Cet article présente la modélisation, l'analyse et la simulation des performances du système de signalisation SIP-T (Session Initiation Protocol for Telephones) dans un réseau de téléphonie par paquets de classe opérateur pour NGN (Next Generation Networks). Jusqu'à récemment, l'un des plus grands défis de la migration du PSTN (réseau téléphonique public commuté) existant vers le NGN était de construire un réseau de téléphonie par paquets de classe opérateur qui préserve l'ubiquité, la qualité et la fiabilité des services PSTN tout en permettant la plus grande flexibilité d'utilisation. de la nouvelle technologie de téléphonie par paquets. Le système de signalisation SIP-T défini dans le projet de l'IETF (Internet Engineering Task Force) est un mécanisme qui utilise SIP (Session Initiation Protocol) pour faciliter l'interconnexion du PSTN avec le réseau de téléphonie par paquets de classe opérateur. Basé sur l'IETF, le système de signalisation SIP-T promet non seulement l'évolutivité, la flexibilité et l'interopérabilité avec le PSTN, mais fournit également la fonction de contrôle des appels du MGC (Media Gateway Controller) pour configurer, supprimer et gérer les appels VoIP (Voice over IP). dans un réseau de téléphonie par paquets de classe opérateur. Dans cet article, nous dérivons la taille du tampon, la moyenne du délai de mise en file d'attente et la variance du délai de mise en file d'attente du système de signalisation SIP-T qui sont les principaux paramètres d'évaluation des performances pour améliorer la QoS (qualité de service) et les performances du système du MGC dans le transporteur. réseau de téléphonie par paquets de classe axé sur le contournement payant ou le contournement tandem du PSTN. Tout d’abord, nous supposons un modèle mathématique de la file d’attente M/G/1 avec attribution de priorité non préemptive pour représenter le système de signalisation SIP-T. Deuxièmement, nous dérivons respectivement les formules de taille de tampon, de délai de mise en file d'attente et de variation du délai pour la file d'attente prioritaire non préemptive. En outre, quelques exemples numériques de taille de tampon, de délai de file d'attente et de variation de délai sont également présentés. Enfin, les estimations théoriques s’avèrent en excellente cohérence avec les résultats de simulation.

Abstract: This paper presents the performance modeling, analysis, and simulation of SIP-T (Session Initiation Protocol for Telephones) signaling system in carrier class packet telephony network for NGN (Next Generation Networks). Until recently, fone of the greatest challenges in the migration from existing PSTN (Public Switched Telephone Network) toward NGN is to build a carrier class packet telephony network that preserves the ubiquity, quality, and reliability of PSTN services while allowing the greatest flexibility for use of new packet telephony technology. The SIP-T signaling system defined in IETF (Internet Engineering Task Force) draft is a mechanism that uses SIP (Session Initiation Protocol) to facilitate the interconnection of PSTN with carrier class packet telephony network. Based on IETF, the SIP-T signaling system not only promises scalability, flexibility, and interoperability with PSTN but also provides call control function of MGC (Media Gateway Controller) to set up, tear down, and manage VoIP (Voice over IP) calls in carrier class packet telephony network. In this paper, we derive the buffer size, the mean of queueing delay, and the variance of queueing delay of SIP-T signaling system that are the major performance evaluation parameters for improving QoS (Quality of Service) and system performance of MGC in carrier class packet telephony network focused on toll by-pass or tandem by-pass of PSTN. First, we assume a mathematical model of the M/G/1 queue with non-preemptive priority assignment to represent SIP-T signaling system. Second, we derive the formulas of buffer size, queueing delay, and delay variation for the non-preemptive priority queue by queueing theory respectively. Besides, some numerical examples of buffer size, queueing delay, and delay variation are presented as well. Finally, the theoretical estimates are shown to be in excellent consistence with simulation results.
