system using the Stop-and-Wait ARQ Protocol has a time-out of 6ms and round trip time RTT is 4ms. Assume the acknowledgment of first frame is delayed by 4ms and the third frame is received in error one time. All other frames and acknowledgement are received correctly .Dra

What are the unique characteristics that differentiate the synchronous real-time paradigm from other paradigms?

Given that the current value of RTT(S) (.e., the smoothed round-trip-time) is 14 ms, and given that a new segment is sent and acknowledged and has a measured RRT of 17 ms. What is the new value of RTT(S)? Show your calculations.

The fundamental distinctions between synchronous and isochronous connections will be explicated, and an instance of each will be presented.

3. Computer A tries to send 6 frames to computer B. The second frame does not arrive correctly (assumed to be lost). Draw the flow diagram using Stop-and-wait ARQ protocol and assuming that the round trip delay is 3 ms and the system time out is 6 ms.

Write an 8051 asm program to send a welcome message "Warm Welcome" serially. Whenever the INT1 has a high to low transition the following message is to be sent serially "Guest Approaching". Assume baud rate of 19200 and XTAL = 11.0592 MHz

Explain the operation of simplex stop and wait protocol.

. Show using diagram the contents of the six output frames for a synchronous TDM multiplexer that combines four sources sending the following characters. Note that the characters are sent in the same order that they are typed. The third source is silent. Source 1 message: SUMMER b. Source 2 message: DATA c. Source 3 message: d. Source 4 message: CSE

Give an example of a synchronous connection and one of an isochronous connection, and explain what sets them different.

If the state diagram of Stop and Wait ARQ at the sender and receiver site are given below, the states have value of (Sn, Rn), the arows shows the transitions. According to the figure, explain the events labeled A, B, C, and D. A 0,1 1,0 В D 1,0 0,1 A- BI
