Socket buffer size

Jan 15, 2015

Java Socket setSendBufferSize method The setSendBufferSize () method of Java Socket class sets the SO_SNDBUF option to the given value for this socket. The size value should be greater than 0. socket.recv_into (buffer [, nbytes [, flags]]) ¶ Receive up to nbytes bytes from the socket, storing the data into a buffer rather than creating a new bytestring. If nbytes is not specified (or 0), receive up to the size available in the given buffer. Returns the number of bytes received. #include ssize_t recv(int socket, void *buffer, size_t length, int flags); Description. The recv() function shall receive a message from a connection-mode or connectionless-mode socket. It is normally used with connected sockets because it does not permit the application to retrieve the source address of received data. In these cases, BeginReceiveFrom will read the first enqueued datagram received into the local network buffer. If the datagram you receive is larger than the size of buffer, the BeginReceiveFrom method will fill buffer with as much of the message as is possible, and throw a SocketException. If you are using an unreliable protocol, the excess Socket Conversion Table When you're working on a vehicle, having the right sockets is not only important to the job, but it’s also vital to the bolts you’re fastening and unfastening. Using SAE sockets on a metric bolt can cause stripping or break the fastener. That’s ~43KB for an optimal socket buffer size to maintain a full pipe for the given connection. Given the standard of 8 KB in many systems, the default would be suboptimal for this interface and round-trip time. Configuring the Socket Buffer Sizes. After the optimal socket buffer sizes are known, it’s relatively easy to configure the import socket TCP_IP = '127.0.0.1' TCP_PORT = 62 BUFFER_SIZE = 20 # Normally 1024, but we want fast response s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((TCP_IP, TCP_PORT)) s.listen(1) conn, addr = s.accept() print 'Connection address:', addr while 1: data = conn.recv(BUFFER_SIZE) if not data: break print "received data:", data

Tuning TCP/IP buffer sizes

This example shows how to set the input buffer size for a serial port object. The InputBufferSize property specifies the total number of bytes that can be stored in the software input buffer during a read operation. By default, InputBufferSize is 512 bytes. There could be a case when you would want to increase it to higher than the default size.

The size of the socket receive buffer. The value of this socket option is an Integer that is the size of the socket receive buffer in bytes. The socket receive buffer is an input buffer used by the networking implementation. It may need to be increased for high-volume connections or decreased to limit the possible backlog of incoming data. What values may Linux use for the default unix socket Interestingly, if you set a non-default socket buffer size, Linux doubles it to provide for the overheads. This means that if you send smaller packets (e.g. less than the 576 bytes above), you won't be able to fit as many bytes of user data in the buffer, as you had specified for its size.
