Is TCP or UNIX socket faster?

Unix domain sockets are often twice as fast as a TCP socket when both peers are on the same host. The Unix domain protocols are not an actual protocol suite, but a way of performing client/server communication on a single host using the same API that is used for clients and servers on different hosts.

How fast is socket communication?

On a very fast machine you can get 1 GB/s on a single client. With multiple clients you might get 8 GB/s. If you have a 100 Mb card you can expect around 11 MB/s (bytes per second). For a 10 Gig-E ethernet you might get up to 1 GB/s however you might only get half this unles syour system is highly tuned.

Why does UNIX require a domain socket?

UNIX domain sockets enable efficient communication between processes that are running on the same z/TPF processor. UNIX domain sockets support both stream-oriented, TCP, and datagram-oriented, UDP, protocols. You cannot start a UNIX domain socket for raw socket protocols.

Are UNIX sockets bidirectional?

Sockets are bidirectional, providing a two-way flow of data between processes that may or may not have the same parent. … Pipes provide a similar functionality. However, they are unidirectional, and they can be used only between processes that have the same parent.

What is Unix socket connection?

A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system. Valid socket types in the UNIX domain are: SOCK_STREAM (compare to TCP) – for a stream-oriented socket.

What is Unix domain socket path?

UNIX domain sockets are named with UNIX paths. For example, a socket might be named /tmp/foo. UNIX domain sockets communicate only between processes on a single host. … Socket types define the communication properties visible to a user. The Internet domain sockets provide access to the TCP/IP transport protocols.

What is socket file in Linux?

A socket is a file for processes to exchange data. … A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system.

What is a Unix port?

For our purpose, a port will be defined as an integer number between 1024 and 65535. … This is because all port numbers smaller than 1024 are considered well-known — for example, telnet uses port 23, http uses 80, ftp uses 21, and so on.

What is socket networking?

Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.

What is Af_unix?

The AF_UNIX (also known as AF_LOCAL) socket family is used to communicate between processes on the same machine efficiently. Traditionally, UNIX domain sockets can be either unnamed, or bound to a filesystem pathname (marked as being of type socket).

What is Unix socket in Docker?

sock is the UNIX socket that Docker daemon is listening to. It’s the main entry point for Docker API. It also can be TCP socket but by default for security reasons Docker defaults to use UNIX socket. Docker cli client uses this socket to execute docker commands by default. You can override these settings as well.

What Unix function lets a socket receive connections?

The recv function is used to receive data over stream sockets or CONNECTED datagram sockets. If you want to receive data over UNCONNECTED datagram sockets you must use recvfrom(). You can use read() system call to read the data.

What is Unix computer?

UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.
