Computer Networks And Internet Protocol - Week 5 Assignment 5 | NPTEL | JAN 2023

Computer networks and internet protocol - week 5 | assignment 5 : answer with explanation.

Which of the following is true?

d. UDP doesn't have any flow control, congestion control No flow control, no congestion control

SOCK STREAM represents

b. TCP-based Stream Socket Stream Socket (SOCK STREAM): Reliable, connection oriented (TCP based)

FD_ZERO is used for

b. Initializes the file descriptor set fd_set — a bitmap of fixed size FD_ZERO: Initializes the file descriptor set fd_set – a bitmap of fixed size

Which statement (s) is/are true for Slow Start

b. The rate of increase in the congestion window is very slow

Sender Window in TCP can be given as:

d. Sender Window = min(Congestion Window, Receiver Window)

Socket Address is:

b. Combination of IP Address and Port Address In computer networking, a socket address is a combination of an IP address and a port number that uniquely identifies a particular network service on a host. It is used by the Transport Layer protocols, such as TCP and UDP, to establish a connection between two endpoints on a network. The IP address identifies the host where the service is running, while the port number identifies the specific service or application running on that host. For example, the socket address "192.168.1.100:80" specifies that the service running on the host with IP address 192.168.1.100 is listening on port number 80, which is typically used for HTTP traffic. Socket addresses are important for establishing network connections, as they provide a way for applications to communicate with each other over the network. They are typically represented as a string in the format "IP address:port number", and can be used by both client and server applications to establish a connection and exchange data.

Which of the following uses UDP?

a. DNS DNS (Domain Name System) uses UDP (User Datagram Protocol) as its transport protocol. UDP is a simple, connectionless protocol that doesn't provide error checking or reliability, but is well-suited for applications like DNS that require low latency and fast transmission of small packets.

When you create a socket as s = socket(domain, type, protocol), why do you set the value of the protocol parameter as zero?

a. The system selects the default protocol number for the domain and socket type requested When creating a socket using the socket() function, the protocol parameter specifies the protocol to be used by the socket. However, for most applications, it is not necessary to specify a particular protocol, and the operating system can choose an appropriate protocol based on the specified domain and socket type.

select() system call returns zero when?

b. This means the call timed out without any event ready for the sockets monitored -1: Means an error was encountered, you should do something about it. I just print the error 0: Means the call timed out without any event ready for the sockets monitored >0: Is the number of sockets that have events pending (read, write, exception)

In TCP congestion control mechanism is triggered once

b. After a Retransmission Timeout(RTO) c. 3 Duplicate ACK(DUPACK) is received Two ways to trigger a congestion notification in TCP – (1) RTO, (2) Duplicate ACK. THREE duplicate ACKs (DUPACKs) imply that a packet has been lost – triggers congestion control mechanism
