$$ Assignment

In this project, the learners should create a client$-$server system that exchanges information

about flights at a certain airport. The emphasis in this project is on client$/$server

architecture, network communication, multithreading, API, and applying good coding

practices.

The system should consist of two Python scripts $($the server and the client$).$ The server

should retrieve data of a selected airport from aviationstack.com via the proper API, extract

the required information from the retrieved data, manage connections with multiple

simultaneous clients, and respond to client requests.

The Server Script

The server should start by asking about the target airport $($ICAO code$)$ and retrieve the

information about flights at the specified airport over an API. Then the server should be

$2$

ready to handle the clients with their requests. It should extract the needed information

from the API response and send it to the client.

The server should conduct the following tasks:

$1.$ Once the server starts up$,$ it should ask the user to enter the airport code $($arr$\_$icao$).$

$2.$ Uses the proper API to retrieve $100$ records of flights at the specified airport $($use

avaitionstack.com$).$

$3.$ Store the retrieved data in a JSON file called "group$\_$ID$.$json" $($for testing and

evaluation purposes$)$

$4.$ Wait for clients' requests to connect $($should accept at least three connections

simultaneously$).$

a$.$ Accept the connection.

b$.$ Store the client$$s name and display it on the terminal.

$5.$ Wait for clients$$ requests, search the retrieved data for matching, and send a reply

with the matching information.

a$.$ All arrived flights $($return flight IATA code, departure airport name, arrival

time, arrival terminal number, and arrival gate$).$

b$.$ All delayed flights $($return flight IATA code, departure airport, original

departure time, the estimated time of arrival$),$ arrival terminal, delay, and

arrival gate.

c$.$ All flights from a specific airport using the airport ICAO code $($return flight

IATA code, departure airport, original departure time, estimated arrival

time, departure gate, arrival gate, and status$).$

d$.$ Details of a particular flight $($return flight IATA code; departure airport,

gate, and terminal; arrival airport, gate, and terminal; status; scheduled

departure time; and scheduled arrival time$).$

The server should display the following details clearly on the server screen:

$1.$ The acceptance of a new connection with the client$$s name.

$2.$ The requester name, type of request, and request parameters.

$3.$ The disconnection of a client with its name.

The Client Script

The client script should connect to the server and stay on until the user selects the Quit

option. The client should present multiple options for the user; different request types and

quit options. The client should send different types of requests, and receive and display the

responses. The client should be user$-$friendly and display the options and results neatly.

The client should stay connected and ready to send new requests until the user chooses to

quit.

$3$

The client program should conduct the following tasks:

$1.$ Establish a connection with the server and send the client$$s username to identify

itself.

$2.$ Sends one of the following four request types:

a$.$ Arrived flights: the client should display the flight code $($IATA$),$ departure

airport, arrival time, arrival terminal, and arrival gate.

b$.$ Delayed flights: the client should display the flight code $($IATA$),$ departure

airport, departure time, estimated arrival time, delay, terminal, and gate.

c$.$ All flights coming from a specific city: $($the client should display flight

code $($IATA$),$ departure airport, departure time, estimated arrival time,

departure gate, arrival gate, and status.

d$.$ Details of a particular flight: the client should display flight code $($IATA$),$

departure $($airport$,$ gate, and terminal$),$ arrival $($airport$,$ gate, and terminal$),$

status, scheduled departure time, and scheduled arrival time.

$3.$ Close the connection and leave when the user selects the Quit option.

Note: the retrieved information should be displayed clearly and neatly. Add a these concepts that we did not take in the class. learn it$,$ implement it in your code, and explain its

basics in your report:

$1.$ TSL$/$SSL $($security$)$: should secure all your packet transactions. Use

Wireshark to examine the exchanged packets. You must show that it is

working during the demonstration and include pieces of evidence in your

report $($screenshots of the packet data$).$

$2.$ Object$-$Oriented Programming: use object$-$oriented programming in your

coding. Describe, in your report, the basics of OO in Python, and your

classes.

$3.$ GUI: use a graphical user interface for the client. It should be easy to use

and clear to read. The user should send all requests using the GUI
