Question

if(node is 1 and tick and num_pkts_sent < num_pkts[node])

Answer 1

pkt = (PKT_PTR) malloc(sizeof(PKT));

pkt->type = DATA;

pkt->seq_no = seq_no ++;

pkt->source = 1;

pkt->dest = 2;

pkt->size = 10;

sendm(sink,0,pkt); line_busy = 1;

receivedata= 0;

pkt = (PKT_PTR) malloc(sizeof(PKT));

pkt->type = ACK;

pkt->seq_no = seq_no ++;

pkt->source = 3;

pkt->dest = 1;

pkt->size = 10;

sendm(sink,0,pkt);

line_busy = 1;

ack=0;
