PPPX(4) - Device Drivers Manual # PPPX(4) - Device Drivers Manual
NAME # pppx, pppac - PPP multiplexer device
SYNOPSIS # pseudo-device pppx
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/pipex.h>
DESCRIPTION # The pppx and pppac drivers works with the npppd(8) daemon to provide network interfaces for Point-to-Point Protocol (PPP) sessions by request from the daemon. pppx operates by allocating a network interface for each PPP session. pppac concentrates multiple PPP sessions on a single network interface.

Tcp TCP(4) - Device Drivers Manual # TCP(4) - Device Drivers Manual
NAME # tcp - Internet Transmission Control Protocol
SYNOPSIS # #include <sys/socket.h>
#include <netinet/in.h>
#include <netinet/tcp.h>
int
socket(AF_INET, SOCK_STREAM, 0);
int
socket(AF_INET6, SOCK_STREAM, 0);
DESCRIPTION # The TCP protocol provides a reliable, flow-controlled, two-way transmission of data. It is a byte-stream protocol used to support the SOCK_STREAM abstraction. TCP uses the standard Internet address format and, in addition, provides a per-host collection of “port addresses”.

UDP(4) - Device Drivers Manual # UDP(4) - Device Drivers Manual
NAME # udp - Internet User Datagram Protocol
SYNOPSIS # #include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET, SOCK_DGRAM, 0);
int
socket(AF_INET6, SOCK_DGRAM, 0);
DESCRIPTION # UDP is a simple, unreliable datagram protocol which is used to support the SOCK_DGRAM abstraction for the Internet protocol family. UDP sockets are connectionless, and are normally used with the sendto(2) and recvfrom(2) calls, though the connect(2) call may also be used to fix the destination for future packets (in which case the recv(2) or read(2) and send(2) or write(2) system calls may be used).

VETHER(4) - Device Drivers Manual # VETHER(4) - Device Drivers Manual
NAME # vether - virtual Ethernet interface
SYNOPSIS # pseudo-device vether
DESCRIPTION # The vether interface simulates a normal Ethernet interface by encapsulating standard network frames with an Ethernet header, specifically for use as a member in a bridge(4).
To use vether the administrator needs to configure an address onto the interface so that packets can be routed to it.
