GO Classes Test Series 2024 | Mock GATE | Test 14 | Question: 11
Consider the following network, which consists of two routers (R1 and R2), two switches (S1 and S2), and four hosts (H1, H2, H3, and H4). Suppose H1 wants to send packet to H3, which of the following is ... address of R1 Packet leaving R1 will have destination mac address of R2 Packet leaving R2 will have destination mac address of S2

GO Classes Test Series 2024 | Mock GATE | Test 12 | Question: 35
Consider two TCP connections $\text{A}$ and $\text{B}:$ The RTT for connection $\text{A}$ is $100$ ms while the RTT for connection $\text{B}$ is $200$ ms. Let $\textsf{ssthresh}$ denote the threshold at which the congestion ... end up sending $65$ more packets than connection $\text{A}$ in interval $[\text{T}, \text{T}+1]$ seconds.

U = set-up time for circuit switch (seconds) Y = transmission delay per link (seconds) (also called “transfer delay”) L = message length (bits) >0 R = transmission rate (bits per second) >0 (also called “placement rate”) H = header size (bits) =>0 P = packet size (bits) >H (note that this is the total packet size, i.e. header + data) X = decision time per packet (also called “packet routing delay”) 1. If L=1000, Y=1, R=4000 and U=1, choose a value of X. What is the total transmission time in the circuit switch network and packet switched network? Consider P=125 and H=25. (3 marks)

Kurose and Ross Edition 6 Exercise 1 Question R20 (Page No 69)
Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets from the file. When one of these packets arrives at a packet switch, what ... Why is packet switching on the Internet analogous to driving from one city to another and asking directions along the way?

Kurose and Ross Edition 6 Exercise 1 Question R11 (Page No 68)
Suppose there is exactly one packet switch between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 and R2, respectively. ... -to-end delay to send a packet of length L? (Ignore queuing, propagation delay, and processing delay.)

#MADE_EASY_WORKBOOK
Suppose that $x$ bits of user data are to be transmitted over $k-$hop path in a packet-switched network as a series of packets each containing $p$ data bits and $h$ header bits with $x>>(p+h)$. The bit rate of lines is $b$ bps and propagation delay is negligible.What is ... $(p+h)x/pb \hspace{0.1cm} bits$ $px/b \hspace{0.1cm} bits$ $hx/pb \hspace{0.1cm} bits$
