Chayapol Kamyod, Rasmus Hjorth Nielsen, Neeli Rashmi Prasad, Ramjee Prasad · 2014
The paper focuses on end-to-end resilience analysis of the IMS based network through the principal resilience parameters by using OPNET. The resilience behaviours of communication across multiple IMS domains are investigated at different communication scenarios and compared with previous state-of-the-art. Moreover, the resilience effects when adding a redundancy of the S-CSCF unit are examined. The results disclose interesting resilience behaviours for long distance communications.
