Typically the link layer encapsulates IP packets in frames with a CRC footer that detects most errors, many transport-layer protocols See more
WebMar 18, 2014 · Add a comment. 0. The initial 5 rows of the IP header are always used. So, minimum length of IP header = 5 x 4 bytes = 20 bytes. The size of the 6th row representing the Options field vary. The size of Options field can go up to 40 bytes. So, maximum length of IP header = 20 bytes + 40 bytes = 60 bytes. Share. WebThe minimum length is 8 bytes, the length of the header. The field size sets a theoretical limit of 65,535 bytes (8-byte header + 65,527 bytes of data) for a UDP datagram. However the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 bytes − 8-byte UDP header − 20-byte IP header).
