Ability to provide network redundancy
Network throughput cannot be increased.
This is the recommended way to do this when network throughput is not a bottleneck 650) this.width=650; "title=" image "style=" Background-image:none; "border=" 0 "alt=" image "src=" http://s3.51cto.com/ Wyfs02/m00/9b/24/wkiol1le2owhmzuhaaaegox0suk461.png "" 368 "height=" 171 "/> For example, 2 links constitute a single mode po
Simple comparison of three factory models and three factory models
For a long time, I wanted to thoroughly understand the design pattern, suffer from laziness, and I have been thinking about it all the time. Recently I have arranged some time, as if I had a lot of time out of thin air. Now I am working on something in the design pattern. The learning of the des
Web server, FTP server and other network applications have "one answer" communication logic, so the above using the Libev library "one answer" model for the construction of similar server programs have a reference value; Also, for applications that require remote monitoring or remote control, The above model also provides a feasible implementation scheme.SummarizeThis article focuses on how to build a server program that provides a "one-answer", which has discussed the model implemented with th
construction of similar server programs have a reference value; Also, for applications that require remote monitoring or remote control, The above model also provides a feasible implementation scheme.SummarizeThis article focuses on how to build a server program that provides a "one-answer", which has discussed the model implemented with the blocking socket interface, using a multithreaded model, and using the event-driven server model of the Select () interface until the server model using the
Comparison of software development models
The software development model is the framework of the whole work and task of the system development, test, operation and maintenance across the entire software life cycle, and he gives the relationship between all stages of software development.

. In addition, I/O functions of multiple read operations and write operations can be detected at the same time. I/O operation functions can be called only when data is readable or writable.
E. Signal-driven I/O modelFirst, we allow the set of interfaces for signal-driven I/O, and install a signal processing function, the process continues to run without blocking. When the data is ready, the process receives a sigio signal and can call the I/O operation function in the signal processing functio
classes, make people uncomfortable ... And it's cumbersome to publish and call.Try simplejaxwsserviceexporter, you can export a endpoint simply by configuring it.But he also has a point to note, citing the Javadoc of the class:
Note that this exporter would only work if the JAX-WS runtime actually supports publishing with an address argument, i.e. I f the Jax-WS runtime ships an internal HTTP server. The the case with the Jax-WS runtime that's inclued in Sun's JDK 1.6 but not with the
In the network programming often uses the thread pool and the connection pool, today the common thread pool's basic application scenario and the model makes a simple contrast analysis.1. Business process comparison A, Non-threading pool business Flow model: Identifies the basic thread model of a non-thread pool, the number of front-end 1 connections then the front-end client 2 and the front-end server-side 3 need to establish a one-to-one thread to

Event drivers are familiar to a large number of programmers. The most interesting thing is the application in graphic interface programming. In fact, event drivers are also widely used in network programming, and large-scale
Graphic Analysis and Comparison of five Io models of UNIX
There are five I/O models in UNIX
I/O multiplexing (select and poll)
Signal-driven I/O (sigio)
Asynchronous I/O (posix.1 AIO _ series functions)
B. Block I/O modelsAn application calls an I/O function, l
When I read "big talk Design Patterns", I said it reflected the joy of the programmer. At that time, I didn't quite believe that I would not reflect it after all. I don't even know when to use reflection. I can only check some information and know that there are some reflection.
I have been working on a talent management system over the past few days. One of the reasons is the operation log, especially when I modify each field. Well, there were two decisions at that time. 1. Create a structure t
Comparison of various modelsEach Software Development Organization should select a software development model suitable for the Organization and change with the specific product features being developed to reduce the disadvantages of the selected model and make full use of its advantages, the following table lists the advantages and disadvantages of several common models.

I think we are all familiar with the factory model, but to distinguish simple factories, abstract factories, the factory model may not be so easy. So I looked at a lot of information and design patterns
In high-performance computing (HPC), thread models include OpenMP, TBB, and local threads.
The followingArticleIs the content related to the thread model in HPC:
(1) choose intel thread building module? OpenMP? Or a local thread?
(2) high-performance computing thread model: pthreads or OpenMP?

Comparison of Linux threading models: Linuxthreads and NPTLGNU_LIBPTHREAD_VERSION macroMost modern Linux distributions have linuxthreads and NPTL preinstalled, so they provide a mechanism to switch between the two. To see which line libraries is being used on your system, run the following command:$ getconf GNU_LIBPTHREAD_VERSIONThis produces output similar to the following:NPTL 0.34Or:linuxthreads-0.10The
