Question

Python

Design a class named IP_address to represent IP address objects. The IP_addressclass contains the following

• A number of instance variables/fields to store a table of data. You can design them on your own.
• A constructor that creates a table with the following:
  • a list of data.
  • IP address
  • an integer to indicate the number of elements in the sum_list/freq_list/average_list
• A get_ip_address() method that returns the IP address

For example, consider the following code fragment:

ip_key = '192.168.0.24'
data_list =[(0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84), (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84), (20, 84)]
size = 3
ip = IP_address(key, data_list, size)

The data_list contains a list of tuple objects. Each tuple consists of the time-period value and the packet-size. You should summarize this list and create a frequency list, a sum of the packet-size list and an average of the packet-size list. There are a lot of data for each time-period value. We calculate the total number of bytes that the source host sent for each 10-second interval. For example, the above data_list will be divided into 3 groups, such as (0-9 second), (10-19 second) and (20-29 second)

• (0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84)
• (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84)
• (20, 84)

Therefore, the IP_address object should contain:

• the IP address: '192.168.0.24

This will give

ip_key = '192.168.0.24' data_list =[(0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84), (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84), (20, 84)] size = 3 ip = IP_address(ip_key, data_list, size) print(ip.get_ip_address())

192.168.0.24

And

• modify the constructor and create the sum of the packet-size list
• add a method named get_sum_list(). The get_sum_list() method return a list of the sum of packet-size lists (i.e. if the sum list is [840, 840, 84], then the get_sum_list() should return [[0, 840], [1, 840], [2, 84]]

For example, consider the following code fragment:

ip_key = '192.168.0.24'
data_list =[(0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84), (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84), (20, 84)]
size = 3
ip = IP_address(key, data_list, size)

The data_list contains a list of tuple objects.

• (0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84)
• (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84)
• (20, 84)

Therefore, the ip object should contain:

• ip address: '192.168.0.24
• a sum of packet-size list: [840, 840, 84]

For example:

Test	Result
ip_key = '192.168.0.24' data_list =[(0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84), (10, 84), (11, 84), (12, 84), (13, 84), (14, 84), (15, 84), (16, 84), (17, 84), (18, 84), (19, 84), (20, 84)] size = 3 ip = IP_address(ip_key, data_list, size) print(ip.get_sum_list())	[[0, 840], [1, 840], [2, 84]]

Python code:

class IP_address:
    #Construct IP class
    def __init__(self, ip_key, data_list, size):
        super(IP_address, self).__init__()
        self.ip_key = ip_key
        self.data_list = data_list
        self.size = size

    #To get avg
    def avg(self, lst):
        return int(sum(lst) / len(lst))

    #To get IP key
    def get_ip_address(self):
        return self.ip_key

    def filterBy(self):
        stop = self.size * 10
        ranges = [(n, min(n+10, stop)-1) for n in range(0, stop, 10)]
        freq_data = []
        for i, r in enumerate(ranges):
            freq_data.append((i,[item for item in self.data_list if r[0] <= item[0] <= r[1]]))
        return freq_data

    #To get sum of list
    def get_sum_list(self):
        #interval 10 secs
        packets = self.filterBy()
        return [(size,sum([p[1] for p in packs])) for size, packs in packets]

#Input datas
ip_key = '192.168.0.24'
data_list = [(33, 60), (34, 64), (34, 1500), (34, 712), (35, 52), (35, 60), (36, 52), (36, 287), (37, 52), (37, 52), (37, 52), (39, 60), (40, 643), (40, 52)]
size = 5

ip = IP_address(ip_key, data_list, size)
print("==============IP Key===================")
print(ip_key)
print("==============Data list===================")
print(data_list)
print("==============Size===================")
print(size)
print("==============IP address===================")
print(ip.get_ip_address())
print("==============List of the sum of packet-size list====================")
print(ip.get_sum_list())

output:
