please answer the question clearly.
Sliding window protocol with window size of 7 frames are used between the data link layers of machines A and B. Assume that machine B sends an ACK (acknowledgement) for every frame it receives without error, and it sends a NAK (negative acknowledgement) for every frame it receives with error. This corresponds to a receiver window size of 1 frame. Assume also that no frames are lost in the transmission medium. For the scenario shown...

Data communications requires at least two devices working together, one to send and one to receive. Data Link Layer are responsible for creating frames, flow control and error control. In the transmission of frame, we can have four situations: normal operation, the frame is lost, the acknowledgment is lost, or the acknowledgment is delayed. For the above reason, FRAMES from a sending station are numbered sequentially. Find the explanation of Stop-And-Wait ARQ of data link control. Please answer this question...

(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...

The question has parts: a,b,c,d and e.
Intro. To Telecommunications Assign#4 (d) Suppose the same situation as above but sender and receiver use Selective Repeat ARQ What frame(s) would the sender need to retransmit? Explain. 1. Suppose that a sender and a receiver are using ARQ to perform reliable data delivery. (a) In a Go-Back-N ARQ protocol, the window size is 6. Frames with sequence numbers 1, 2, 3, 4 and 5 have been sent. The sender just received an...

(a) Assume a Sliding Window with Go-Back N ARQ is being used on a transmission link with a 3-bit sequence number. The transmitter has previously sent frames with sequence numbers 0, 1 and 2. Is the transmitter allowed to send a frame with sequence number 3 if the frame with sequence number 2 has not been acknowledged? Explain your answer. (b) Assume a Sliding Window with Go-Back N ARQ is being used on a transmission link with a 3-bit sequence...

1. A bit string, 011111101111101111110, needs to be transmitted at the data link layer. What is the string actually transmitted after bit stuffing? Underline the additional bits you insert. 2. When should a selective repeat protocol be used versus a go-back-n protocol. 3. Specify the fields that make up a Point-to-Point protocol [PPP] frame. 4. Provides a simple parametric formula to quantify the size [in bytes] of a PPP frame. 5. A 100-km-long cable runs at the T1 data rate....

1. For TCP end-to-end flow control, suppose the capacity of the
receiver buffer is 10 packets. Suppose the packets that are being
queued in the receiver buffer are packets 4, 5, 6, 7, 8, 10, 11.
What is the advertised window size the receiver sent to the sender?
Suppose packet 12 is the last packet sent by the sender. What’s the
effective window size at the sender? Can the sender send out packet
13 at this moment? How about packet...

In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...
