Transport Layer

A leaky bucket with the capacity of a bucket of 200 MB is at the host network interface. The data rate on the network is 4 Mbyte per sec. If the host has 400 Mbytes to send onto the network and it sends the data in a burst, then the maximum data speed from the host in order that no data is lost is ___ in MBps [in integer]

Consider the following statements regarding sockets and sockets API.

S₁: Sockets allow communication between two different processes on the same or different machines.

S₂: The client, after the creation of a socket, uses the connect( ) system call to establish a new TCP connection.

S₃: The server uses a bind( ) system call to bind the socket to an address.

S₄: The server uses a listen() system call to accept a connection.

Which of the above statements are correct?

Suppose that the TCP entity receives a 3-megabyte file from the application layer and the IP layer is willing to carry blocks of a maximum size of 2000 bytes. The amount of overhead incurred from segmenting the file into packet sized units is :

Note: The size of the IP header and TCP header is 20 bytes.

Consider the effect of using additive increase multiplicative decrease (AIMD) on a line with a propagation delay of 10 ms. Consider the initial threshold is 24 KB and the maximum segment size is 2 KB. The time out occurs at the 7^th transmission and P is the congestion window size at the start of the 7^th transmission, Q is the congestion window size at the start of the 10^th transmission. Compute the value of P + Q in KB ?

Which of the following does UDP not guarantee?
