According to the given figure, assume that, PC0 wants to send a message to PC4. If the distance between the two points is 22,000 km, 3.2-kbyte message sends in 2.4 x 100000000 mls speed through cable and the transmission link has 1.5 Gbps Bandwidth. When the message arrives at Routers , Router0 already has 4 packets to process in the queue and each will need 2ms. Router1 has no packets in the queue, but if it had then would require 3ms to process. Router2 already has 5 packets to process in the queue and each will need 1ms. Calculate the total time to send the message from PC0 to PC4.

Assume now that between A and B there is a switch S that uses store and forward. The distance from A to S is m meters and from S to B 2m meters. The link speed between A and S is R bps and between S and B R/2 bps. A has a supply of 6 packets to send to B using UDP. The switch buffer can accommodate 3 packets including the one being transmitted (until it finishes its transmission). Will there be packet losses at the switch buffer. Which packets (number packets 1, 2, 3, ...). Draw an annotated time-space diagram to illustrate this data transmission. (you should roughly respect the scales in your drawing).

Suppose that Router A and Router B are connected via a 0.05 Mbps link (note, 1 Mbps = 106 bps) and that the link connecting the two routers has a length of 80 meters. Suppose that Router A is in the process oftransmitting a packet, and that there are 15 additional packets in the queue of the router, when a new packet arrives at Router A. Assume the followinga. Every packet consists of 15,000 bits.b. 5000 bits of the currently-being-transmitted packet has been transmitted by Router A when the new packet arrives at Router A. c. Propagation speed of a bit over the link connecting the two routersis 2 ? 103 meters/sec.d. Processing delay of a packet at a router takes 1 millisecond (i.e., 0.001 seconds).What is the total delay of the new packet in arriving at Router B, i.e., how long does it take the new packet to arrive at Router B from the time it arrived at Router A? In your solution, clearly identify all four delay components the new packet experiences.
A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,200 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?
In this problem, we consider sending real-time voice from Host A to Host B over a packet switched network (VoIP). Host A converts analog voice to a digital 64 kbps bit stream on the fly. Host A then groups the bits into 56-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps and its propagation delay is 10 msec. As soon as Host A gathers a packet, it sends it to Host B. As soon as Host B receives an entire packet, it converts the packet's bits to an analog signal. How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)?
Suppose that KJ sends 3596 back-to-back packets, with each packet composed of 14,000 bits, to TA over 5 links (shown below). Suppose that the transmission rate of each link is 70,000 bits/sec (bps). Consider the routers to be store-and-forward routers. In such a scenario, find the endto- end delay of sending all the packets to TA (i.e., the time needed for the last bit of the last packet to arrive at TA since KJ starts transmitting the first bit of the first packet). Note, consider only the transmission delay that occurs in sending packets in your analysis. Show the steps used for derivation in detail. 70,000 bps 70,000 bps 70,000 bps 70,000 bps 70,000 bps KJ Router 1 Router 2 Router 3 Router 4 ТА
The maximum packet size (Maximum Transmission Unit or MTU) of an IP packet including IPv4 header on 100 Mbps Ethernet is usually set at 1500 bytes. A typical IPv4 header consists of 20 bytes, and a UDP header consists of 8 bytes. If we split up a file of 20,000,000 bytes so we can send it as a series of UDP payloads, how many IP packets do we have to send in order to transfer the entire file? Enter an integer number without formatting (no commas). Answer:
Consider the scenario below where 4 TCP senders are connected to 4 receivers. The servers transmit to the receiving hosts at the fastest rate possible (i.e., at the rate at which the bottleneck link between a server and its destination is operating at 100% utilization, and is fairly shared among the connections passing through that link). R =1 Gbps and Rc is 300 Mbps and Rs is 400 Mbps. And that all four senders have data to send, What is the minimum value of Re that will ensure that the connections to Host-1 and Host-2 are not bottlenecked at links with capacity Rc or Re?
2. In the figure below, Host A has a UDP Echo client while Host B has a UDP Echo server. The UDP Echo Client at Host A sends a message of size 100 Bytes to the UDP Echo server at Host B, and Host B echoes the same message back to Host A. Please measure the round trip time it would take for Host A to receive back the message it sends to Host B. Hosts A and B are connected using a Router R1 and links L1 and L2. The links, L1 and L2, have link transmission rates of 1 Mbps and 1 Mbps respectively. Assume that the router has a queuing delay of 1 milliseconds and a processing delay of 0.05 milliseconds. Assume that propagation delay is 0. Please state your response in accuracy of 6 decimal points. i.e., your response should have up to 6 places after the decimal.
