“…Certain studies have utilized Petri networks to model IMS and its related technologies, for example, the studies of Luo et al, Liu and Liu, Liu, Liu, and Chen, Mishra, Dharmaraja, and Kar, and Cheng, Junliang, and Deng . SIP noninvite transactions have been modeled in the study of Liu and Liu by using the CPNs.…”

“…In another work, the study of Liu, Liu, and Chen, the same team has used their CPN model to propose a solution to mitigate a problem in the SIP noninvite transactions, known as the losing race problem. In the study of Mishra, Dharmaraja, and Kar, a cutoff‐priority queueing scheme has been proposed to differentiate between invite and noninvite SIP traffic. This work presents two models: the first one is a node‐level continuous‐time Markov chain (CTMC) that represents a SIP server, and the second is a system‐level Petri network to model the general behavior of the proposed algorithm.…”

In the current trend in telecommunications industry towards all-internetprotocol (IP) infrastructures, IP multimedia subsystem (IMS) plays a critical role by providing a coherent data and control-plane solution for large-scale live multimedia applications in a flexible and cost-effective manner. On the other hand, such a large-scale service platform would inevitably fail without effective support for the quality-of-service (QoS) requirements perceived by its users. Among the most important factors that influence user QoS are system performance and scalability. In this paper, a performance model for IMS systems is developed using the queueing Petri nets (QPNs) as the modeling formalism.The model's parameters are tuned based on the measurements carried out using a well-known IMS implementation. The model is validated against the real system. During the model calibration, the Java garbage-collector process used in the home subscriber-server (HSS) implementation was found to be a main factor in the discrepancy between the model and the reality. In addition, the effects of other factors such as the network stack in the operating system are investigated. The validated model is employed to give insights into the scalability of every single instance of IMS implementation. The model is extended to study load balancing among multiple instances of HSS to remove the main bottleneck in the system. It provides a valuable platform for resource management of various components of the IMS ecosystem to support the intended level of QoS for the users.

“…Appling the queue theory model, a hierarchical model is presented in [14] to assess the performance of the SIP server in normal and overload states, where, Petri Net networks are used to check the network performance. In this model, two types of load management are considered to reduce retransmissions.…”

One of the most popular and widely applied protocols on multimedia networks is the Session Initiation Protocol (SIP) to create, modify, and terminate the sessions. SIP is the platform of Next Generation Networks (NGN). In this way, SIP should be able to respond to the needs of such a largely-used network. One of the major problems in SIP networks is overload. This challenge creates a sharp drop in quality of service for NGN users. In this regard, many studies have been conducted on the effectiveness of this protocol, especially under overload. A new analytical model is developed that prioritizes the SIP message processing. An analytical approach is proposed based on the Mean Value Analysis (MVA) algorithm in queue theory. Considering some appropriate assumptions customizing MVA as to implement this proposed model and to cope with the limitations of the MVA is highly essential. The output of the analytical model is compared with the standard SIP model obtained from the simulator and the results confirm that prioritizing original messages would enhance the SIP performance at different load conditions. Prioritization of original messages is advantageous, and outperforms the normal SIP. Nevertheless, prioritizing the repeated messages not only has no advantage, but also its performance is less than the normal SIP.
