International Journal of Internet Protocol Technology (IJIPT), Vol. 3, No. 4, 2008

Abstract: The delivery of highly available and robust service offerings is a critical objective for Service Providers. Despite current deployment of IMS-based architectures assumes a vertical integration, IMS-based services can be offered without having a control on the underlying IP network. This paper introduces a solution to enhance the robustness of IMS-based architectures without assuming a vertically integrated system. The paper focuses on failures experienced by core service nodes and describes an autonomic solution to allow customers access to the service during failures.
