It is very hard and expensive to do reliability test for wireless mobile networks with its true form. OPNet is a simulation tool for network performance and reliability analysis, which is widely applied in industry. But a reliability simulation test design is usually absent when doing reliability evaluation on this platform. According to the traditional reliability test methods, this paper proposes...
Network reliability is very important in our modern society. The primary network reliability research focuses on connectivity reliability. Recently, network performance is receiving more and more attention, and network performance reliability concept is promoted, such as travel time reliability. But it is very hard to evaluate it. One of the reasons is high computational complexity. Although this...
This paper introduces the testing requirement for efficient reliability assessment of Avionics Full-Duplex Switched Ethernet (AFDX). Because traffic is the main stress for AFDX, the key elements of test profile are analyzed based on network's traffic configuration. The analysis suggests a new method for designing the test profile for reliability assessment of AFDX. Specifically, the flight envelopes...
Simulation and sampling are both important and widely used techniques in the research of networks. Scholars have already developed a variety of packet sampling techniques. However, few of these are focused on network reliability, especially in the simulation situation. In this paper, the necessity of using packet sampling techniques when evaluating network reliability in the simulation environment...
Existing network connection reliability parameters can't measure the connection situation of only some terminals in a specified terminal-set. To solve this problem, a new network connection reliability parameter, k/N-terminal reliability, is put forward. It is defined as the probability that at least k terminals of a specified terminal-set N in the network G(V, E, Phi) will connect for a given period...
As the most attractive realization of component-based software, composite Web service asks a heavy demand for reliability prediction in the early stage for service discovery and service composition. Although it is believed that input should be one of the most important aspects affecting the reliability of a component-based system, research of both giving more details on an operational profile and...
