Give some details of how you might augment the sliding window protocol with flow control by having ACKs carry additional information that reduces the SWS as the receiver runs out of buffer space. Illustrate your protocol with a timeline for a transmission; assume the initial SWS and RWS are 4, the link speed is instantaneous, and the receiver can free buffers at the rate of one per second (i.e., the receiver is the bottleneck). Show what happens at T = 0, T = 1,..., T = 4 seconds.

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

Question

Give some details of how you might augment the sliding window
protocol with flow control by having ACKs carry additional
information that reduces the SWS as the receiver runs out of
buffer space. Illustrate your protocol with a timeline for a
transmission; assume the initial SWS and RWS are 4, the link
speed is instantaneous, and the receiver can free buffers at the
rate of one per second (i.e., the receiver is the bottleneck). Show
what happens at T = 0, T = 1, ..., T = 4 seconds.

The message to be sent from source to destination is 4000B. The link MTU's from source to destination are 1500, 1000, and 750. If we DO NOT use Path MTU, what are the respective fragment sizes to be reassembled? If we DO use Path MTU, what are the respective fragment sizes to be reassembled?

6. Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b-bits) connection retrieves a 250 KB (B-bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user's access link is the bandwidth bottleneck for this connection. a. Approximately how long does it take for the page (including images) to appear on the user's screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network) How long does it take if the connection uses persistent HTTP (single connection)? b. c. Suppose that user's access router has a 4 MB buffer (B-byte) on the link from the router to the user. How much delay does this buffer add during periods when the buffer is full? d. Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does…

4. In this problem, you will derive the efficiency of a CSMA/CD-like multiple access protocol. In this protocol, time is slotted and all adapters are synchronized to the slots. Unlike slotted ALOHA, however, the length of a slot (in seconds) is much less than a frame time (the time to transmit a frame). Let S be the length of a slot. Suppose all frames are of
