In which of the following phase of the TCP congestion control algorithm, the size of the congestion window increases additively?

The transport layer protocols used for SMTP, TFTP, Telnet, SNMP and FTP respectively are:

Consider a receive in a sliding window protocol uses of 6 bits window length. What is the sequence number of one hundred and eighty frame?

Assume Sequence number starts with 0.

Consider a TCP session for which the bandwidth is 4 Gbps. TCP session starts with a hexadecimal number BCAF. What is the minimum time in seconds before BCAF sequence number can be used again?

Which of the following is TRUE about three way handshaking?

I. The client sends the first segment, SYN segment along with window size.

II. The server sends the second segment, a SYN + ACK segment with two flag bits set: SYN and ACK.

III. The server sends the third segment, ACK segment. It consumes one sequence number.

Consider a client has established TCP connection with a server and sending data. The propagation delay is 5 ms and there are no timeouts and errors during transmission. The size of the receiver advertised window is 128 KB, the slow-start threshold at the client is 64 KB, and the maximum segment size is 4 KB. The connection is established at time T = 10 ms. What is the size of the congestion window (in KB) at time 90 ms after all acknowledgements are processed?

Consider a host, sending 2000 bytes of data in a TCP connection. The first byte is numbered as 12345 in decimal. If the data is divided into 7 segments in which the first 6 segments are equal data each and the last segment is having 500 bytes of data. Find the sum of last byte number of 6^th segment and 7^th segment?

Consider the following statements about socket API functions.

I. Bind() converts an unconnected active TCP socket into a passive socket.

II. Listen() waits for incoming connections.

III. Accept() is used to associate a socket with a port on the local machine.

Which of the above statements are incorrect?

A host machine uses the token bucket for congestion control with a capacity of 9 GB and the maximum output rate is 250 MBps. The minimum time required to transmit the data is 50 seconds. Tokens arrive to sustain output at a rate of x MBps per second. Find the value of x.
