Channel Multiplexing Technology Multiplexing is the basic concept of communication technology, as shown in the following illustration, if a multiplexer is used at the transmitter, it can be combined to communicate using a shared channel. At the receiving end of the use of the distributor, the combined transmission of information sent to the corresponding end point. When communicating, the multiplexer is alw

responsibility is to handle all channel registrations on the selector of this thread multiplexer Set the Nioserversocketchannel. Netty creating Nioserversocketchannel objects with reflection through the factory class Setting TCP Parameters Create and initialize the Channelpipeline when the link is established. It is essentially a chain of responsibilities that handles network events and is responsible for managing and executing Channelhandler.

), close (close), the file event corresponding to the operation is generated, and the file event handler invokes the associated event handler before the socket to handle these events. CompositionThe four components of the file event handler, which are sockets, I/O multiplexers, file event dispatcher (dispatcher), and event handlers, respectively.Four components of a file event handlerA file event is an abstraction of a socket operation that produces a file event whenever a socket is ready t

The Iolinux kernel will treat all external devices as a single file, and read and write to a file invokes the kernel system command, putting back a filename descriptor ( File descriptor), the read-write to a socket will also have a corresponding descriptor, called socketfd java NiO core class library Multiplexer selector is based on Epoll multiplexing technology implementation NBSP;I/O multiplexing technology enables multiple client requests to be

for NIO 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 t

read/write of the new socket whenever the accept call on the main thread returns. The advantage of this model is that the program logic is concise and conforms to the human mind; The disadvantage is that the scalability is limited by the number of threads, and as more and more threads are connected, frequent thread switching can seriously slow down performance and have to deal with multi-threaded synchronization issues. Async Model: Asynchronous models generally use non-blocking I

The AHB is primarily used for connections between high-performance modules such as CPUs, DMA, and DSP, and acts as an on-chip system bus for the SOC, which includes the following features: Single clock edge operation, non-tri-state Implementation mode;Support burst transmission, support segmented transmission, support multiple host controllers, configurable 32-bit ~128-bit bus width, support byte, half-byte and word transmission. The AHB system consists of the main module, the module and the inf

changes, or release of compute resources. The solution given by the author is reactor mode.The reactor mode encapsulates the time-consuming IO resource as a handle object. The handle object is registered in the kernel of the operating system, and the handle object is processed when the object satisfies certain conditions (readable or writable). In reactor mode, the synchronous multiplexer is responsible for handling state changes to the han

overwhelmed to deny the client's request, and even the servers may become paralyzed. NIO is based on reactor, and when the socket has a stream readable or writable socket, the operating system processes the corresponding notification reference program, and then reads the stream to the buffer or writes to the operating system. In other words, this time, is not a connection will be a processing thread, but a valid request, corresponding to a thread, when the connection has no data, there is no wo

Similar products have Belllab Uwoa (ultra-widebandopticalamplifier), which has 80nm of available bandwidth to magnify up to 100 channel wavelength channels in a single fiber. It covers the C-band (1530~1656NM) and L-band (1565~1620nm). The British Imperial College (Ukimperialcollege) developed a broadband Raman amplifier. Stimulated Raman Amplification (stimulatedram

?? Reactor is a pattern proposed by Schmidt, Douglas C, which is widely used in high concurrency server implementations.The change mode uses event-driven mode, and when the event occurs, the corresponding event-handling code (Handler) is called.This pattern is the basis for high concurrency server. such as Nginx and LIGHTTPD.These two scenarios are ideal for large concurrency, but each with a very fast handling of requests.The usual web interview is this feature.structureContains 5 parts, handle
