The study on the parameters of network reliability has been one important part of the network quantitative characteristics while current research often focused on the connectivity lacking of the network applications. Whether the network applications can meet users' demands or not is one of the important examination indexes in communication networks. The reliability parameters on communication networks...
As the high redundancy of network equipments and paths, connection reliability is no longer the most important parameter for networks. According to network function, this paper advances transmission time reliability as a common parameter to describe network congestion. It is defined to be the probability that networks will transmit material, energy or information timely when used under specified operating...
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...
Computer network reliability testing is an important technology for network reliability evaluation. Focused on reliability testing for computer network applications, the testing profile building method, the sample selection method, the failure criterions setting method and the index evaluation method are researched. Finally, the testing process is explained with a testing case.
This paper presents a new model based on the event-based reliability model (EBRM) and the Markov process to study the global reliability of telecommunication networks. This approach tries to use the independent failure events to describe the dependent link failures, and then uses the Markov process to construct the different network failure states based on the independent failure events. Finally a...
This paper proposed the layered index method for network reliability analysis through the study of the current network reliability research, as well as the existing problems. This paper first analyzed the required function, the stated condition, the specified period of the network reliability definition, then discussed the calculation of the application reliability based on individual application,...
