Flash/flex also supports socket-based network connections, and the server can be developed in any language such as C++,vb,c#,java. Listening to a network port can receive connections from clients that are Flash/flex developed. ActionScript 3.0 provides a way to communicate with the server side through a socket connection. This is an important feature beyond the

Socket Chapter Reading notesHighly recommended Linux/unix system programming manual, known as the God book Beyond Apue.Backlog meaning#include int listen(intint backlog)The backlog parameter limits the number of pending connections (not accept), and within that number,connect will succeed immediately .The upper limit on Linux is 128, defined inUDP is connected to the socketA UDP

Flash/flex also supports socket-based network connections. The server can be developed in any language, such as C ++, VB, C #, and Java. Listening to a network port can receive the connection from the client developed by Flash/flex.ActionScript3.0 communication with the server through socket connection is provided.

http://blog.csdn.net/eyu8874521/article/details/8847173Degrees Niang gives the description:Often also referred to as a "socket," which describes the IP address and port, is a handle to a communication chain. Hosts on the internet typically run multiple service software, while providing several services. Each service opens a socket and binds to a port, and the different ports correspond to different services

:-1 is returned, and the errno value is set. Backlog description: For a given listening set interface, the kernel needs to maintain two queues: 1. The client has sent the request to the server, and the server is waiting for the TCP three-way handshake process to be completed. 2. Queue with Connection completed However, the sum of the two queue lengths cannot exceed the backlog If the backlog argument is greater than the value in/proc/sys/NET/CORE

can apply to sockets; so_reuseaddr socket options so that ports can be reused immediately. Consider The example in Listing 3. Before binding the address, I call setsockopt with the SO_REUSEADDR option. To allow address reuse, I set the integer parameter (on) to 1 (otherwise, it can be set to 0 to prohibit address reuse). Listing3. Useso_reuseaddrsocket option avoids address usage errorsint sock, ret, on;struct sockaddr_in servaddr;/* Crea

Ruby provides two access-level network services. At a lower level, you can access the underlying operating system, which enables both client and server-oriented connections and connectionless protocols to support basic sockets. Ruby also has a library of libraries that provide a higher level of access to specific application-level network protocols, such as Ftp,http. This tutorial introduces the concept of Ruby socket

Socket (socket) is a protocol-independent network programming interface. In the OSI model, it focuses on the Session Layer and transmission layer. Socket actually represents a valid endpoint for communication between two entities. You can obtain the source IP address, source port, destination IP address, and destinatio

Socket programmingThe source of this blog post I have always thought that the network programming this piece of knowledge can also be, today suddenly has involved the client and server-side communication of this piece of knowledge of the application, found that they are not so familiar with this piece, tinker for a long time, so I want to pass this article blog record, also hope to give more

As a TCP Service Program At the same time, there may be a large number of clients connected, and we hope to remember each socket separately Who has the data to read and put it in a request queue -- these tasks are completed by one thread and another result queue. If the result contains the socket number, use a thread to specifically: Retrieve the original sender's sock
