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?

A link has a transmission speed of 1010 bits/sec. It uses data packets of size 2000 bytes each. The efficiency of the stop-and-wait protocol in this setup is exactly 30%. Determine the value of the one-way propagation delay in milliseconds. Assume that the acknowledgement has negligibletransmission delay, and its propagation delay is the same as the data propagation delay. Consider the same transmission speed and packet size for Go back-N protocol with window size 8 and find the channel utilization.
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?
Consider a two-link network in which Host A has a 1 Mbps connection with a 10 ms propagation delay and the router has a 15 Mbps link with a 25 ms propagation delay. Host A sends Host B a 1500-byte packet. What is the packet transmission delay from the router to Host B (in milliseconds)?

X and Y are located at 100 Kilometer apart also the propagation speed along the link is 2 × 108 m/s. The switch begins forwarding a packet after 0.1 milliseconds it receives the packet. If 1000 bytes of File are needed to be transmitted and each packet size is 500 bytes, the time elapsed between the transmission of the first bit of data and the reception of the last bit of the data in millisecond is

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. Show the steps used for derivation in detail. 70,000 bps 70,000 bps 70,000 bps 70,000 bps 70,000 bps KJ Router 1 Router 2 Router 3 Router 4 ТА
