Tcp congestion control – consider sending a large file from one host to another over a tcp connection that has no loss. a) suppose tcp uses aimd for its congestion control without slow start. assuming cwnd increases by 1 mss every time a batch of acks is received, and assuming constant round-trip times, how long does it take for cwnd to increase from 1 mss to 6 mss? b) what is the average throughput (in terms of mss and rtt) for this connection up through time = 5rtt?

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
