Suppose the following HDLC sequence bits are transmitted on a link. Show the resulting sequence of bits with removed bit stuffing. 1101 0111 1101 0111 1100 1011 1110 110 the network transmission channel bit error rate is 0.00001, and each packet's total length is 1024 bytes including all overheads. Assume there are no other overheads, and assume the channel error model is random error model (i.e. errors could happen anywhere with equal probability). For each data packet transmitted over this error-prone channel. what is the Packet Error Rate (PER) for each single round of packet delivery? If one ARQ retry is applied, (i.e. total rounds of transmissions are 2. including I initial transmission, and I additional retry), what is the final average probability of packet error
