A fail-safe architecture of service control and management system for intelligent networks

The authors propose a fail-safe architecture of a network information control system (NICS) and fault handling mechanisms for highly available NICSs. The NICS consists of seven processors, including duplicated common channel signaling processors (CCPS), duplicated service logic processors (SLPs), a service management processor (SMP), duplicated operations and administrations processors (OAPs), and duplicated LANs. As NICS has a fail-safe architecture and is managed with fault-handling mechanisms, it can process service requests from the switching service point (SSP) continuously and NICS can be managed safely and efficiently.<
