Accurate modeling of queueing dynamics is important in the design and analysis of Internet congestion control. However, as demonstrated in this paper, existing window-based queueing models [26,30] are often not capable of precisely capturing the transient behavior (i.e., self-clocking and burstiness) of TCP-like protocols and their resulting analysis may be inaccurate in practice. As one exampl...

In related research on queuing systems, in order to determine the system state, there is a widespread practice to assume that the system is stable and that distributions of the customer arrival ratio and service ratio are known information. In this study, the queuing system is looked at as a black box without any assumptions on the distribution of the arrival and service ratios and only keeping...

In this paper, the analysis of models queuing systems in relation to transport systems, associated with finding optimal proportions between quantitative values intensities service flows and trends various factors

In this paper, we proposed a new multistage virtual shared memory model for cluster based parallel systems. This model can be expanded in hierarchical manner and covered many of the previous clusters of parallel system designs. Queuing theory and Jackson queuing networks are applied for constructing an analytical model. This model gives a closed-form solution for the system performance metrics,...

In this paper, we studied single-server models of queuing-inventory systems (QIS) with catastrophes in the warehouse part and negative customers (n-customers) service facility. Consumer (c-customers) that arrived to buy inventory can be queued an infinite buffer. Under catastrophes, all system is destroyed but (on server or buffer) are still waiting for replenishment stocks. Upon arrival n-cust...
