A long time ago I read a great analogy for explaining the difference between the two. I don’t remember where I read it so unfortunately I can’t credit the author for the idea, but I’ve also added a lot of my own knowledge to the core analogy anyway. So here goes: A stream socket is … Read more
Best results you’ll get with Shared Memory solution. Named pipes are only 16% better than TCP sockets. Results are get with IPC benchmarking: System: Linux (Linux ubuntu 4.4.0 x86_64 i7-6700K 4.00GHz) Message: 128 bytes Messages count: 1000000 Pipe benchmark: Message size: 128 Message count: 1000000 Total duration: 27367.454 ms Average duration: 27.319 us Minimum duration: … Read more
The answers to these questions vary depending on whether you are using a stream socket (SOCK_STREAM) or a datagram socket (SOCK_DGRAM) – within TCP/IP, the former corresponds to TCP and the latter to UDP. How do you know how big to make the buffer passed to recv()? SOCK_STREAM: It doesn’t really matter too much. If … Read more
To make understanding better , lets find out where exactly bind and connect comes into picture, Further to positioning of two calls , as clarified by Sourav, bind() associates the socket with its local address [that’s why server side binds, so that clients can use that address to connect to server.] connect() is used to … Read more
With socket.emit you can register custom event like that: server: var io = require(‘socket.io’).listen(80); io.sockets.on(‘connection’, function (socket) { socket.emit(‘news’, { hello: ‘world’ }); socket.on(‘my other event’, function (data) { console.log(data); }); }); client: var socket = io.connect(‘http://localhost’); socket.on(‘news’, function (data) { console.log(data); socket.emit(‘my other event’, { my: ‘data’ }); }); Socket.send does the same, but … Read more
I restarted this service : Host Network Service on windows Services program. And it worked. You can run these commands in the windows terminal instead, as @admin mentioned in comment section: net stop hns net start hns
There are several possible causes. The other end has deliberately reset the connection, in a way which I will not document here. It is rare, and generally incorrect, for application software to do this, but it is not unknown for commercial software. More commonly, it is caused by writing to a connection that the other … Read more
The typical approach is to use select() to wait until data is available or until the timeout occurs. Only call recv() when data is actually available. To be safe, we also set the socket to non-blocking mode to guarantee that recv() will never block indefinitely. select() can also be used to wait on more than … Read more
This error can occur when the local network system aborts a connection, such as when WinSock closes an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket). See this MSDN article. See also Some information about ‘Software caused connection abort’.
Order of magnitude: zero. In other words, you won’t see your throughput cut in half, or anything like it, when you add TLS. Answers to the “duplicate” question focus heavily on application performance, and how that compares to SSL overhead. This question specifically excludes application processing, and seeks to compare non-SSL to SSL only. While … Read more
