TLDR
A basic teletraffic model which has applications to integrated multirate services on ATM and wireless systems, and a uniform asymptotic approximation (UAA) for the blocking probabilities, which is uniformly effective for the complete range of loadings, simple to calculate and gives accurate results even for relatively small systems.Citations

A new approach for allocating buffers and bandwidth to heterogeneous, regulated traffic in an ATM node
TL;DR: A new approach to determining the admissibility of variable bit rate (VBR) traffic in buffered digital networks is developed, and the boundary of the set of admissible traffic sources is found to be sufficiently linear that an effective bandwidth can be meaningfully assigned to each VBR source.

Effective bandwidth-based admission control for multiservice CDMA cellular networks
Jamie Evans,D. Everitt +1 more
TL;DR: In this paper, the authors developed product form traffic models for single and multiple-cell code-division multiple access (CDMA) networks with multiple classes of mobile subscribers, and the key feature of this development is the specification of a flexible call admission control procedure that details the numbers of mobiles of each class in each cell that the system operator should allow in order to maintain an acceptable QoS.

A Diffusion Approximation for a Markovian Queue with Reneging
Amy R. Ward,Peter W. Glynn +1 more
TL;DR: A single-server queue with a Poisson arrival process and exponential processing times in which each customer independently reneges after an exponentially distributed amount of time can be approximated by either a reflected Ornstein–Uhlenbeck process or a reflected affine diffusion when the arrival rate exceeds or is close to the processing rate.

Performance evaluation of a new technique for IP support in a WDM optical network: optical composite burst switching (OCBS)
TL;DR: In this article, the optical composite burst switching (OCBS) technique is proposed to implement in an all-optical backbone network to support Internet protocol (LP) traffic, where several IP packets are assembled in a single macropacket, called burst.
Journal ArticleDOI
Efficiently providing multiple grades of service with protection against overloads in shared resources
TL;DR: Analysis is made possible by a new algorithm for computing blocking probabilities based on numerical transform inversion, which achieves effective separation with sharing and can be efficiently enforced and analyzed.

Theory of Functions of a Complex Variable
TL;DR: In this paper, the Laurent series is used for expanding functions in Taylor series, and the calculus of residues is used to expand functions in Laurent series volumes II, III, and IV.

Blocking in a Shared Resource Environment
TL;DR: It is shown that, for the important and commonly implemented policy of complete sharing, a simple one-dimensional recursion can be developed which eliminates all difficulty in computing quantities of interest-regardless of both the size and dimensionality of the underlying model.

Erlang capacity of a power controlled CDMA system
A.M. Viterbi,Andrew J. Viterbi +1 more
TL;DR: This work presents an approach to the evaluation of the reverse link capacity of a code-division multiple access (CDMA) cellular voice system which employs power control and a variable rate vocoder based on voice activity.
