1. Consider the HDLC protocol, that was configured for 8-bit address field and 16-bit FCS field. 1.1. Node-A is sending a frame containing the control field \( \boldsymbol{R} \boldsymbol{R} \mathbf{7}, \boldsymbol{P} \) and no other data. The receiver address is \( 1 \mathrm{E} \) hex, and we'll assume that the bits calculated for the FCS are BFFF-hex. Note: HDLC transmits the LSB first 1.2. How many bytes are in the HDLC frame before encoding 1.3. What is binary content of each Byte and what does it represent 1.4. Draw the HDLC bit-stream before bit-stuffing 1.5. Draw the HDLC bit-stream after bit stuffing 2. Consider a Stop-and-Wait protocol, for which, the time required for successful transmission of a frame is \( 1 \mathrm{~ms} \), successful meaning that the receiver gets the frame w/o errors, and that the sender gets the ACK. The retransmission timer is \( 2 \mathrm{~ms} \). The likelihood of successful frame transmission is \( 0.95 \). 2.1. Calculate the protocol efficiency for the above protocol configuration 2.2. Assuming that frames are 1,000 bit long, and considering the above efficiency, what is the throughput of the link (Mbps)
