Depending on the platform, unix domain sockets can achieve around 50% more throughput than the TCP/IP loopback (on Linux for instance). The default behavior of redis-benchmark is to use the TCP/IP loopback.
Are UNIX sockets TCP?
Socket Use In Practice
Unix sockets are usually used as an alternative to network-based TCP connections when processes are running on the same machine. … Redis is frequently used on the same server that’s accessing it, so you’ll usually be able to use sockets.
What’s the difference between Unix socket and TCP IP socket?
A UNIX socket is an inter-process communication mechanism that allows bidirectional data exchange between processes running on the same machine. IP sockets (especially TCP/IP sockets) are a mechanism allowing communication between processes over the network.
What are UNIX sockets used for?
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.
Are UNIX sockets secure?
In short, Unix domain sockets are secure in general. You can use POSIX permissions to lock down access to the file descriptor (FD) associated with the socket, and the server side can request information such as credentials and PID of clients before they can fully connect.
Do Unix sockets have ports?
When the host is “localhost”, MySQL Unix clients use a Unix socket, AKA Unix Domain Socket, rather than a TCP/IP socket for the connection, thus the TCP port doesn’t matter.
What is TCP vs HTTP?
In Short: TCP is a transport-layer protocol, and HTTP is an application-layer protocol that runs over TCP. … Essentially, there are different protocols that let a computer talk at different distances and different layers of abstraction. At the very bottom of the network stack is the physical layer.
What is socket TCP?
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. … Every TCP connection can be uniquely identified by its two endpoints.
How do I socket in Unix?
Here are the steps:
- Call socket() to get a Unix domain socket to communicate through.
- Set up a struct sockaddr_un with the remote address (where the server is listening) and call connect() with that as an argument.
- Assuming no errors, you’re connected to the remote side! Use send() and recv() to your heart’s content!
Are sockets files?
A socket is a special file used for inter-process communication, which enables communication between two processes. In addition to sending data, processes can send file descriptors across a Unix domain socket connection using the sendmsg() and recvmsg() system calls.
