A star-like circuit-switching network with multistage service

A star-like circuit-switching network with multistage service is considered. Likelihood ratio ordering is used to show that there exists an optimal threshold for the mean number of messages processed through the network as a function of the input traffic intensity.

Generalized Order

Due to the importance of generalized order statistics (GOS) in many branches of Statistics, a wide interest has been shown in investigating stochastic comparisons of GOS. In this article, we study the likelihood ratio ordering of $p$ -spacings of GOS, establishing some flexible and applicable results. We also settle certain unresolved related problems by providing some useful lemmas. Since we do not impose restrictions on the model parameters (as previous studies did), our findings yield new results for comparison of various useful models of ordered random variables including order statistics, sequential order statistics, $k$ -record values, Pfeifer's record values, and progressive Type-II censored order statistics with arbitrary censoring plans. Some results on preservation of logconvexity properties among spacings are provided as well.

Traditional Program

With the rapid development of communication technology, modern communication technology has been widely penetrated into modern national defense, science and technology, people's life and other fields, and has become a means to provide high-quality and seamless information communication between people and machines. With the rapid development of computer technology and the Internet, the traditional program-controlled switching technology has come to an end, and the soft-switch network based on IP technology and packet switching has gradually replaced the program-controlled switching network based on circuit switching and become the mainstream of today's communication network world. The rapid development of VOIP telephony reduces the cost of domestic and international long-distance telephony, benefiting consumers. Digital mobile communication expands channel capacity, improves service quality and promotes the rapid development of this industry. Based on the secondary development of the open source FreeSWITCH software, this paper develops a VOIP voice system based on IP technology to meet different user needs intelligently [1].
