Question 9 Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 1,024 kbps, R2 = 2,048 kbps, and R3 = 10 Mbps. Assuming no other traffic in the network, how long (in seconds) will it take to transfer a 50 KiB file? Disregard propagation, processing, and queuing delays. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line
A connection between two servers may transport multiple packets simultaneously. Please break down for me how much time is consumed on each phase of goods processing. Should the duration of one delay be predetermined, while the duration of the other delay is situation-dependent?
Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are 100,000 bits long, and packets containing only control (e.g., ACK or handshaking) are 200 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Do you expect significant gains over the non-persistent case?

A large number of consecutive IP addresses are available starting at 198.16.0.0. Sup- pose that four organizations, A, B, C, and D, request 4000, 2000, 4000, and 8000 ad- dresses, respectively, and in that order. For each of these, give the first IP address as- signed, the last IP address assigned, and the mask in the w.x.y.z/s notation. A router has just received the following new IP addresses: 57.6.96.0/21, 57.6.104.0/21, 57.6.112.0/21, and 57.6.120.0/21. If all of them use the same outgoing line, can they be aggregated? If so, to what? If not, why not? The set of IP addresses from 29.18.0.0 to 19.18.128.255 has been aggregated to 29.18.0.0/17. However, there is a gap of 1024 unassigned addresses from 29.18.60.0 to 29.18.63.255 that are now suddenly assigned to a host using a different outgoing line. Is it now necessary to split up the aggregate address into its constituent blocks, add the new block to the table, and then see if any reaggregation is possible? If not, what can be…
Consider a slotted ALOHA network with three nodes that always have packets to send. Suppose one of the nodes requires a mean throughput of at least 0.3 packets per slot, and that it contends for slots with probability 0.45. Suppose that one of the other nodes contends for slots with probability 0.1. What is the maximum contention probability for the third node, without violating the throughput requirement of the first node? Already answered but want a detailed answer. Please don't copy paste
For the sake of this example, let's assume that a packet is being sent from its point of origin to an address at the other end of the network via the fixed route. The different delays-causing variables are also listed below: How many of the overall delays are time-dependent, and what proportion of the total delays are continuous for how long?
1.4.12.2 End-to-end Delay. Consider again the network shown above. The links again have transmission rates of R1 = R2 = 100 Mbps (i.e., 100 x 106 bits per second), and each packet is 1 Mbit (106 bits) in size. Assume that the propagation delay is 1 msec per link. What is the end-to-end delay of a packet from when it first begins transmission at the sender, until it is received in full by the server at the end of the rightmost link. Assume store-and forward packet transmission. You can assume the queueing delay is zero. Answer choices: A. 2 x 106 msec b. 2.01 msec C. 1.1 msec D. 2.02 msec 1.4.12.3 Maximum Throughput. Consider again the network shown above. The links again have transmission rates of R1 = R2 = 100 Mbps Assume that the link R2 is fairly shared (as we've seen is done via TCP) between the two sessions. What is the maximum end-to-end throughput achieve by each session, assuming both sessions are sending at the maximum rate possible? Answer choices:…
2. Question; Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B. Express the propagation delay, ????? , in terms of m and s. Determine the transmission time of the packet, ?????? , in terms of L and R. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay. Suppose , ? = 2?10^8 ?/?, ? = 5 ????? and ? = 100???? Find the distance m so that ????? equals ??????.
Consider a packet being sent from node A to node D in the network below using flooding, with a hop count of 3. How many copies of the packet are generated in each hop?
Please dont copy your answer from other sourses i.e chegg A communication line capable of transmitting at a rate of 50 Kbits/secwill be used to accommodate 10 sessions each generating Poisson traffic at a rate 150 packets/min.Packet length are exponentially distributed with mean 1000 bits. For each session, find the averagenumber of packets in queue, the average number in the system, and the average delay per packetwhen the line is allocated to the sessions by using: i) 10 equal-capacity time-division multiplexed channels;ii) statistical multiplexing.
Under the assumption of no packets loss, how long will it take TCP to send an object that is 20KB over a link with a RTT of 400 milliseconds, a MSS of 2KB, and a rate of 10KB/second when: a. TCP is in slow start, CongWin = 1 and Threshold = 10: b. TCP is in congestion avoidance, CongWin = 5 and Threshold = 5
Consider the following diagram: A,B,C and D are subnets, R1, R2, and R3 are routers. Default signifies theentire rest of the internet. All 4 subnets each contain the same number of hosts.Consider the following routing table at R3: CIDR Mask Link 0.0.0.0/0 L4 128.4.6.0/24 L3 128.4.8.0/24 L5 1. If 128.4.6.0 is in A, what is the routing table at R1? 2. The ISP that owns all these networks is short on IP addresses, so theyuse a NAT router for R2. How many public IP addresses will C andD use together assuming they use as many private 10.X IP addresses asthey can? How many total public IP addresses will be used by the entirenetwork? Why doesn’t the ISP care about how many private IP addressesare used? 3. Fix R3’s routing table now that we are using NAT: 4. A node in C is given the IP address 10.0.0.1 and only sends and receivespackets on port 1234. A packet destined for this node reaches R2 witha source of (IP=128.4.6.6, Port=3000) and destination of (IP=128.4.8.0,Port=10000).…
