“…In [23], the determination of G(P − p k b l , M − b l ) (and consequently the determination of CBP via (2)) is based on the algorithms of [39,40]. These algorithms were initially proposed for the CBP calculation in circuit-switched networks [41,42]. The algorithms of [39] are based on mean-value analysis and z-transforms.…”

We consider the downlink of an orthogonal frequency division multiplexing (OFDM)-based cell that services calls from many service-classes. The call arrival process is random (Poisson) or quasi-random, i.e., calls are generated by an infinite or a finite number of sources, respectively. In order to determine congestion probabilities and resource utilization, we model the cell as a multirate loss model. Regarding the call admission, we consider the restricted accessibility, the bandwidth reservation (BR), and the complete sharing (CS) policies. In a system of restricted accessibility, a new call may be blocked even if resources do exist. In a BR system, subcarriers can be reserved in favor of calls of high subcarrier requirements. Finally, in a CS system, a new call is blocked due to resource unavailability. In all three policies, we show that there exist recursive formulas for the determination of the various performance measures. Based on simulation, the accuracy of the proposed formulas is found to be quite satisfactory.

“…Since Riordan's formulas (13) and (14) allow us to determine the variance of overflow traffic with the assumption that offered traffic is Erlang traffic, then it is necessary to convert Engset and Pascal traffic A i, j,X into equivalent Erlang traffic ( A i, j,X ) * Er that overflows from the equivalent resources with the capacity ∆V * i, j, x . To achieve that, the concept of equivalent resources (Sect.…”

“…In optical networks, the traffic overflow mechanism is one of the key mechanisms, considered as early as the dimensioning stage for these networks (e.g. in Optical Burst Switching Networks) [12], [13]. Traffic overflow is also widely used in access networks, primarily in mobile wireless networks, [14].…”

“…[56], [57] propose SR models with offered overflow traffic with a required value of the peakedness factor. In [13], [58], [59], overflow systems are considered in which PR and SR have different service parameters (service time, bitrate). In [60], to describe overflow systems, a two-dimensional convolution algorithm is used, while in [61], an overflow system is approximated by an EIG model (Erlang Ideal Grading) [62].…”

This article presents a universal and versatile model of multiservice overflow systems based on Hayward's concept. The model can be used to analyze modern telecommunications and computer networks, mobile networks in particular. The advantage of the proposed approach lies in its ability to analyze overflow systems with elastic and adaptive traffic, systems with distributed resources and systems with non-full-availability in primary and secondary resources.

“…Then, overflow traffic and the capacity of the overflow group are divided by the peakedness coefficient and as a result the parameters of the equivalent group with Erlang traffic that serves as a basis for a determination of the blocking probability in the overflow group are obtained. Overflow systems with multiservice traffic have been addressed in a great number of investigations, for example, in [52][53][54][55][56]. The basis for the model of the overflow link in the switching network adopted in this section is [54] that generalizes the model [51] into multiservice systems.…”

This paper proposes a new analytical model of a multiservice switching network with overflow links in the first stage and resource reservation for selected call classes in output directions. The proposed model assumes that both the overflow mechanism and the resource reservation mechanism can be used in a number of selected, or all, classes of calls. A particular attention is given to the way the effective availability parameter for networks with overflow links in the point-to-point selection mode is determined. The proposed model makes it possible to determine dependencies between the internal blocking probability, capacity of overflow links, and the number of reserved resources for call classes to be analysed. Simulation experiments confirm high accuracy of the proposed method and potential applications of the model in engineering issues.
