Consider sending real-time voice from Host A to Host B over a packet-switched network (VolP). Host A converts analog voice to a digital 112 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 28 kbps and its propagation delay is 20 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)? The delay until decoding time = ? msec

QUESTION 26 Suppose two packets arrive to two different input ports of a router at exactly the same time. Also suppose there are no other packets anywhere in the router. Suppose the two packets are to be forwarded to the different output port. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses a crossbar? True False QUESTION 27 UDP is a not reliable transfer protocol. True False QUESTION 28 Circuit switching allows more utilization than packet switching True False QUESTION 29 POP3 runs on top UDP? True False QUESTION 30 TCP is a secure protocol? True False
Consider the GBN protocol with a sender window size of 4 and a sequence number rangeof 1,024. Suppose that at time t, the next in-order packet that the receiver is expecting has asequence number of k. Assume that the medium does not reorder messages. Answer thefollowing questions: What are all possible values of the ACK field in all possible messages currently propagating back to the sender at time t? Justify your answer.
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?
Consider sending a file of F bits over a path of Q links. Each link transmits at R bits per second (bps). The network is lightly loaded so that there are no queueing delays. When a form of packet switching is used, the F bits are broken up into packets, each packet with L bits, of which h bits of it are header. Propagation delay is negligible. Let F = 5x104, Q = 20, R = 1 Mbps, L = 1000, and h = 10. b) Suppose the network is a packet-switched datagram network and a connectionless service is used. How long does it take to send the file?
Consider a scenario in which Host A wants to simultaneously send packets to Hosts B and C. A is connected to B and C via a broadcast channel—a packet sent by A is carried by the channel to both B and C. Suppose that the broadcast channel connecting A, B, and C can independently lose and corrupt packets (and so, for example, a packet sent from A might be correctly received by B, but not by C). Design a stop-and-wait-like error-control protocol for reliably transferring packets from A to B and C, such that A will not get new data from the upper layer until it knows that both B and C have correctly received the current packet. Give FSM descriptions of A and C.
Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hostsare 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.a. Express the propagation delay, dprop, in terms of m and s.b. Determine the transmission time of the packet, dtrans, in terms of L and R.c. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay.d. Suppose host A begins to transmit the packet at time t= 0, at time t =dtrans, where is the lastbit of the packet?e. Suppose dprop is greater than dtrans. At time t =dtrans, where is the first bit of the packet?
Consider a network with 4 links between two hosts where the maximum allowable packet size is 1000 bits; each link has a transmission rate of 2000 bits per second, except the second link has a transmission rate of 1000 bits per second. How long does it take to send 6000 bits from one host to the other? You may ignore propogation delay, assume there is no other traffic on the network, and assume that no routers drop packets due to queue length. Round your answer to two decimal places.
Consider this multihpop network running the 802.11 MAC protocol in ad-hoc mode (RTS-CTS-DATA-ACK) and a link speed of 1 Mbps: A === B === C === D Edges ‘===’ represent connectivity, so, for instance, nodes B and C can communicate with each other directly, but A and C cannot. All nodes are able to route packets on behalf of the other nodes and they employ store-and-forward to deliver packets to the destination. Suppose nodes A, B, and C have to send a lot of data frames to node D and have their link layer queue always full. What is the average data rate for A, B, and C assuming no DATA frames get lost due collisions? Explain your answer. Compare the data rates with the link rate.
Multiple packets may be sent between two hosts over a single connection. Could you please break down the timings for processing cargo? Is it to be anticipated that one delay would continue for a certain length of time while the other delay could be modified?
It is theoretically feasible for two hosts to communicate with one another by sending packets back and forth over the same connection. Please enumerate all of the components that are responsible for the overall amount of time required to process a single packet, starting to end. Is it to be anticipated that one of the delays will continue for a certain amount of time, while the duration of the other delay will be more unpredictable?
