The bandwith utilization processing script is made up of three modules:

The models module contains the class NetworkBandwidthUtil, which captures the expected information from the netbitrate.csv and create a self-contained object from which the network_interface_name is calculated. This allows for straightforward data association for later output; each object contains the information necessary for each output row.

The process module contains three main functions:

create_network_interfaces takes the path of the bandwidth.csv file and parses through the file, creating unique keys in a dict that match the network interface name (derived from each parsed row's server + interface_name). The value associated with each key is the netbitrate included in each row. It is assumed that network interfaces are unique, and as such, if a duplicate were to be found in a row, it would override the previous netbit rate. The dict of network_interfaces is returned

calculate_network_bandwidth_utilization takes in the path of the netbitrate.csv and the dict returned from create_network_interfaces. It iterates over the csv file and creates a NetWorkbadnwidthUtil object for each row, storing the information from each row in the appropriate object property. It uses the object's calculated interface name to check the network interfaces dict for that name, and if found, recalculates the object's stored net bit rate using the value from the dict. Each object is appendd to a list, which is returned at the end of the function

write_output takes in the list of calculated network bandwidth utilization objects as well as the path to the output file. It iterates over each object and writes a new row with the object's information, subsequently printing that object's data out as well

main.py is the entry point into the program. It sets the path files and imperatively calls the appropriate functions from process
