Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

Question

The distance from Earth to Mars is about 90 * 106 meters in the
best case (the exact distance depends on the relative orbital
positions of the two planets and can be much more). Assume there
is a link between Earth and Mars with a transmission rate of
2Mb/s. We need to send a packet from Earth to Mars over this link,
and the packet has a length of 3000 bits.
(Recall: light speed is 3,000,000 meters/sec)
1. What's the transmit delay ?
2. What's the propagation delay?
3. Ignore queuing and processing delay, what's the end-to-end
delay?

Host A is sending data to host Bover 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. Acknowledgment packets (sent only from B to A) are very small and require negligible transmission time. The propagation delay over the link is 200 µs. What is the maximum achievable throughput in this communication?
Computer Science Consider the slotted ALOHA protocol with (N+M) devices. N devices transmit with access probability p, and the other M devices transmit with access probability q. Find the throughput of this system, expressed in terms of packet/slot. Explain your answer.
In the GO back N sliding window protocol the value of N is 70% of the factor 'a: Where 'a' is the ratio of propagation time to the transmission time. The efficiency of GBN is 30 %. What will be the transmission time in a micro sec of the protocol where the length of the channel is 900 m and the speed on which signal propagates is similar to the speed of light in a vacuum?

The network propagation speed is 200,000 kilometers/second. Host A sends 10,000- bit packets to Host B. Give proper units on each answer. (For these and other nu- merical problems it is required that you give a formula, using numbers from the problem, that can be evaluated to give the numerical answer.) a) What is the round-trip propagation delay between A and B? b) What is the transmission delay of a single packet from A to B? c) What is the bandwidth-delay product between A and B (RTT)?
Suppose that KJ sends 3596 back-to-back packets, with each packet composed of 14,000 bits, to TA over 5 links (shown below). Suppose that the transmission rate of each link is 70,000 bits/sec (bps). Consider the routers to be store-and-forward routers. In such a scenario, find the endto- end delay of sending all the packets to TA (i.e., the time needed for the last bit of the last packet to arrive at TA since KJ starts transmitting the first bit of the first packet). Note, consider only the transmission delay that occurs in sending packets in your analysis.
