--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

In other words, the nohup command actually separates the child process from the session it is in.Note that the nohup command does not automatically turn the process into a "background task", so you must add a symbol.Seven, screen command and Tmux commandAnother idea is to use the terminal
