The IPv4 datagram is conceptually divided into two pieces: the header and the payload .

The IP datagram structure Netanya Academic College

The datagram arrives at a gateway host wrapped in the local network header, the local network interface strips off this header, and turns the datagram over to the internet module....
The format of data that can be recognized by IP is called an IP datagram. It consists of two components, namely, the header and data, which need to be transmitted. The fields in the datagram, except the data, have specific roles to perform in the transmission of data. Every field in the IP datagram

header checksum does not match the contents, the datagram is discarded. Source IP Address: The 32-bit IP address of the host sending this datagram. Destination IP Address: The 32-bit IP address of the destination host for this datagram.

  • The Internet protocol Party time! IP 14-2 IPv4 datagram format IPv4 20 bytes no options (Plays a role similar to port numbers.) header + data length treats each two bytes of header as a number, adds and takes ones complement *Datagrams requiring low delay, high throughput, or reliability. Cisco interprets first 3 TOS bits as defining different levels of service that routers can provide. IP
  • The maximum IP datagram size is 4080 bytes, while a simple approach to IP datagram de-encapsulation could result in large parts of an MPE-FEC frame being erased, e.g., up to 4080 bytes for the maximum size datagram.
  • IP Datagram General Format (Page 1 of 3) The first 20 bytes are the fixed IP header, followed by an optional Options section, and a variable-length Data area. Note that the Type Of Service field is shown as originally defined in the IPv4 standard. Thats a pretty big table, because the IP datagram format is pretty important and has a lot of fields that need explaining. To keep it from
  • Now I do have the datagram format layout of IPv4 in front of me. The thing I don't understand is that in the solution it says that header length is 20bytes but according to the format the bits 4-7 correspond to header length which is 0x03c5 = 965 bytes. However, in the solution 965bytes is the total datagram
