Station A nee...

Question

Station A needs to send a message consisting of 9 packets to Station B using a siding window (window size 3) and go-back-n error control strategy. All packets are ready andimmediately available for transmission. If every $5^{t h}$ packet that A transmits gets lost(but no acks from B ever get lost), then what is the number of packets that A will transmit for sending the message to B?

Q. Station A uses 32 byte packets to transmit messages to Station B using a sliding window protocol. The round trip delay between A and B is 80 milliseconds and the bottleneck bandwidth on the path between A and B is 128 kbps. What is the optimal size that A should use ?

Q. Suppose that the maximum transmit window size for a TCP connection is 12000 bytes. Each packet consists of 2000 bytes. AT some point of time, the connection is in slow start phase with a current transmit window of 4000 bytes. Subsequently, the transmitter receives two acknowledgement. Assume that no packets are lost and there are no time-outs. What is the maximum possible value of the current transmit window?

Q. A 1 Mbps satellite link connects two ground stations. The altitude of the satellite is 36.504 km and speed of the signal is

3 \times 10^{3} m / s

. What should be the packet size for a channel utilization of 25% for a satellite link using go-back-127 sliding window protocol?

Assume that the acknowledgment packets are negligible in size and the there are no errors during communication.

Q. In a packet switching network, packets are routed form source to destination along a single path having two intermediate nodes. If the message size is 24 bytes and each packet contains a header of 3 bytes, then the optimum packet size is

Q. Consider three networks A,B and C. Host

H_{A}

in network A sends messages each containing 180 bytes of application data to a host

H_{C}

in network C. The TCP layer prefixes a 20 byte header to the message. This passes through an intermediate network B. The maximum packet size, including 20 byte IP header, in each network is
A: 1000 bytes
B: 100 bytes
C: 1000 bytes
The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps=bits per second)

Assuming that the packets are correctly delivered, how many bytes, including headers, are delivered to the IP layer at the destination for one application message, in the best case? Consider only data packets.
