- Consider a two-link network in which Host A has a 1 Mbps connection with a 10 ms propagation delay and the router has a 15 Mbps link with a 25 ms propagation delay. Host A sends Host B a 1500-byte packet. What is the packet transmission delay from the router to Host B (in milliseconds)?Consider sending real-time data from Host A to Host B over a packet-switched network. Host A takes an 8-bit measurement every millisecond, and Host A collects these into 64-byte packets. There is one link between Hosts A and B; its transmission rate is 5 Mbps, its propagation delay is 2 × 108 meters/sec, and its length is 3 km. As soon as Host A gathers a packet, it sends the packet to Host B. How much time elapses from the time that Host A begins to take the first measurement in a packet until the entire packet reaches Host B?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 1,500 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?
- Suppose that there are three inter-media nodes between Host 1 and Host 2, and the transmission rate of each link is 4.096 Mbps. The time of end-to-end circuit established is 0.5 second. How much seconds does it take to send a file of 8.192M byte from host H1 to host H2 over a packet-switched network?Computer Science Consider two hosts C & D connected by a point-to-point link with a data link rate of 10 Gb/s. The hosts are 2 km apart and the signal propagation speed is 2 × 108 m/s. Given the packet size is 500 bytes, how many packets can be in inflight from C to D?Let the two host X and Y connected via a packet switch with 107 bits per second links. Switch is placed at 50 km from X. X and Y are located at 100 Kilometer apart also the propagation speed along the link is 2 × 108 m/s. The switch begins forwarding a packet after 0.1 milliseconds it receives the packet. If 1000 bytes of File are needed to be transmitted and each packet size is 500 bytes, the time elapsed between the transmission of the first bit of data and the reception of the last bit of the data in millisecond is
- Consider a datagram network in which a packet travels through two switches S1 and S2 from source to destination. Packet experiences wait at each switch before it is forwarded. Transmission time, propagation time and wait time at each node is 3 ms, 1.5 ms, and 0.25 ms respectively. Find the total delay.Two hosts are connected by a single direct link. Link transfer the data at a rate of 107 bits/seconds. The distance between the two host is 5000 km and the propagation speed along the link is 2 x 105 kilometer per second. One host is sending a data of 10,000 bytes in a single packet to another host. Let T₁ be the transmission delay and Tp be the propagation delay. The difference between the propagation delay and the transmission delay in millisecond isCompare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. Suppose Host A sends 5 data segments to Host B, and the 3rd segment (sent from A) is lost. In the end, all 5 data segments have been correctly received by Host B. How many segments has Host A sent in total and how many ACKs has Host B sent in total? What are their sequence numbers? Answer this question for all three protocols. The previous expert did the wrong question and the answer was incorrect. The 3rd packet is lost not the 2nd packet
- Consider two hosts, A and B that are connected by a transmissions link of2.1 Mbps. Assume that packets are of length 2.0 Kb (Kilobits) and the length of the link is 100Km. a. What is the propagation delay from A to B, that is the amount of time from when the first bit of the packet is transmitted at A, until it is received at B? b. What is the transmission time of the packet at A (the time from when the first bit of the packet is sent into the wire and the time at which the last bit is sent into the wire). c. Suppose now that that length of the link is doubled. What is the propagation delay from A to B now and what is the transmission time? d. Now suppose that node C is connected to node B also by a 2 Mbps, 100 Km link. How long does it take from when the first bit is transmitted by A to when the last bit is received at C, assuming B operates in a store-and -forward manner?Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. Suppose Host A sends 5 data segments to Host B, and the 3rd segment (sent from A) is lost. In the end, all 5 data segments have been correctly received by Host B. How many segments has Host A sent in total and how many ACKs has Host B sent in total? What are their sequence numbers? Answer this question for all three protocols.Consider two hosts S and R connected directly by a link. A link has a transmission speed of 107 bits/sec. It uses data packets of size 400 bytes. Data needed to transmitted is 400 bytes. Length of the link is 600 km and the propagation speed are 3 × 108 meter per second. T is the transmission delay and P is the propagation delay. The propagation delay in millisecond and transmission delay in microsecond respectively are
