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

摘要

The authors propose a fail-safe architecture of a networkninformation control system (NICS) and fault handling mechanisms fornhighly available NICSs. The NICS consists of seven processors, includingnduplicated common channel signaling processors (CCPS), duplicatednservice logic processors (SLPs), a service management processor (SMP),nduplicated operations and administrations processors (OAPs), andnduplicated LANs. As NICS has a fail-safe architecture and is managednwith fault-handling mechanisms, it can process service requests from thenswitching service point (SSP) continuously and NICS can be managednsafely and efficiently
