What is UdpClient?

The UdpClient class provides simple methods for sending and receiving connectionless UDP datagrams in blocking synchronous mode. Because UDP is a connectionless transport protocol, you do not need to establish a remote host connection prior to sending and receiving data.

Is UdpClient thread safe?

I know that UdpClient isn’t thread-safe (according to MSDN documentation), what is the best way to support multithreaded without using locking mechanism? On each send create new instance of the UdpClient? (just use some local UdpClient var). performance? Use ThreadLocal for the UdpClient?

How do I set up UDP client?

UDP Server :

  1. Create a UDP socket.
  2. Bind the socket to the server address.
  3. Wait until the datagram packet arrives from the client.
  4. Process the datagram packet and send a reply to the client.
  5. Go back to Step 3.

What is Af_inet?

AF_INET is an address family that is used to designate the type of addresses that your socket can communicate with (in this case, Internet Protocol v4 addresses). When you create a socket, you have to specify its address family, and then you can only use addresses of that type with the socket.

What is IP address any?

Provides an IP address that indicates that the server must listen for client activity on all network interfaces.

How do I run a UDP program?

Implementation of UDP Client Server Program

  1. Create a UDP socket.
  2. Bind the socket with the proper IP (Internet Protocol) address and the port number.
  3. Wait for the datagram packet from the client.
  4. Process the datagram and send the reply.
  5. Finish.

What is a Sockaddr?

sockaddr is used as the base of a set of address structures that act like a discriminated union, see the Beej guide to networking. You generally look at the sa_family and then cast to the appropriate address family’s specific address structure.

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).

How do I connect to UDP socket?

Calling sendto for two datagrams on an unconnected UDP socket then involves the following six steps by the kernel:

  1. Connect the socket.
  2. Output the first datagram.
  3. Unconnect the socket.
  4. Connect the socket.
  5. Output the second datagram.
  6. Unconnect the socket.

How does UDP protocol work?

The User Datagram Protocol (UDP) is a lightweight data transport protocol that works on top of IP. UDP provides a mechanism to detect corrupt data in packets, but it does not attempt to solve other problems that arise with packets, such as lost or out of order packets.
