Computer Network
Let host X sends a file a size of 1500 byte to host Y through routers R1, R2, R3 and R4 respectively in two different ways. Each packet contains 100 bytes of header information along with the user data. Assume that the bandwidth of each link is 107 B/s ... difference between the time taken to send the packet in first case and the time taken to send the packet in second case in μs?

MTU question from computer networks
Consider an IP packet with a length of 4,500 bytes that includes a 20-byte IPv4 header and a 40-byte TCP header. The packet is forwarded to an IPv4 router that supports a Maximum Transmission Unit (MTU) of 600 bytes. Assume that the length ... fragment will be 600 Bytes. The last fragment size will be 468 Bytes. The fragment offset in the second fragment is 144.

Self doubt CN
In the connection termination phase, suppose the FIN segment from the client-side contains data ranging from sequence no 100 to 200, So will the ACK no from the server start from 201 or 202? Will the FIN flag consume 1 extra sequence number at the end, ... context of my question, will that sequence number be 99, before the beginning of the data segment or 201, after the data segment

ISI-PCB-2015-C1-b
A $64000$-byte message is to be transmitted over a $2$-hop path in a store-and-forward packet-switching network. The network limits packets toa maximum size of $2032$ bytes including a $32$-byte header. The trans-mission lines in the network are error free and have a speed of $50$ ... answer as $1*3*(T_t+T_p) + \;31*T_t$ where $T_t=0.325\; ms$ and $T_p=3.333\; ms$. Please Confirm.

# CN TCP connection establishment doubt about MSS
Say Client buffer is of 12000 Bytes and MSS is 1200 B and this info is sent to server and now server send the info in (SYN +ACK) segment as Server Buffer = 18000 B and MSS is 600 B Now in data transfer phase does both Client and ... 1200, 600) = 600 Bytes? Or does the sever will send 1200 Bytes segments to C and C sends 600 B segments to server?

MAC address, IP address, transmission of packet from one point to another.
I was studying how the packet is transmitted from source to destination, what i understood is, we need IP address to identify the network in which our destination is present, while MAC address (data link layer address) ... .com/change-mac-address-in-windows). How is it possible if MAC address is present in the NIC?

Maximum Segment Size (MSS in TCP) vs Maximum Transmissible Unit (MTU in Data Link)
It is known that any network can only transmit data packet size equal to (or less than) MTU allowed in the network. If that is the case, and if we have a Path MTU discovery in place, why is ... ) than MTU, will only burden Network Layer with fragmentation overhead. Is there any significant advantage of using MSS ?
