The TCP protocol is based on this socket type. SOCK_DGRAM Supports datagrams (connectionless, unreliable messages of a fixed maximum length). The UDP protocol is based on this socket type. SOCK_SEQPACKET Provides a sequenced, reliable, two-way connection-based data transmission path for datagrams of fixed maximum length; a consumer is required to read an entire packet with each read call. SOCK_RAW Provides raw network protocol access. This special type of socket can be used to manually construct any type of protocol. A common use for this socket type is to perform ICMP requests (like ping). SOCK_RDM Provides a reliable datagram layer that does not guarantee ordering. This is most likely not implemented on your operating system."

Common protocols Name Description icmp The Internet Control Message Protocol is used primarily by gateways and hosts to report errors in datagram communication. The \"ping\" command (present in most modern operating systems) is an example application of ICMP. udp The User Datagram Protocol is a connectionless, unreliable, protocol with fixed record lengths. Due to these aspects, UDP requires a minimum amount of protocol overhead. tcp The Transmission Control Protocol is a reliable, connection based, stream oriented, full duplex protocol. TCP guarantees that all data packets will be received in the order in which they were sent. If any packet is somehow lost during communication, TCP will automatically retransmit the packet until the destination host acknowledges that packet. For reliability and performance reasons, the TCP implementation itself decides the appropriate octet boundaries of the underlying datagram communication layer. Therefore, TCP applications must allow for the possibility of partial record transmission."
