Research on distributed IMS network architecture and its key techniques
Xuan Wei, R China · Digital Communication · 2009
As the core control system of the future IP-level telecommunication network,IMS becomes more and more popular,and how to improve its reliability and load capacity has become the industrial focus.Distributed computing is one of the important research achievements in recent years in computer science.Distributed system can use the unique characteristics to solve traditional centralized network system drawbacks,but at the same time,distributed system also brought problems of low routing efficiency and poor controllability.This paper proposes a distributed IMS network system based on the bicyclo chord distributed routing strategy so as to effectively solve the centralized CSCF server single point of failure and performance bottleneck problem.Meanwhile,this technique also realizes the IMS NE's homogenization,optimizes IMS routing efficiency,and enhances the system's controllability,resilience,scalability and load balancing ability.
