Topic: Network Delay Assume two hosts, A and B, that are linked by a single link with a rate of R bps and are spaced m meters away from one another. A packet of size L bits is being sent from Host A to Host B. Suppose that the propagation through the connection is occurring at s meters/second. (Answer the following question while showing work) 1) Assuming that processing and queuing delays are 0, provide an expression for end-to-end delay in terms of m, s, L, and R. 2) Where is the final bit of the packet at time t = dtrans if Host A starts transmission at time t = 0?
Suppose that we are sending a 30 Mb MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 × 108 meters/sec, and the distance between source and destination is 10,000 km. 1. Now suppose there is only one link between source and destination, and there are 10 FDM channels in the link. The MP3 file is sent over one of the channels. What is the end-to-end delay?
- Stations in a slotted Aloha network send frames of size 2000 bits at the rate of 1 Mbps. What is the vulnerable time for this network? - Explain why collision is an issue in random access protocols but not in controlled access protocols. - In a bus CSMD network with a data rate of 10 Mbps, a collision occurs 20 μs after the first bit of the frame leaves the sending station. What should the length of the frame be so that the sender can detect the collision?
A TCP PDU of length 40,513 octets (including the TCP header) is to be transmitted over a physical link between two nodes at 1,064,218,818 bps using 802.3 with an MTU of 826 octets. Assume a LLC-PDU has an overhead of 4 octets and that the IP-PDU has no options. i) How many bits are sent over the connection from the source to destination assuming only full frames are sent? ii) What is the effective data rate from the TCP-PDU point of view (to nearest integer)? iii) If the propagation time between the two nodes is 5 microseconds what is the line efficiency to 3 decimal places assuming stop and wait is used between the two nodes?
QUESTION 1 Consider a router buffer preceding an outbound link that has a transmission capacity of 100 packets/second. Assume that the router is operating in a steady-state with no packet losses. Suppose packets arrive at the router an average rate of 80 packets/second to use the outbound link. Calculate the following values. The traffic intensity is A packet uses the outbound link for seconds. The average delay (queuing and transmission) experienced by a packet is seconds. The average number of packets in the router waiting to use or using the outbound link is
In selective repeat ARQ, packet size is 2000 bytes transmission time for one packet is 1ms. If distance between hosts is 10km and signal speed is 4ms per km (4ms/km) and frame sequence number are 6 bit long in frame format then the throughput (in Mbps) is
2. Consider a bus-topology network with five stations. A reservation access method is used. Each station has infinite data to transmit. Each reservation slot has 10 microseconds (note that 1 microsecond = 106 second). For each station, one data transmission sends 1000 bits. The transmission rate over the medium is 10 Mbps. For a station, which is its throughput (in unit "Mbps")?
Consider a TCP connection with the following parameters: a) Initial ssthreshold = 8 b) Round Trip Time (RTT) = 10 milliseconds c) Retransmission Timeout period = 40 milliseconds d) Segment size = 2700 bytes The TCP connection was used to transfer 19 data segments, numbered 1 through 19. While sending the segments, data segment 10 was lost the first time it was sent (but arrived at the receiver properly upon being retransmitted). There were no other segment losses apart from the aforementioned. Assume that data segments received out-of-order are buffered at the receiver. What is the average throughput obtained in sending all the data segments (in bytes/sec)? Draw a diagram to show the transmission of the segments in detail.
Computer A is sending a 100 kByte long file to Computer B via packet-switching over two consecutive 10 Mbps links of 1000 km length each.Assume that the signal propagation speed on both links is 2.5 x 108 m/s.Furthermore, assume that the maximum length of a packet is 1500 bytes and that Computer A fills each packet to the max, if possible. How "long" (in meters) is one bit on link 1?
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. The previous expert did the wrong question and the answer was incorrect. The 3rd packet is lost not the 2nd packet
COMPUTING THE ONE-HOP TRANSMISSION DELAY Consider the figure below, in which a single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link.
