Discrete Mathematic Question: Pretend we are defining a new class of networks: 1 byte for network IDs and 1 byte for hostID. The definition of class A is: networkdID is : 0xxx-xxxx and the one byte (8 bits) hostID cannot contain all 0s and 1s. The definition of class B is: networkdID is : 10xx-xxxx and the one byte (8 bits) hostID cannot contain all 0s and 1s The definition of class C is: networkdID is : 110x-xxxx and the one byte (8 bits) hostID cannot contain all 0s and 1s. How many total IP addresses can we have with the above definition?
COMPUTER NETWORKS: Please solve with solutions and provide correct answer An application message is segmented into 20 packets, each of which is 1000-byte in size. Caculate the end-to-end delay for the message when the bit rate for any node is 1 Mbps, the optical path total distance is 2000-km, and the queuing and processing delays are 1-ms and 1-ms, respectively. There are 4 intermediate routers in the path, each of which uses the store-and-forward approach.
Consider a TCP connection with the following parameters: a) Initial ssthreshold = 4 segmentsb) Round Trip Time (RTT) = 10 millisecondsc) Timeout period = 40 millisecondsd) Segment size = 3900 bytesThe TCP connection was used to transfer 17 data segments. While sendingthe segments, data segment 7 and data segment 15 were lost the first timethey were sent (but arrived at the receiver properly when retransmitted).There were no other segment losses apart from the aforementioned. Assumethat data segments received out-of-order are buffered at the receiver. Whatis the average throughput obtained in sending all the data segments (inbytes/sec) including draw a diagram to show the communication process in detail.
6. Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b-bits) connection retrieves a 250 KB (B-bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user's access link is the bandwidth bottleneck for this connection. a. Approximately how long does it take for the page (including images) to appear on the user's screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network) How long does it take if the connection uses persistent HTTP (single connection)? b. c. Suppose that user's access router has a 4 MB buffer (B-byte) on the link from the router to the user. How much delay does this buffer add during periods when the buffer is full? d. Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does…
Consider the following virtual circuit network with three reserved virtual circuits: уC1: H1, А, С, Е, Н2 VC2: H3, A, F, D, H4 ус3: НЗ, А, F, D, E, H2 Host H4 Host H3 Нost H2 Host H1 Draw the routing table of router D and the routing table of router C. *you may design a table using the HTML editor or write the content of routing table record by record (record per line).
Suppose that TCP's current estimated values for the round trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 300 msec and 13 msec, respectively. Suppose that the next two measured RTTs are 330 msec and 240 msec respectively. We want to calculate TCP's RTT estimate, and the value of TCP's timeout interval. Note that given a new measured RTT, you should first compute devRTT, then estimatedRTT (the textbook incorrectly reverses those computations), and then (lastly) the timeout interval. Use the values of α = 0.125, β = 0.25.Following the newly measured RTT of 330 msec, what is the new value for devRTT in msec? [Note: round your answer to the nearest msec - enter an integer value, do not include any decimal places/point or any leading zeros, but keep your full resolution value of devRTT handy and use it in any later calculations you perform using devRTT.
