    Design and implementation of a fault management service for heterogeneous networks using Tina Network Resource architecture
    (2006-03-22) Parshotam, Chiba Chetan
    Faults are unavoidable and cause network downtime and degradation of large and complex communication networks. The need for fault management capabilities for improving network reliability is critical to rectify these faults. Current communication networks are moving towards the distributed computing environment enabling these networks to transport heterogeneous multimedia information across end to end connections. An advanced fault management system is thus required for such communication networks. Fault Management provides information on the status of the network by locating, detecting, identifying, isolating, and correcting network problems thereby increasing network reliability. The TINA (Telecommunication Information Networking Architecture) standards define a Network Resource Architecture (NRA) that provides a framework of a transport network that is capable of transporting heterogeneous multimedia media information across heterogeneous networks. TINA also defines a Management Architecture that follows the functional area organization defined in the OSI (Open Systems Interconnection) Management Framework, namely fault, configuration, accounting, performance, and security management (FCAPS). The aim of this project is to utilise the TINA NRA and Management Architecture concepts and principles to design and implement a distributed Fault Management Service for heterogeneous networks. The design presented here utilises TINA’s fault management specifi- cations, together with UML modelling tools to developed this Fault Management Service. The design incorporates the use of CORBA and SNMP to provide a distributed management functionality capable of providing fault management support across heterogeneous networks. The generic nature of the fault management service is tested on the SATINA Trial platform which consists of both an ATM network as well as an IP MPLS network. The report concludes that the Fault Management Service is applicable to any connectionoriented network that is modeled using the TINA NRA specification and principles.
