TCP users send packets with data and TCP header information. The header contains source, destination, and other variables. TCP header is processed at each network device during transmission. Data remains unchanged, but header details like IP address may change. Options Field in TCP Header The TCP header has an optional options field for enhancements. It can be 0-320 bits, depending on data offset size. Options field holds various types: maximum segment size, window scaling, timestamps, etc. This field shows total option length, including kind and length. Option-data field has option details like numerical value or timestamp. ... Read More
IPv4 is used for network communication. Data packets contain important info. The IPv4 header includes an options field for flexibility and control. The options field is optional and located between header length and type of service. Its presence depends on the value in the header length field. Options Field in IPv4 Header IPv4 header contains information about the source and destination of an IP packet. It also has other parameters that affect how packets are processed by routers and hosts. It consists of a fixed part of 20 bytes, followed by an optional part of up to 40 ... Read More
