other threads to handle (usually using the thread pool). AIO The AIO mode is supported from JDK7. The business logic is handled by registering the event callback function in Asynchronousserversocketchannel. When the IO operation is complete, the callback function is invoked. If you pass in Asynchronouschannelgroup, you can bind the thread pool to handle the event.

At the same time, there is a demultiplexer (sorter) to sort multiple synchronous events.ProactorBoth Proactor and reactor are design patterns in concurrent programming.

multiple status bits that can be identified by selectorBuffer (buffer):A buffer is an area of memory (an array) that is wrapped in NiO as a buffer object. Buffer provides methods to access the memory.In bio, data is stored in a stream, and in NiO, the data is stored in a buffer.In addition to the Boolean other Java seven basic types have the corresponding buffer class.

operating system are generally full-duplex, so full-duplex channel streams can better map the underlying operating system's APIs.There are two major types of channel: Selectablechannel: User network read/write FileChannel: For file operations The Serversocketchannel and socketchannel that are involved in the following code are subclasses of Selectablechannel.2.4.

is that when a connection is created, it does not need to correspond to a thread, this connection will be registered on the multiplexer, so all the connections need only one thread can be done, when the multiplexer in this thread polling, found the connection on the request to open a thread to handle, That is, a request for a threading pattern.In the process of NIO, when a request comes in, open the thread

Java NiO Core Class library Multiplexer selector is based on epoll multiplexing technology implementation Compared to select, poll system calls, Epoll has the following advantages: 1. The socket descriptor (FD) that supports one process opens is unrestricted and limited to the maximum number of file handles for the operating system.The biggest flaw in select is that there is a limit to the amount of FD opened by a single process, set by Fd_setsize, an

Optical amplifiers mainly include fiber amplifiers and semiconductor optical amplifiers (SOA), in which erbium-doped fiber amplifier (EDFA) has been widely used in practical projects, the current research hotspot is bandwidth over 80nm UWB EDFA and distributed Raman fiber amplifiers. Due to its small size, gain width and amplification, switch and other functions, S

Proactor and reactor in Aces Ace_select_reactor is the default reactor implementation that is used by all platforms except Windows and will eventually wait with the Select () system function on those systems. Ace_wfmo_reactor on Windows is the default reactor implementation. The implementation does not use the Select () multiplexer, but instead uses the WaitForMultipleObjects (). When using Ace_wfmo_reactor, some tradeoffs are needed: Ace_wfmo_reac
