You have been consulted to design the computer network for a new restaurant nearby where you live. The

company operating the restaurant already runs three similar restaurants across the city; this new fourth

restaurant will be largest one in the chain, and also be the new base of the company. The owners have

taken this opportunity to fully incorporate IT and networking operations into their business. With a

guarantee of over $200$ customers per hour during peak periods, the restaurant has seating for dine$-$in

customers as well as fulfilling takeaway orders $($ordered online, via phone and as walk$-$ins$).$ To achieve this,

all equipment and terminals in the restaurant will be networked to allow automation and real$-$time

information retrieval. This includes: cooking appliances, fridges and freezers, coffee machines, customer

self$-$ordering consoles, service staff consoles, Point$-$of$-$Sale registers, various printers, and information

display screens $($e$.$g$.$ for displaying menus and specials$).$ Customers and service staff will use WiFi$-$enabled

tablets for viewing menus and ordering. At the rear of the restaurant will be the new head office of the

company, which includes facilities for business administration $($marketing$,$ finance, CEO, etc.$),$ staff area for

relaxation and meetings equipped with networked entertainment consoles, as well as a training kitchen.

There is also a storage facility, with WiFi$-$enabled tags and scanners to keep track of supplies. All systems

will be networked and integrated with the various restaurant and business software systems, e$.$g$.,$

purchasing, stock tracking, sales, marketing, accounting, payroll, staff information, customer information

and rewards. During peak operation periods as many as $40$ service staff may be working in the restaurant.

In addition, there are $15$ to $20$ staff working in the office area on a daily basis.

While the company will use cloud services for some servers $($e$.$g$.,$ website, email$),$ they will continue to use

local servers in the office building for important information $($e$.$g$.,$ sales, customer information and

finances, which are important intellectual property for the company$).$

The company will install IP$-$based security cameras around and inside the buildings for security purposes.

They will stream video back to a local server in the office for storage and security monitoring. The company

plans to provide free Wi$-$Fi for dine$-$in customers $($as well as to all staff$).$

The company requires at least three different IP subnets, one for the main dining and service area, one for

the office and one for the security cameras. However more subnets may be used if justified. The company

requires the use of $/24$ and$/$or $/16$ network masks throughout $($no other masks are allowed by the

company$).$

You have been consulted to design the network for the new restaurant $($the other three restaurants are

NOT included in the project$).$ The owner wants to see the design and hear your inputs on a variety of issues

$($including cyber security and cloud services$).$ Then the owner will decide whether to further engage your

services for the network build, operation and maintenance.
