Subway Organization: Detailed Network System and Cost Analysis

This report provides a detailed analysis of the network systems and associated costs within the Subway organization, a prominent fast-food franchise in Australia. It examines the LAN network design employed at the headquarters in Melbourne, emphasizing the use of IEEE 802.11 protocol and regulated packet flow. The report identifies key components such as DS-3E0105P-E for Differentiated Service, wireless routers as Access Points, and the implementation of Basic Service Set (BSS) and Extended Service Set (ESS) for network mobility. Furthermore, it details the network devices used, including computers, wireless routers, and modems, along with the range of radio frequencies and cable types (Cat 5e, Cat 6, and Cat 6a) utilized across different office sizes. The cost analysis underscores the efficiency of the network design in reducing costs and delays in data transmission, attributing this to the use of advanced networking devices. The report concludes that the investment in networking has positively impacted the organization's operations and recommends continued use of high-quality, updated networking devices, along with the implementation of security software solutions to protect against cyber threats. It references academic sources to support its findings and recommendations.

1. Introduction
Subway organization is one of the biggest well-known fast food franchises in Australia
operating in various regions in the country by supplying a range of foods such as the fresh meat,
fruits, and all various raw and already prepared foods2. It has the headquarters in Melbourne
where it comprises of well-trained IT professionals who ensure the operations of various offices
are well functioning. The report will aim at analyzing the network systems and its components in
Subway organization that has in turn led to the overall success of the organization.
2. Findings
2.1 Network Design and Flow Plan
The organization uses the LAN network design since the head offices are constructed
such that they are all located in one small geographical area. The network channel uses the IEEE
802.11 protocol due to the wide range of frequency it offers to the network. Also, the flow of the
packet at each edge is regulated by a certain capacity such that it cannot exceed the given
capacity. The organization packet flow involves sending and receiving the packets from one
point to the other.

2.2 ADS, AP, BSS and ESS Information
The DS-3E0105P-E is used in the network switch as their Differentiated Service (DS)
since it requires no configuration. Wireless built-in routers are used as a networking Access
Point, and it also uses some network cables that connect a close internal office device. An Access
Point is connected to the wired networks within the wireless network terming it as Basic Service
Set (BSS)1. Moreover, there are more than two BSS in the organization that forms a single
subnet to provide an extension of a range of mobility to the network packets. This is referred to
as the Extended Service Set (ESS).
2.3 Used devices, range, frequency, IEEE substandard
Computers and wireless routers are part of the network devices used in the organization.
Modems are present as a backup solution in case of the wireless routers functionality issue. The
WLAN channel used offers a range of radio frequency; 4, 5, 5.9 and 60 GHz. Cat 5e and Cat 6
are used for smaller offices (offers up to 100MHz and 250MHz) while Cat 6a is used in bigger
offices (offers up to 500MHz).
2.4 Cos Analysis
The network design has been a crucial part in reducing the cost and the delay time in
packet transfer and also communication within and outside the organization. The networking
devices are most advanced ensuring fast data transmission thus, generally, reducing the cost as
compared to the use of outdated network devices.

3. Conclusion
The investment in networking has boosted the organization operation, therefore, creating
a positive image for the employees and their customers. Use of the updated network devices has
ensured a continuous information flow from one point to another.
4. Recommendation
To ensure continued success in its production, the organization should keep on using the
latest networking devices which have been tested to be of high-quality output. Additionally, it is
recommended for the organization to consider the use of security software solutions and other
practices within the offices that ensure the office information is out of any attacks.
