Design and implementation of a fault management service for heterogeneous networks using Tina Network Resource architecture
Master of Science in Engineering - EngineeringFaults 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
Combining SOA and BPM Technologies for Cross-System Process Automation
This paper summarizes the results of an industry case study that introduced a cross-system business process automation solution based on a combination of SOA and BPM standard technologies (i.e., BPMN, BPEL, WSDL). Besides discussing major weaknesses of the existing, custom-built, solution and comparing them against experiences with the developed prototype, the paper presents a course of action for transforming the current solution into the proposed solution. This includes a general approach, consisting of four distinct steps, as well as specific action items that are to be performed for every step. The discussion also covers language and tool support and challenges arising from the transformation

Juniper Networks supports a technical book program to publish books by Juniper Networks
engineers and subject matter experts with book publishers around the world. These
books go beyond the technical documentation to explore the nuances of network
architecture, deployment, and administration using the Junos operating system (Junos
OS) and Juniper Networks devices. In addition, the Juniper Networks Technical Library,
published in conjunction with O'Reilly Media, explores improving network security,
reliability, and availability using Junos OS configuration techniques. All the books are for
sale at technical bookstores and book outlets around the world. The current list can be
viewed at http://www.juniper.net/books .Junos OS for SRX Series Services Gateways integrates the world-class network security
and routing capabilities of Juniper Networks. Junos OS includes a wide range of
packet-based filtering, class-of-service (CoS) classifiers, and traffic-shaping features
as well as a rich, extensive set of flow-based security features including policies, screens, network address translation (NAT), and other flow-based services.
Traffic that enters and exits services gateway is processed according to features you
configure, such as packet filters, security policies, and screens. For example, the software
can determine:
• Whether the packet is allowed into the device
• Which firewall screens to apply to the packet
• The route the packet takes to reach its destination
• Which CoS to apply to the packet, if any
• Whether to apply NAT to translate the packet’s IP address
• Whether the packet requires an Application Layer Gateway (ALG
