interface (API) between the data link layer and the network protocol layer. This interface is called the MUX (Multiplexer) interface in sens. MUX interface 2. On the network protocol layer, VxWorks typically uses the TCP/IP protocol (other protocols are also supported); on the data link layer, it typically uses Ethernet and also supports physical media for other data transmission, for example, the serial line access method used for long-distance con

Chen Shuo (giantchen_at_gmail)Blog.csdn.net/solstice Full muduo SeriesArticleList: http://blog.csdn.net/Solstice/category/779646.aspxI will write a series of articles about using the muduo network library to complete common TCP network programming tasks. The current plan is as follows: Simple protocols in UNP, including ECHO, daytime, time, and discard. Example in boost. ASIO, including timer2 ~ 6. Chat. Examples in Java netty include discard, ECHO, and uptime. The discard and Ec

1. dslam (DSL access Multiplexer): digital user line access multiplexing, that is, a modem combination connected to a multi-channel compound system center. It collects signals from multiple DSL connections and converts them to a high-speed line, it is used to support video, broadcast and television, fast Internet access, and other high-value applications. DSL line connections use a combination of ATM, frame relay, or IP networks. The features include

channel. The channel differs from the flow where the channel is bidirectional and can be used for read, write, and simultaneous reading and writing operations.The channels of the underlying 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:1.SelectableChannel: User network read/write2.FileChannel: For file operationThe Serversocketchannel and Socketchannel that follow the code are

complexity of programming. However, for high load and high concurrency network applications, it is necessary to develop the non blocking mode of NIO. The Netty architecture is designed and implemented in accordance with the reactor pattern, and its server-side communication sequence diagram is as follows: Figure 2-3 NiO service-side communication sequence diagram The client communication sequence diagram is as follows: Figure 2-4 NIO client communication sequence diagram Netty IO thread Nioev

Java I/O evolutionary path From JDK1.0 to Jdk1.3,java I/O class libraries are very primitive, many UNIX network programming concepts or interfaces in the I/O class library are not reflected, such as pipe, Channel, buffer and selector. When JDK1.4 was released in 2002, NiO was officially released with the JDK as a JSR-51. It adds a Java.nio package that provides a number of APIs and class libraries
