Host A is sending data to host B over a full duplex link. A and B are using the sliding window protocol for flow control. The send and receive window sizes are 5 packets each. Data packets (sent only from A to B) are all 1000 bytes long and the transmission time for such a packet is 50 µs Acknowledgement packets (sent only from B to A) are very small and require negligible transmission time. The propagation delay over the link is 200 Us. What is the maximum achievable throughput in this communication? Discuss on design functionality of sliding window protocol.

Q.3
80. In a packet switching network, if the message size is 48 bytes and each packet contains a header of 3 bytes. If 24 packets are required to transmit the message, the packet size is ................ a. 2 bytes b. 1 byte c. 4 bytes d. 5 bytes
Using Direct Sequence Spread Spectrum, if the data message is 4 bits and the generated bit stream is 16 bits, the transmitted message over the link will be: O4 bits O 8 bits O 64 bits O 16 bits
Computer A is sending a 10 MByte long file to Computer B via packet-switching over two consecutive 100 Mbps links of 2000 km length each.Assume that the signal propagation speed on both links is 2 x 108 m/s.Furthermore, assume that the maximum length of a packet is 1480 bytes and that Computer A fills each packet to the max, if possible. How long (in seconds) does it take Computer A to send out one packet of maximum length on the first link?
1) Consider a packet of length 1200 bytes begins at end system 'A' and travels over three links to reach the destination end system 'B'. These three links are connected by two packet switches. Assuming no queuing delays, the propagation speed on all three links is 2.5*10 m/s, the transmission rates of all three links are 2 Mbps and the packet switch processing delay is 3 msec. Further, the length of the first link is 4,000 km, the length of the second link is 2,000 km, and the length of the last link is 3,000 km respectively. Specify the formula for total delay in this transmission and also calculate the end-to-end delay involved in this packet transmission?

How many bytes will be contained in the last packet?
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 seconds) does it take Computer A to send out one packet of maximum length on the first link?
What is the delay of sending a data file from a source station to a destination station? Suppose that the length of the data file is 2 Mbytes and the bandwidth of the channel is 1600 bps, and the network link between the sender and receiver is 20000 Km and the speed of the light inside the link is 2x108 meters/second? Assume that the delay is composed of only transmission time and propagation time.
I need the answer as soon as possible
Let us consider that there are two stations namely as X and Y. Station X uses 64-byte packet to transmit message to station Y using sliding window protocol The propagation delay between X and Y is 25 milliseconds and the bottleneck bandwidth on the path between A and B is 256 kbps. What is the optimal window size of X?
