Hema A Murthy. Indian Institute of Technology Madras. IP Packet Format. • Version: Version of protocol the DG belongs to (IPV 4,. IPV6). • IHL – Header length in 32 bit words. – minimum - 5,. – maximum – 60. • TOS – 3 bit precedence, three flag D, T,R, unused bits. (Delay, Thruput, reliability). • Total length – Header + data.
course looking here at IP version 4 and so we will examine the IPv4 datagram format, which was defined in RFC 791 along Even though IP is a relatively simple, connectionless, “unreliable" protocol, the IPv4 header carries a fair bit of information, See below for the longer explanation of TTL. Table 57: Internet Protocol
Routing is based on destination address. • TTL (time to live) decremented at each hop (avoids loops). • Fragmentation used for large packets. - Fragmented in network if links crossed with smaller MTU. - MF bit means more fragments for this IP packet. - DF bit says “don't fragment" (returns error to sender). • Almost always
The entire network still appears as one IP network to the outside world. Thus, a host within a network that has subnets is aware of the subnetting structure. A host in a different network is not. This remote host still regards the local part (subnet + host) of the IP address as a host number.
16 Feb 2009 Version: IP version 6. • Traffic Class: used in congestion control. • Flow Label: QoS management. • Payload length: payload length in bytes. • Next header: specifies the next encapsulated protocol. • Hop Limit: replaces the ttl field of IPv4. • Source and Destination addresses: 128 bits each
IPv4 Header Fields. • Version: IP Version. • 4 for IPv4. • HLen: Header Length. • 32-bit words (typically 5). • TOS: Type of Service. • Priority information. • Length: Packet Length. • Bytes (including header). • Header format can change with versions. • First byte identifies version. • Length field limits packets to 65,535 bytes.

IPv4 Header. Header Checksum. Checksum of entire IP header. Header Length. Number of 32-bit words in. TCP header
Options integrated in header fields. Options supported with extensions headers (simpler header format). Figures 1 and 2 compare the header of a IPv4 packet and an IPv6 packet. Even if you don't study packet header fields, you can see the difference between the IPv4 header. (fragmentation fields are italicized) and the
For example, an IP address of one computer is 192.168.1.2. Another computer might have the address 128.10.2.1. This is called the dotted decimal format. Ipv4 Header: Version:(4 bits): Indicates the version number, to allow evolution of the protocol. Internet Header Lenght(IHL 4 bits): Length of header in 32 bit words.
The IPv4 packet header consists of 14 fields, of which 13 are required. The 14th field is optional and aptly named: options. The fields in the header are packed with the most significant byte first (big endian), and for the diagram and discussion, the most significant bits are considered to come first (MSB 0 bit numbering).
