Berkeley sockets originated with the 4.2BSD Unix operating system, released in 1983, as a programming interface.Not until 1989, however, could the University of California, Berkeley release versions of the operating system and networking library free from the licensing constraints of AT&T Corporation's proprietary Unix.

After instantiating a new socket, the server binds the socket to an address. For a Unix domain socket, the address is a /path/filename.. Because the socket address may be either a /path/filename or an IP_address:Port_number, the socket application programming interface requires the address to first be set into a structure.
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header.It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
Flags: 8 bits Contains 8 1-bit flags (control bits) as follows: CWR: 1 bit Congestion window reduced (CWR) flag is set by the sending host to indicate that it received a TCP segment with the ECE flag set and had responded in congestion control mechanism. [22] [a] ECE: 1 bit ECN-Echo has a dual role, depending on the value of the SYN flag. It ...
Scapy is a packet manipulation tool for computer networks, [3] [4] originally written in Python by Philippe Biondi. It can forge or decode packets, send them on the wire, capture them, and match requests and replies. It can also handle tasks like scanning, tracerouting, probing, unit tests, attacks, and network discovery.
RFC 791 describes the procedure for IP fragmentation, and transmission and reassembly of IP packets. [1] RFC 815 describes a simplified reassembly algorithm. [2] The Identification field along with the foreign and local internet address and the protocol ID, and Fragment offset field along with Don't Fragment and More Fragments flags in the IP header are used for fragmentation and reassembly of ...
