Jitter calculation in Core IMS

The IP Multimedia Subsystem (IMS) enables the convergence of voice, data, and multimedia services. IMS is well integrated with existing voice and data networks, while adopting many of their key characteristics. SIP (Session Initiation Protocol) provides a pathway to build a single unified network, bridging the gap that previously existed between the once-separated Telecom and Internet networks. The Call Session Control Functions (CSCFs) servers are the key part of the IMS structure. They are the main components responsible for processing and routing signalling messages. For users and enterprise needs, network outages or significant degradations of the quality of service (QoS) become less and less tolerable. Our research works on improvement of the QoS in IMS networks. It is base in jitter calculation and proposal of reducing jitter for improving traffic.
