Chapter 1, Problem R11RQ
Explanation of Solution
- The transmission rate between sending host and switch is termed as R1 and between switch and receiving host is termed as R2.
- At time t0, the sending host initiates the transmission.
- At time t1 = L/R1, the sending host will transfer all the data to the switch or the router...

We send real-time voice from Host A to Host B over a packet-switched network (VolP). Host A converts analog voice to a disital
64 Kbps bitstream on the fly then groups the bits into 64-byte packets. As soon as Host A gathers a packet, it sends it to Host R
(Obviously a data packet must be generated first before any bit inside it can be transmitted).
There is one link between Hosts A and B; its transmission rate is 10 Mbps and its propagation delay is 10 msec.
As soon as Host B receives an entire packet, it converts the packet's bits to an analog signal
How much time (in milliseconds) elapses from the time a bit is created from the original analog signal at Host A) until the bis
arrived at Host B and gets decodedas part of the analog signal at Host B)?
Hint Calculate the time to generate a packet of 648 time to transmit this packettime to propagate
Your aewwer should only contain umbers rounded to the hundredth (For example 123 S)
Prvious
Consider two systems P and Q connected via a
router R with the bandwidth of 2 Gbps. The
length of the packet is 1000 bytes. The
propagation delay between P and Q is 200
microseconds. The distance between the P and
R is 10 km while the distance between R and Q
is 5 km. The propagation speed in meter per
second if each link is having the same
10³ km/s?
propagation speed is
A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,200 bytes and the link rate is 2 Mbps.
What is the queuing delay for the packet?
More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?

- A sender with window size (W=3) is connected to a selective repeat receiver by a link with bandwidth =106 bytes/second and propagation delay of 0.25 msec. The receiver sends Positive ACK for correctly received packets. For each packet sent, the sender sets a timer with time out value of 5 msec. On receiving an ack for a packet, the timer for that packet is cancelled. If the timer expires, that packet is retransmitted immediately. Assume that the sender sends packets 1, 2, and 3 (at t=0, packet size =1000 Bytes) and packet 2 is lost. NO other packet is lost. Under this scheme , at what time in msec would all the packets been received at the receiver.arrow_forwardConsider a router buffer preceding an outbound link. In this problem, you will use Little’s formula, a famous formula from queuing theory. Let N denote the average number of packets in the buffer plus the packet being transmitted. Let a denote the rate of packets arriving at the link. Let d denote the average total delay (i.e., the queuing delay plus the transmission delay) experienced by a packet. Little’s formula is N=a⋅d . Suppose that on average, the buffer contains 10 packets, and the average packet queuing delay is 10 msec. The link’s transmission rate is 100 packets/sec. Using Little’s formula, what is the average packet arrival rate, assuming there is no packet loss?arrow_forwardConsider a datagram network using 32-bit host addresses. Suppose a router has four links, numbered 0 through 3, and packets are to be forwarded to the link interfaces as follows: Destination Address Range Link Interface 11100000 00000000 00000000 00000000 through 11100000 00111111 1111111 11111111 11100000 01000000 00000000 00000000 through 11100000 01000000 1111111111111111 11100000 01000001 00000000 00000000 through 11100001 01111111 11111111 11111111 otherwise 0 1 2 3 a.

- A sender with window size (W=3) is connected to a go back N receiver by a link with bandwidth =106 bytes/second and propagation delay of 0.25 msec. The receiver sends Positive ACK for correctly received in order packets. For each packet sent, the sender sets a timer with time out value of 5 msec. On receiving an ack for that packet, the timer is cancelled. If the timer expires, that packet is retransmitted immediately.

- 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?arrow_forwardIt is theoretically feasible for two hosts to communicate with one another by sending packets back and forth over the same connection. Please enumerate all of the components that are responsible for the overall amount of time required to process a single packet, starting to end. Is it to be anticipated that one of the delays will continue for a certain amount of time, while the duration of the other delay will be more unpredictable?arrow_forwardTCP / IP uses the client-server communication model, in which a user or computer (a client) receives a service (such as sending a web page) from another computer (a server) on the network. In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously. Answer the following questions briefly. How does resource reservation work in the TCP / IP model? Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model? What protocol assigns an IP address to the client connected to the Internet? Checksum is used by various protocols on the Internet, but not at the one of TCP / IP Explain.arrow_forward
- Don't try to copy others. Send unique answer only.arrow_forwardConsider four Internet hosts, each with a TCP session. These four TCP sessions share a common bottleneck link - all packet loss on the end-to-end paths for these four sessions occurs at just this one link. The bottleneck link has a transmission rate of R. The round trip times, RTT, for all fours hosts to their destinations are approximately the same. No other sessions are currently using this link. The four sessions have been running for a long time. i) What is the approximate throughput of each of these four TCP sessions? Explain your answer briefly. ii) What is the approximate size of the TCP window at each of these hosts? Explain briefly how you arrived at this answer.arrow_forwardConsider a long-lived TCP session with an end- to-end bandwidth of 1 Gbps (= 10⁹ bits-per- second).
