Question
Chapter 6, Problem R8RQ
Program Plan Intro
Token passing:
It is the access method where the token (signal) is passed among the nodes in order to approve those nodes to communicate.
Propagation delay:
It is nothing but the amount of time taken by the signal to travel from sender to receiver.

Students have asked these similar questions
Data collision occurs when multiple senders simultaneously attempt to access the communication medium. Various protocols have been developed to mitigate this issue. These protocols operate at different layers of the network stack. Could you please provide more specific information about the protocols you are interested in? Do these methods ensure reliable gearbox without any possibility of collisions? What alternative solutions are available if this approach proves ineffective?
(b) The Internet Protocol (IP) can sometimes surprise with its flexibility.
Since the overall design is close enough to the principles of the
OSI Protocol Model, IP is independent of the Data Link and
Physical network layers.
And some Norwegians indeed showed successful IP network
transmission is possible with carrier pigeons.
If we would want to attempt to use carrier pigeons to
establish a TCP connection between Canterbury and
London, how long would it take to successfully establish the
transmission under perfect conditions? (Assume the
pigeons are perfectly reliable.) Explain how you come to
your result.

In what situations can SSH come in handy? Is it OK to include SSHs in the list of protocols?

- For what kind of problems may SSH be a solution? Do we have permission to include SSHs in our list of protocols?arrow_forwardA 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?arrow_forwardIs there a range of situations where SSH may be useful? Should we exclude SSHs from our list of protocols, or is it fine?arrow_forward
- Transmittal protocols In the current state of network design, using both TCP and UPD has its pros and cons.arrow_forwardWhen it comes to transport layer protocols that can be relied on to provide services, TCP is a full duplex option.

- Why is it important for protocols configured on top of the Ethernet to have a length field in their header.arrow_forwardA 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.arrow_forwardA link has a transmission speed of 106 bits/sec. It uses data packets of size 1000 bytes each. Assume that the acknowledgment has negligible transmission delay, and that its propagation delay is the same as the data propagation delay. Also assume that the processing delays at nodes are negligible. The efficiency of the stop- and-wait protocol in this setup is exactly 25%.

- Consider a network with a ring topology, link bandwidths of 100 Mbps, and propagation speed 2 × 108 m/s. What would the circumference of the loop be to exactly contain one 1500-byte packet, assuming nodes do not introduce delay? What would the circumference be if there was a node every 100 m, and each node introduced 10 bits of delay?arrow_forward5)Consider a reliable data transfer protocol that uses only negative acknowledgments. Suppose the sender sends data only infrequently. Would a NAK-only protocol be preferable to a protocol that uses ACKS? Why? Now suppose the sender has a lot of data to send and the end-to-end connection experiences few losses. In this second case, would a NAK-only protocol be preferable to a protocol that uses ACKS? Why?arrow_forwardIP is a connectionless protocol, whereas TCP is connection-oriented. How can these two protocols live in the same stack the best manner possible?arrow_forward
