    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (124 KB)  

    The TINA architecture is often perceived as a service layer specialized framework; however a detailed examination of the architectural context and ongoing work in the field demonstrates that it is not so, and that the TINA architecture can also be envisioned as a network management framework if care is taken about some TMN specifics. After making that point, the article proposes a conceptual architecture for interworking TMN and TINA based systems. It then describes a component architecture for a migrating OSI MIB that demonstrates concretely the feasibility of building a TMN-able agent running in a TINA based environment View full abstract»

    TINA aims to provide an architecture based on distributed computing technologies that will enable telecommunications networks to support flexible introduction and control of new advanced services. The provided services and the supporting network and computing infrastructure will be managed in an integrated fashion. Network management aspects in TINA are addressed by its Network Resource Architecture (NRA), which has so far concentrated on connection and configuration management, with accounting, fault and performance management aspects to follow. VITAL (Validation of Integrated Telecommunication Architecture for the Long term) is a European collaborative research project that aims to validate a long-term telecommunication architecture, based on TINA, through the design, realisation and trials of a large-scale system. This paper presents the VITAL work related to the realisation of the NRA in the areas of resource configuration, connection and accounting management. The problems encountered are highlighted and the architectural solutions adopted are presented, together with examples of operation that illustrate the design of the VITAL NRA system View full abstract»

  • Enhancements on TINA connection management

    Page(s): 324 - 333

    This paper describes a contribution to connection management. The contribution is motivated mainly by shortcomings in the specifications of the TINA (Telecommunications Information Networking Architecture) connection management architecture: in particular, it is considered to be too difficult to use. The TINA specifications are based on the ODP binding model. In this model, connection management is viewed as an explicit binding service, that is, a binding service that can be controlled from the service components. Starting from this binding model, we propose a way to structure TINA connection management services. As a result, we achieve important simplifications on the current specification View full abstract»

    The network management systems for IP networks should be able to manage a large-scale network because the number of network elements increases. Currently, there are many applications of the IP network management system. These applications are being used by many users and are readily available for LANs. Though it is expected that such large-scale networks will be managed using SNMP, it is difficult to make a network management system using SNMP on a single computer. An effective way to solve this problem is to construct a network management system using a distributed processing environment. We have developed a new distributed IP network management system. The system consists of several subsystems, which enables the processing load for IP network management to be reduced. In our system evaluation, the system was implemented on DCE, a client-server environment, and it was found that the overhead time of the distributed processing was small in comparison with the overall response time View full abstract»

  • Data-driven implementation of TINA kernel Transport Network

    Page(s): 184 - 192

    To realize the actual TINA-based telecommunications network, the performance of the kernel Transport Network (kTN) such as availability, reliability, throughput and load tolerance becomes more crucial than for existing computer networks. The authors have been studying and developing a super-integrated data-driven processor to be applied to the TINA kTN nodes and network interfaces in CUE (Coordinating Users' requirements and Engineering constraints) project. Since the processor is primarily designed to be a scalable VLSI component, it is easily interconnected to form a super-integrated chip and multi-chip system for achieving the performance and reliability demanded in a TINA environment. We first examine the requirements for kTN. A stream-oriented data-driven architecture is then proposed with special emphasis on effective multiprocessing capability with overload tolerance. After that, we demonstrate that autonomous load balancing among super-integrated data-driven processors without adding any runtime overhead to achieve effective and reliable multiprocessing is possible by utilizing the overload tolerance of the processor. Finally, this paper shows preliminary performance estimations of the super-integrated data-driven processor being developed to perform efficient multiprocessing in protocol handling such as TCP/IP View full abstract»

  • Managing TINA streams that use Internet transport

    Page(s): 111 - 118
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (36 KB)  

    The current TINA Network Resource Architecture provides a flexible framework for integrated management and usage of various connection-oriented transport networks. By introducing the concept of layer network binding at the layer network level, this framework can also support connectionless transport networks. Interfaces allowing the manipulation of TCP and UDP endpoints in the terminal are specified so that IP connectivity providers can control the IP network part of TINA streams and associate it with the terminal part. The combination of these interfaces with the layer network binding concept facilitates the usage of basic and advanced Internet concepts such as IP unicasting and multicasting for TINA streams. Furthermore, it allows connectivity providers to transparently use any combination of transport network technologies, including IP, inside their network to meet the network quality of service requirements for TINA streams View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (200 KB)  

    The concept of electronic brokerage is based on the use of new information technologies so as to provide a service capable of facilitating and organising the relationship between the supply and the demand in an “electronic marketplace” environment. This new service supported by the so-called “electronic brokers”, will allow service providers to publish and advertise their offers and, at the same time, will help end users to access the offered services and information in an easy and efficient way. The paper presents an architecture for this electronic brokerage service that is currently being developed within the scope of the ABS (Architecture for Information Brokerage Service) ACTS European project. This architecture is based on concepts and principles contained in the TINA-C computing and service architecture and in the OMG EC-DTF Reference Model View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (40 KB)  

    The paper describes a CORBA based framework for the control and management of multimedia streams. The concepts of streams and flows are introduced, along with the abstractions used for multimedia devices. Examples of usage for point to point and point to multipoint streams are given. The OMG specification describes two profiles for implementers of the framework, a light profile and a full profile. The differences between these profiles are described. The Simple Flow Protocol (SFP) for transporting IDL typed and untyped flows is briefly outlined. Finally, it is shown that the full profile of the OMG stream specification can be used to implement a TINA CSM interface with only minimal changes to TINA-C IDL specifications View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (52 KB)  

    The paper is an attempt to analyze the applicability of TINA in an Internet context considering the usefulness and the need of TINA solutions from a business point of view and not in its applicability “per se”. For this reason some applicability scenarios have been chosen. They describe the applicability in a general framework more than describing the technicalities. The results are that TINA should pay more attention to the developments of the Internet in terms of protocols, APIs and products so that it could be a useful “component based architecture” for building servers and services over the Internet View full abstract»

    The paper describes how TINA (Telecommunications Information Networking Architecture) concepts can be applied to the Universal Mobile Telecommunications System (UMTS) to achieve flexible connectivity control in the radio access network. It presents a general Network Resource Information Model (NRIM) for the UMTS, defined as a strict extension of the TINA model. The required enhancements to the TINA NRIM are introduced and the application of the resulting model to the UMTS is described in detail. In particular, the multi-bearer and macro-diversity features and the handover procedure are analyzed. Examples are provided to illustrate the concepts presented View full abstract»

    The paper introduces some proposals for the support of personal mobility services in the TINA environment. In particular, the reasons for maintaining terminal information inside the network and the need to support services across different provider domains by handling them through multiple user agents are presented. The effectiveness of user agent replication is analysed by comparing the signalling load generated on the network in the hypotheses of: i) accessing remote user data associated with a single user agent; and ii) transferring these data to the visited domain where the user is actually accessing the service View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (60 KB)  

    A dynamic role creation scheme from a role class hierarchy is proposed. In combination with security space representation, algebraic operation on roles creates a new, composite role. A strongly-rolled system and role mapping between federated domains is presented. By using dynamic role creation and role mapping, complex security management in a dynamic service environment with federation and composition becomes possible View full abstract»

    We present the first results of the CrySTINA project. We analyze and structure the security problem domain in the TINA-C architecture and present our approach to provide the necessary security functionality in the form of self-contained application-independent security services and security mechanisms as part of the DPE functionality. The DPE is assumed to be basically provided by CORBA products. Therefore, we introduce the CORBA security specification and investigate if and how the identified TINA security services can be implemented using the CORBA security functionality View full abstract»

    Federation in TINA CMA (Connection Management Architecture) provides the mechanisms for cooperation between different interworking network domains possibly owned by different administrators. In order to be able to offer services to their users, these administrators must cooperate. We present an implemented and validated architecture including the federation techniques necessary. We illustrate the problem based on experience from a user trial, in which different operators, and suppliers with different equipment participate View full abstract»

    The CAMOUFLAGE Project is a national German research initiative led by the Deutsche Telekom. It aims at the provision of a TINA conforming distributed processing environment based on existing legacy telecommunication systems. The envisaged target architecture is a switched ATM network deploying B-ISDN. Using an integrative approach, a mutual stimulation between the TINA technology and the B-ISDN technology is expected. The paper presents the overall design of the CAMOUFLAGE DPE, the CMA for the B-ISDN and gives a detailed description of the B-ISDN based transport network for operational interactions. A general mechanism for the introduction of different interoperability protocols (Open Communication Interface) to CORBA is proposed. The B-ISDN protocol GFP has been selected as the foundation for the implementation for such an interoperability protocol. It allows not only a fast inter-ORB communication, but can also-due to its different modes-be tailored to the actual needs (speed, quality, amount of data). Within the scope of the transport network, a connectivity management system (CyM) based on the TINA NRA has been developed for a B-ISDN environment. Due to the fact that B-ISDN does already contain parts of the functionality required by the NRA, CyM is a subset of NRA, extended by additional objects to control the protocol stacks and the hardware. Different scenarios for the introduction of CyM have been specified, requiring only simple or no extensions to the existing B-ISDN networks View full abstract»

    The paper describes the design and implementation of a gateway that maps interactions between management applications developed using RPC/IDL to agents developed using CMIP/GDMO. In order to match both technologies, several mechanisms are necessary, and we show how to combine them in a coherent module, which can have most of these components generated by automated tools. Particularly, we demonstrate its use in a study for the integration of distributed management applications, developed over the OSF/DCE distribution platform, accessing management information on OSI managed objects, through the HP OpenView management platform View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (48 KB)  

    The paper proposes an environment for operating and managing the service-type repositories advocated by TINA-C, ISO-ODP, and OMG. The environment enables users of telecommunication services and network management services to easily find the servers that provide services they want to use. It also provides a mechanism that ensures the response time of operations performed by distributed service type repositories. Moreover, service type data replication and repository failure recovery are processed automatically. A prototype implementing IE-STREM has already been developed on a CORBA compliant product and its performance is satisfactory View full abstract»

  • An extensible and modular real-time TINA DPE kernel

    Page(s): 230 - 238
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (64 KB)  

    The article describes a minimal and modular TINA-compliant DPE Kernel architecture which allows the construction and configuration of DPE instances tailored to the specific needs of their environment and which provides the necessary handles for the execution of real time applications with end-to-end QoS constraints. The proposed architecture features a flexible binding framework allowing the introduction of arbitrary forms of binding beyond the implicit binding model assumed by CORBA. In particular, the framework described here allows the explicit establishment and control of QoS constrained bindings such as multi party stream bindings between multimedia stream interfaces. The implementation of this DPE architecture within Chorus COOL-ORE is covered in detail View full abstract»

  • Service creation on a TINA platform: an experience report

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (120 KB)  

    Tomorrow's telecommunications market in an open competitive environment will increase the pressure on operators to differentiate themselves from their competitors. This will mainly be done on the service level, thus increasing the importance of a flexible service architecture allowing for fast and cost effective development of new services. Furthermore we need a technology and provider independent architecture to provide new services on top of our heterogeneous legacy networks. The problem was already known in pure narrowband networks and most operators introduced the concept of a centralised service management platform in the network, the IN (Intelligent Network). But the IN architecture was designed for simple narrowband services and proved to be strongly technology and provider dependent. Therefore a new architecture has to be introduced to create new complex services in a fast and cost effective manner. The most promising service architecture at the moment is TINA. The paper presents the experience gained during the implementation and integration of different services on a TINA platform. Special attention is given to the time needed for the delivery of the services and the hurdles encountered during the implementation View full abstract»
