Answer 1

Heya Friend,

In IPV4 when a datagram is encapsulated in frame the total size of the datagram must be less than the MTU(Maximum Transmission Unit).

Hope it helps...

Answer 2

In IPV4 when a datagram is encapsulated in frame the total size of the datagram must be less than the MTU(Maximum Transmission Unit).

What is the size of the total length field in IPv4 datagram?

• Total Length: Length of header + Data (16 bits), which has a minimum value 20 bytes and the maximum is 65,535 bytes.

What is the minimum size of an IPv4 datagram header in octets?

• The minimum size is 20 bytes (header without data) and the maximum is 65,535 bytes.
• All hosts are required to be able to reassemble datagrams of size up to 576 bytes, but most modern hosts handle much larger packets.
• Links may impose further restrictions on the packet size, in which case datagrams must be fragmented.

Which value that is contained in an IPv4 header field?

• The IPv4 header contains 13 fields.
• These fields are Version, Internet Header Length, Type of Service, Total Length, Identification, Flags, Fragment offset, Time-to-Live, Protocol, Header Checksum, Source address, Destination address, and Options.

What is identification in IPv4 header?

• The "Identification" field in the IPv4 header is a 16 bits field which indicates an identifying value assigned by the sender to aid in assembling the fragments of an IPv4 Datagram.
