Extracted text: The RDT 2.2 protocol. Consider the rdt 2.2 sender and receiver below, with FSM transitions labeled in red. Which of the following sequences of transitions could possibly occur as a result of an initial rdt_send( call at the sender (with no messages initially in the channel) , and possible later message corruption and subsequent error recovery? rdt_send(data) (so sndpkt -make_pkt (0, data,checksum) udt_send(sndpkt) rdt_rev(revpkt) (corrupt (revpkt)|| 1SACK (revpkt,1)) (S1) Wait for call 0 from above udt_send(andpkt) Wait for ACK O rdt_rev(revpkt) 6 notcorrupt(revpkt) 4 ISACK(revpkt, 1) rdt_rev(revpkt) & notcorrupt (revpkt) IBACK (revpkt,0) RDT 2.2 sender (S5) (S2) Wait for ACK 1 Wait for call 1 from above rdt_rev(revpkt) (corrupt (revpkt)|| ISACK ( revpkt,0)) S4) udt_send(sndpkt) rdt_send(data) (S3 sndpkt -make_pkt (1, data,checksum) udt_send(sndpkt) rdt_rev(revpkt) &6 notcorrupt (revpkt) 66 has seq0 (rcvpkt) RO extract (revpkt,data) deliver_data(data) sndpkt=make_pkt(ACK,0, checksum) udt_send( sndpkt) rdt_rev (revpkt ) 4 (corrupt(revpkt) || has sego(revpkt)) R1 andpkt-make_pkt(ACK,0,checksum) udt_send(sndpkt) rdt_rev (revpkt) s6 (corrupt (revpkt)|| has_seg1(revpkt)) sndpkt=make_pkt Wait for O from below RDT 2.2 Wait for 1 from R3 receiver below (ACK, 1, checks um) udt_send (sndpkt) rdt_rev (revpkt) && notcorrupt (revpkt) S6 has seq1(revpkt) (R2 extract (revpkt, data) deliver_data(data) sndpkt=make_pkt(ACK,1, checksum) udt_send( sndpkt)
