This article describes how to send multiple-bytes (chars) out-of-band data by using Winsock. The sample applications are created in Microsoft Visual C++. Because this OOB mechanism is not directly supported at the Microsoft Windows socket level, you must implement th...
How Does TCP/IP Send Data?
For example, if you’re sending data from Host A to Host B, as shown in Figure 9-1, your bytes leave the application layer on Host A and travel through the transport and network layers on Host A; then they go down to the physical medium, across the medium, and up again through the...

After the app joins the group, it receives messages sent to the multicast group and can also send messages to the multicast group. The UI will display all data sent to the multicast group. You can also type in a message and send it to the multicast group....
Have you considered usingsocket.ioto handle the WebSocket end of things? Then it's simple, just usedgramto send data over UDP: io.sockets.on('connection', function (socket) { socket.on('sendudp', function (data) { var buf = new Buffer(data), udp = dgram.createSocket("udp4"); ...
You can tell NetworkManager to disregard an interface by using plugins. If you’re using the ifupdown plugin (for example, in Ubuntu and Debian), add the interface configuration to your /etc/network/interfaces file and then set the value of managed to false in the ifupdown section of the ...
For the sake of simplicity, and to keep this topic self-contained, we will use the built-in Simple TCP/IP Services on your computer as the server side of this communication. To create a similar client app using a UDP socket, see How to create and use a UDP socket client app for ...
If you change MaxPacketSize to a value of 1, you force the client to use TCP to send Kerberos traffic through the VPN tunnel. Because TCP is connection oriented, it is a more reliable means of transport across the VPN tunnel. Even if the packets are dropped, the server will re-request...
While trying to use nil or empty Data() as a content parameter on 'ready' UDP connection (it has no sense for TCP connection at all) func send(content: Data?, contentContext: NWConnection.ContentContext = default, isComplete: Bool = default, completion: NWConnection.SendCompletion) no pack...
