uverse reliability

Abstract: With the rapid development of science and technology, the software has become more and more powerful, and the complexity of the software has become higher and higher, thus greatly increasing the difficulty of software testing and reliability evaluation. In order to ensure the quality of a software system, it is necessary to conduct a special research on the software testing and reliability evaluat

Software reliability and Verification He Guowei, Reliability Engineering Technology Center, National Defense Science and Technology CommissionThis topic: Software ReliabilityCurrently, software is becoming more and more important in the system. As we all know, the hardware in the system has reliability metrics.And must be verified. However, if the software in the

On the way to work today, read an article about an architect who speaks about his refactoring system experience, and sees a noun, reliability 3 9, 4 9. What Ah, did not hear, the Internet search, the general system, like the traditional power system is also reliable 3 9, 4 9 said, can be said that this is the problem of system reliability, search several blog posts, keep a bit ~ ~ --------------------------

portability. There are only a few compilers available on the Dos,windows,macintosh platform, and open source software is less common. For a more detailed discussion of the open source development model, see Eric Raymond, "the Cathedral and the Bazaar". To put it simply, open source software: Open source Software (OSS), also known as opensource software (open sources software), is a computer software that can be freely obtained from source code, and the copyright owner of such software retains a

Reliability Analysis of questionnaires First, the concept:Reliability is the index that reflects the true degree of the measured feature according to the consistency or stability of the results obtained by the test tool. Generally speaking, the results of two or two Tests are the same, the smaller the error, the higher the reliability, which has the following characteristics: 1.

Because of carrying a variety of services on IP network, it is very important for the operators to provide reliable business for the users, and to provide a stable and reliable operation network can make the network operators improve their competitiveness greatly. The reliability of the backbone routers in IP network plays an important role in particular. According to www.lightreading.com statistics, the backbone of the network in the core router fail

The rapid development of broadband business has brought about profound changes in traditional telecom industry and it business. The integration of multiple services and multiple networks has become an irreversible trend. As the main network entity in metropolitan Area Network, the broadband metropolitan area Network will become the host platform of 3G, NGN and other new value-added services. 3G, NGN, such as real-time voice and video applications, requires metropolitan area network to provide

advantages of wireless network quality assessment test in these aspects, the test results play a leading role in the quality evaluation of mobile communication networks. The reliability of the test results of wireless network quality assessment reflects the test results, reflects the degree of the actual level of network quality, the test results with high reliability can reflect the user's feeling of net

Windows Server 2008 has Windows Reliability and Performance Monitor, enabling it technology to freely gain the tools to easily monitor and analyze system performance and reliability. (Note: In some pre-release versions of Windows Server 2008, this feature is referred to as the Windows Performance Diagnostics console). Windows Reliability and Performance Monitor i

Methods and Techniques for Improving Software Reliability 1. establish quality standards with reliability as the core In the software project planning and demand analysis phase, a quality standard with reliability as the core should be established. This quality standard includes functions, reliability, maintainabilit

The most common measure of measurement is the use of surveys. Reliability analysis is mainly to analyze the stability of the questionnaire measurement results, if the results of repeated measurements are very close, it can be considered that the reliability of the measurement is high. The concept corresponding to the reliability is the validity, and the validity

Big Google is quic to see if it can combine the advantages of both protocols, while achieving low latency and high reliability and applying them to higher-security protocols. This article is to introduce the QUIC protocol in detail. Speaking from the TCP protocol Currently, the data transmission of the Web platform is based on the TCP protocol. The TCP protocol requires three handshakes before creating the connection (Figure 1), and if you need to inc

http://blog.csdn.net/chexlong/article/details/6123087The TCP protocol is a connection-oriented protocol that provides reliable data transfer between different host processes. The TCP protocol assumes that the lower layer protocol (such as IP protocol) used by the network stack is unreliable, and its own mechanism guarantees the reliability of the data transmission. In the current network stack protocol family, in applications that require reliable dat

Purpose of software reliability testingThe main purposes of software reliability testing are:(1) Verify that software requirements are met correctly by executing software in a representative environment in use.(2) collect accurate data for Software Reliability Estimation. Software reliability estimation can generally b

Reliability has to do with the quality of measurement. In its everyday sense,Reliability is the "consistency" or "repeatability" of your measures.Before we can define reliability precisely we have to lay the groundwork. First, you haveTo learn about the foundation of reliability, the true score TheoryOf measurement. Al
