
similar layout.
II) Preliminary Network Design
The geographical expansion of the network of WSC Institute involves networks of
four campuses. Starting from the right is the main campus. The main campus is connected to
the interstate campus in Tasmania which is in turn connected with networks of campuses in
Parramatta and Sydney.

7. Network Impact
Out of the 254 IP addresses available from the major network 192.168.10.0/24, number of IP
addresses needed and allocated to the four subnets are 120
50% of the network address space from major network is getting used
100% of the sub-netted network address spaces are getting used

The inter network routing of the WSC network occurs through RIP version 2 dynamic
routing technique. This routing technique uses the Bellman-Ford algorithm and the path
selection here is hop based. The routing mode is observed to be classless with multicast
transmission. Other performance metrics of the routing technique are:
9. Expected Performance Parameters
Administrative distance: 120

8ICT SYSTEM DESIGN AND SUPPORT
Hop Count Limitation: 15
Authentication mechanism: MD5
Transmission protocol: UDP
10. Performance profile
Figure 2: Preliminary Design of WSC Expanded Network Coverage (Visio Screenshot)
The WAN performance is expected to be at par with the performance from networks
of each campus. This is because the network segments are more or less equidistant from
the interstate campus network that relays connections between different campuses.

III) Finalized Network Design and Approval
Figure 3: Finalized Design of WSC Expanded Network
The above figure implements the finalized network as per the specifications reviewed
earlier. This involves installing routers and switches to connect the end devices with the
campus network and then the campus network with that of other campuses.

12. Evaluation Report
The overall network of WSC covers network segments of main campus, interstate
campus at Tasmania and network segments of campuses at Sydney and Parramatta. The
different departments of each campus are isolated through VLANs. Inter network WAN
security is ensured by IPSec VPN. TCP/IP communications are secured through SSH
protocol.
13. Network Performance Review
Increased branching of networks from the routers can affect network performance.
Higher network connections from routers can require additional ports thereby increasing
costs.
These problems can be solved by introducing layer 3 switches which can reduce connection
load on routers and increase network security by enabling inter VLAN routing.
14. Training
Individuals need to become familiar with the latest operating system from Microsoft
and the printing and scanning application from Epson. Network engineers must be
comfortable to work with state of the art flat ethernet cables of cat7 specification. Network
administrators should not have issues using Wireshark protocol analyser.
