dont answer by copying from other sources I want accurate answer I will downvote for sure if the answer is from other source or internet. Suppose that in a packet-switched VoIP network, Host A sends real-time voice to Host B. Host A converts analog voice to a digital 512 kbps bit stream on the fly. Host A then groups the bits into 256 byte packets. There is one link between Host A and B; its transmission rate is 12 Mbps and its propagation delay is 15 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 that 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)

Skype is a well‑known VoIP system used not only for peer‑to‑peer conversations but also for audio and video conferencing involving three or more callers. Assume a video conference with a central server on Skype has N callers, and each caller generates a constant data stream at rate r bps. How many bits per second does the call initiator need to send? How many bits does each of other N‑1 callers need to send?
Computer A uses the Go-back-N ARQ protocol to send a 110 Mbytes file to computer B with a window size of 15. Given each frame carries 100K bytes data. How long does it take to send the whole file (the total time taken from A sending the first bit of the file until A receiving the last acknowledgment)? Given that the transmission rate of the link is 500 Mbps and the propagation time between A and B is 15ms. Assume no data or control frame is lost or damaged and ignore the overhead due to header and trailer.
We compress the video with the pattern GoP (16 : 3) by using MPEG coding. Assume that the average compression ratios of frame I, frame P, and frame B are 1:5, 1:20, and 1:60, respectively. We put the compressed frames in 512 B packets and send them. The header size of each packet is 5% of the size of packet. Each packet contains information on one frame and its header, Each frame can be sent in multiple packets. Picture resolution is 196 × 144 for a video at 32 fps. (a)What is the compression ratio in this pattern? (b)What is the order of coding and transmitting frames in this pattern? (c)If frame 6 is lost while transmission, which frames will be faulty?

Dont copy from any source I will downvote for sure Answer only if you have Keen knowledge or else will surely downvote. Consider a noiseless communication system over a transmission medium with transmission rate 10 bits/second. The Stop-and-Wait protocol is used. The distance between the sender and receiver is 60,000 meters, and the signal propagation speed is 3x108 meters/second. A data frame from the sender has 1000 bits, while an ACK frame from the receiver has 100 bits. What is the throughput of the system? Here throughput means on average how many bits of information per second can be delivered from the sender to the receiver

In this problem, we consider sending real-time voice from Host A to Host B over a packet-switched network (VoIP). Host A converts analog voice to a digital 64 kbps bit stream on the fly. Host A then groups the bits into 56-byte packets and when a packet is formed, it is send to host B. There is one link between Hosts A and B; its transmission rate is 2 Mbps and its propagation delay is 10 msec. What's the elapsed time since when the first bit is formed (from the original analog signal at Host A) until the bit is received at host B?
Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms

In a network, two systems are connected and the distance between the system is 5000 km. The propagation speed of the medium is 2 x 107 m/s. The bandwidth of the network is 500 MBps. If the average packet size is 108 bits and the network is used to its full capacity. The minimum size of the sequence number field is n bits. The processing delay at nodes is 0 ms. What is the value of n in case of Go-Back-N sliding window protocol?
Suppose that a 20-Mbps 802.11 LAN is transmitting 64-byte frames back-to-back over a radio channel with a bit error rate of 10−7 (i.e., the probability of a bit to flip duringthe transmission). How many frames per second will be damaged on average?(*hint: you would need to calculate the probability that a frame does not suffer any bit errors, thisis equivalent to the fraction of frames that do not suffer any bit errors on average.)
Consider a sender using a reliable data transfer protocol. The sender wants to send 9 packets to a receiver. The transmission delay for a single packet is 40 milliseconds. The propagation delay between the hosts is 100 milliseconds. Assume an ACK is small enough that you can ignore its transmission delay. You may also assume that no packets are lost, damaged, or reordered. For this question, a reliable data transfer is considered finished when all ACKs have been received by the sender. How long would this take using a pipelined reliable data transfer protocol with a window size of 6? In milliseconds How long would this take using a non-pipelined reliable data transfer protocol? In milliseconds
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? Justify and explain your answer.
