Improving sip trunking services with cloud-based SBC: Performance analysis and optimisation strategies
Abstract
In modern telecommunications networks, session initiation protocol trunking is an important technology for voice and video communication over Internet protocol networks. Cloud-based session boundary controllers play a key role in ensuring security and quality of service but there are challenges to their performance and optimisation, especially as data volume and users grow. The purpose of this study is to develop a strategy for achieving efficient and scalable session initiation protocol trunking services in cloud environments. Methods of theoretical analysis and practical experiments are used. Analysis of the performance of cloud controllers identifies important analytical conclusions about their capabilities, and the developed optimisation strategies provide practical recommendations for improving the provision of cloud trunking services. This analysis also shows that performance can vary depending on the implementation and settings. It is established that the main factors affecting performance are network latency, bandwidth, and configuration features of controllers. Based on this information, an optimisation strategy is developed, including implementing quality of service for prioritising session initiation protocol traffic, methods for automatically scaling resources, redundancy, and optimising network protocols. It is demonstrated that the use of Session Initiation Protocol-trunking and cloud-based Session Border Controller can substantially improve the quality of service in telecommunications systems, which allows optimising call routing and ensuring the security of communications. Evaluating the performance of the Session Border Controller cloud provided valuable insight into their capabilities, and the proposed optimisation strategies can become specific recommendations for improving the provision of Session Initiation Protocol trunking services in cloud environments. The results of the study can serve as valuable recommendations for telecommunications professionals who want to deploy efficient and scalable trunking solutions in cloud networks
