Java Network IO Programming, from traditional bio (synchronous blocking) to NiO (synchronous non-blocking) to AIO (asynchronous non-blocking). Scenario: The client wants to send a request to the server, the server will set up a thread response for each client, the problem is, if the client has a delay and other exceptions, more network anomalies, so that the server for its established thread, has been in the waiting state, This thread takes a long ti

The users ' permissions and rights is based on their identity, clearance, and/or group membership. Access controls give organizations the ability to control, restrict, monitor, and protect resource availability, integrity , and confidentiality.Access control is a broad concept that includes several mechanisms for application in computer systems, networks, and information.

The most common input/output (I/O) model in Linux is synchronous I/O. In this model, when a request is sent, the application blocks until the request is met. This is a good solution because no central processing unit (CPU) is required when calling an application waiting for the completion of I/O requests ). However, in some cases, I/O requests may need to overlap with other processes. POSIX asynchronous I/O (AIO) application interface (API) provides t

Linux asynchronous I/O is a new enhancement provided by the Linux kernel. It is a standard feature of the 2.6 kernel, but we can also find it in the patch of the 2.4 kernel.The basic idea behind AIO is to allow a process to initiate many I/O operations without blocking or waiting for any operation to complete.The process can retrieve the results of an I/O operation later or when it receives a notification that the I/O operation is complete. 1. I/O mod

We know that the AIO model library in boost is implemented using epoll. Please refer to the following discussion! This article introduces the efficiency of almost all development models! 1:Epoll! = AIOI just said that the boost network library is implemented by epoll in Linux. The ACE contains ace_posix_aiocb_proactor and ace_dev_poll_reactor, which are implemented using AIO and epoll respectively. This is
