Error Control involves taking one of three actions: (1) Toss the frame/packet; (2) asking to resend he frame/packet that was in error; (3) correct the error without retransmission. Discuss the advantages/disadvantages for each of these scenarios. What is the single greatest advantage of having a checksum for only the IP header? Why is cyclic redundancy checksum (CRC) implemented for Ethernet and for wireless frames as an error control technique?
