--select () is provided in BSD to provide a blocking query to multiple I/O. It provides a method of blocking queries for multiple I/O descriptors at the same time, which makes it easy to implement multiplexing. POSIX also uses this approach in accordance with the Protocol for Unified UNIX specifications, so we can use the Select method in most operating systems.Using specialized I/O multiplexer: In "UNIX?"

said the reactor three models, then Netty is what kind of it. In fact, the Netty threading model is a variant of the reactor model, which is to remove the third variant of the thread pool, which is also the default mode for Netty NiO. Participants in the reactor mode in Netty mainly have the following components: Selector eventloopgroup/eventloop channelpipeline Selector is the Selectablechannel multiplexer provided in NiO, acting as a demultiplexer

and provides information on data structure access and the maintenance of read and write locations. All 8 basic types have corresponding buffers: Bytebuffe, Charbuffer, Shortbuffer, Intbuffer, Longbuffer, Floatbuffer, DoubleBuffer. They implemented the same interface: Buffer. (2) Channel channel We read and write the data through the channel, it's like a pipe, it's a channel. the channel is different from the flow where the channel is bidirectional and can be used for reading, writing, and simul

does a lot of work for you, by multiplexing a single connection so that you can effectively use your spare time. When a different caller accesses it at the same time, it automatically uses the pipeline to detach the access request, so the work is handled by the pipeline regardless of whether it is accessed in a blocking or asynchronous manner. So we can have 10 or 20 previous "Get A and B" scenarios (requests from different apps), and they get connected as soon as possible. Essentially, it fill

supporting new kinds of LSR (including dense wavelength split multiplexer, plus/minus multiplexer, and fiber crossover). GMPLS uses the IGP (internal Gateway Protocol) extension to support multiple connection types, including regular, non-packet and contiguous connections into the connection state database. If the nodes at either end of the connection are able to send and receive packets, GMPLS treats the

bus width, support for byte, half word and word transmission. AHB system master, slave and infrastructure are composed of three parts. The transmission on the entire AHB is issued by master and is responded by slave. And infrastructure consists of 7 parts: Arbiter, Master-to-slave multiplexer, Slave-to-master multiplexer, Decoder, Dummy Slave, Dummy Master. Since AHB supports multiple master, arbiter is re

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. Most commonly used is the BytebufferSelector (multiplexer): Responsible for pollin

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 receiving devices. The receiver with a rate of 10gbit/s has been applied, and the 100GBIT/S device has a laboratory sample. 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
