Chapter 1, Problem P17P

a.

Explanation of Solution

Let the number of nodes present in the transmission is Q.

Delayofend-to-end=nodenumbernumberofnodes(Processingdelay+Transmissiondelay+Propagationdelay)

Transmissiondelay=LengthofthenodeTransmissionrateofthelink

If L be length of the node and Rq be the transmission rate of the qth link then,

Transmissiondelay=

b.

Explanation of Solution

Let the number of nodes present in the transmission is Q.

Delayofend-to-end=nodenumbernumberofnodes(Processingdelay+Transmissiondelay+Propagationdelay+Average queuing delay)

Transmissiondelay=LengthofthenodeTransmissionrateofthelink

If L be length of the node and Rq be the transmission rate of the qth link then,

Choose the correct statment(s) from the following. A. It is possible to design a broadcast algorithm for ring interconnect network with time complexity O(logp)O(log⁡p), where p is the number of nodes in the ring. B. The time complexity of broadcast in bus interconnect network is O(1)O(1). C. It is possible to design a broadcast algorithm for hypercube interconnect network with time complexity O(logp)O(log⁡p), where p is the number of nodes in the ring. D. The time complexity of broadcast in ring interconnect network is O(1)O(1).
2. Consider a bus-topology network with five stations. A reservation access method is used. Each station has infinite data to transmit. Each reservation slot has 10 microseconds (note that 1 microsecond = 106 second). For each station, one data transmission sends 1000 bits. The transmission rate over the medium is 10 Mbps. For a station, which is its throughput (in unit "Mbps")?
Unless specified otherwise, use the free space propagation speed of light 3x108 m/s to calculate the propagation delay. For numerical calculations, the results must show the appropriate unit. Show a complete solution for each problem3. Consider a digital multimedia transmission system. Separate audio and video coders are used to encode these signals. Audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 2,000 bytes long, which includes a 48-byte header. The system generates one packet every 40 ms. Calculate the following values:a. The minimum data transmission rate required to support the above system.b. The minimum signal-to-noise ratio (SNR) in dB required to transmit the above audio and video information. Assume a 400-kHz transmission channel bandwidth is used.c. The end-to-end packet delay over a 50-km link, using answer in Part a).
