Would you make any recommendations to change the situation? Why or why not?Which of the following TCP congestion control mechanism defines only a linear growth rate in the number of segments sent to the receiver? BIC Congestion Avoidance Reno TCP Slow Start Taho TCPHosts A and B have a TCP connection with neither side having any unacknowledged data. Now, host A sends two TCP segments back to back to host B.

Write down all the important protocols that come into play by the time the first frame containing HTTP request reaches R1. (Note: Before HTTP frame, other frames have already been sent by other protocol(s).) Write down all the protocols with reference to the TCP Model as follows? Application Layer: Transport Layer: Internet Layer: Link Layer:True or false? Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over a TCP connection to Host B.
