A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are take

n in the steady state for this system with the following results:
Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits

The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.

Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?

Answer:

a) 15.24 kbps

b) 762 bits

Explanation:

Using little law

a) Determine the average arrival rate (  λ  ) in units of packets/s

λ  = r / Tr  --- 1

where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 ))  = 0.0656

back to equation 1

λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps

b) Determine average number of packets <em>w</em> to be served

w =  λ * Tw =  15243.9 * 0.05 = 762.195 ≈ 762 bits

Write a function named repeat_words that takes two string parameters: 1. in_file: the name of an input file that exists before r
madam [21]

Answer:

#section 1

def repeat_words(firstFile, secondFile):

   infile_1=open(firstFile,'r')

   content1=infile_1.read()

   infile_1.close()

#section 2

   import string

   newContent=""

   for char in content1:

       newContent+=char.strip(string.punctuation)

   newContent=newContent.lower()

   newContent=newContent.split()

#section 3

   repeated_list=[]

   for word in newContent:

       if newContent.count(word)>1:

           repeated_list.append(word)

#section 4

   new_repeat_list=[]

   for item in repeated_list:

      while item not in new_repeat_list:

         new_repeat_list.append(item)

#section 5

   outfile=open(secondFile,'w')

   for repeat in new_repeat_list:

       outfile.write(repeat)

       outfile.write('\n')

   outfile.close()

   infile_2=open(secondFile,'r')

   content2=secondFile.read()

   infile_2.close()

   return content2

# section 6

in_file = 'aa.txt'

out_file = 'cpu.txt'

print(repeat_words(in_file, out_file))

Explanation:

#section 1

it defines a function that takes two arguments. It opens the first argument in the read mode and stores all it's content in a string variable "content1". finally the file is closed.

#section 2

In this section the string module is imported which allows for easy manipulation of string variables.

A new string variable is created that would store the already stripped file.

<em>strip(string.punctuation)  </em>strips every character of any leading or trialing punctuation.

<em>lower()  </em>converts string to lover case.

<em>split() </em>converts a string to an array of sub-string, i.e an array of words.

#section 3

This section collects all the words in the array and places them in a list.

#section 4

Utilizes a For and a While loop to ensure that no word repeats and stores it in a new list.

#section 5

Opens a new file and writes all the content into that new file and then closes the file.

re-opens the file, reads and returns the content of the file.

# section 6

This is added in order to test the function and print the result

I used your question to test the function and attached the result.

cheers!

How many bits are used to direct traffic to specific services running on a networked computer?
Mars2501 [29]

Answer:

The correct answer is 16 bit.

Explanation:  

The main role of the transport layer provided the communication channel of the process which are running in a different host. When the information flows there is always traffic that is arisen but the transport layer aimed is that process will go at the correct node and received at the proper destination. The 16-bit number specifies that the process or node is running in the networked traffic.
