demand, the transmission bandwidth can increase. The transmission bandwidth potential of optical fiber is almost unlimited compared with the access network demand. ◆ The transmission distance is far. The transmission distance can reach 70 ~ 80 km. ◆ User information isolation is good. The network topology of the Active Optical Network is either star or ring. Logically, the transmission mode of user information is point-to-point. ◆ Mature technology: SDH devices and PDH devices have been widely

-ready event occurs, the event splitter invokes the event handler registered in the first step4. The event handler performs the actual read operation first and then further processes the read-based contentA write operation is similar to a read operation, except that the first step is to register a write-ready event. Let's take a look at the process of read and write operations in Proactor mode:Read operation:1. The application initializes an asynchron

reactor mode. The reactor mode is applied to synchronous I/O scenarios. Let's take the read and write operations as an example to see the specific steps in the reactor: Read operation: 1. Application Registration and read requires the event and associated event Processor 2. Wait for the occurrence of the event. 3. When an event is required for reading, the event splitter calls the event processor registered in step 1. 4. The event processor first per

collection object and supports collection changes. The Interpreter mode encapsulates changes in specific fields and supports frequent changes in domain issues. The Observer mode encapsulates object notifications and supports communication object changes. The Visitor mode focuses on encapsulating object operation changes and supports dynamically adding new operations to the class hierarchy at runtime. Relationship Diagram between modes Example: comprehensive application of the model Let's tak

From: https://www.ibm.com/developerworks/cn/linux/l-linux-slab-allocator/ Good operating system performance depends on the ability of the operating system to effectively manage resources. In the past, heap memory manager was the actual specification, but its performance was affected by the demand for memory fragmentation and memory recovery. Now, the Linux kernel uses a method originating from Solaris, but this method has been used for a long time in the embedded system. It allocates memory a

kernel. Currently, Java does not support this Io model. After figuring out the above concepts, let's look back at the reactor mode and proactor mode. (In fact, both blocking and non-blocking can be understood as the concept of synchronization. For Asynchronization, non-blocking will not be implemented. After receiving an asynchronous notification, the user process can directly operate the data in the user State Space of the process .) First, let's take a look at the reactor mode. The reactor

to mainform, and dockwindow is also. dockwindow is a smaller unit than dockpanel. Why do I need to add a dockwindow after using dockpanel? The reason is very simple. dockwindow is used to divide dockpanel! So, so far, the architecture on your mainform should be like this. On a dockpanel, there are several dockwindows that divide the dockpanel into several pieces. by default, dockpanel uses dockwindow to create five areas: docktop, dockbottom, dockleft, dockright, and document) all regions belon

Method 1: qdirmodel is used for directory. qdirmodel is a model provided by QT for Tree display of file directories. The specific usage is as follows: # Include Int main (INT argc, char * argv []){Qapplication app (argc, argv );Qsplitter * splitter = new qsplitter;Qdirmodel * model = new qdirmodel;// Create data from the default directoryQtreeview * tree = new qtreeview (splitter );Tree-> setmodel (model )

The above is the sub menu header. Below is the sub menu After you click a top menu, all the sub menus under the top menu appear in the sub menu. Sub menu header is the name of the top menu. (Because our top menu is not selected, a sub menu header is created here to let the user know which top menu he clicked, A

, the file descriptor can be read/written, or the socket can be read/written ), the event splitter transmits the event to the previously registered event handler or callback function, and the latter performs actual read/write operations. In proactor mode, the event handler (or initiated on behalf of the event separator) directly initiates an asynchronous read/write operation (equivalent to a request), and the actual work is done by the operating syste

Two I/O multiplexing modes: Reactor and ProactorIn both modes the event multiplexer feedback to the program information is not the same:The 1.Reactor mode shows that you can read and write (send and receive) operations.The 2.Proactor mode indicates that the read-write (send a
