Full textFull migration to IPv6 brings the need to adjust datacommunication services for the new generationof IP protocols with maintained or expanded functionality. This thesis’ goals is to submitone or more solutions that meets requirements and the technical conditions that enables thecompany DGC:s to expand the service IP-VPN for IPv6. This includes address assignmenttechniques like prefix delegation and automatic address configuration in existing network infrastructure.Solutions are presented in six scenarios that have been investigated considering tests, analysis andexperienced problems. The investigation formed the criteria scalability, configuration complexity,compatibility, support by RFC:s and requirements stated by DGC that adds to the evaluationof the most suitable solution.The evaluation has resulted in a recommended scenario that is implementable according to givengoals.Techniques that may influence the choice of most suitable solution, but that is not yet available,are discussed and presented to point out what may needed to be considered in the future.

Full textThe subject concerns the management of the Information systems and Telecommunications. I propose a detailed description of various topologies of inter-connection and security. I propose a modelisation of the information processing systems, to study the behavior of the systems on models and not on the system itself. I present an innovating solution based on the concept of IP collect and Multi operator routing, using the XDSL technologies of infrastructure operators, to the router in a centralized site. I propose project guidelines and methodology intended to provide a common framework covering the control of the fundamental processes and their organizational and technical impacts on the deployment in companies

Full textDuring 2012, the global mobile traffic represented 70\% more than 2011. The arrival of the 4G technology introduced 19 times more traffic than non-4G sessions, and in 2013 the number of mobile-connected to the Internet exceeded the number of human beings on earth. This scenario introduces great pressure towards the Internet service providers (ISPs), which are called to ensure access to the network and maintain its QoS. At short/middle term, operators will relay on alternative access networks in order to maintain the same performance characteristics. Thus, the traffic of the clients might be offloaded from RANs to some other available access networks. However, the same security level is not ensured by those wireless access networks. Femtocells, WiFi or WiMAX (among other wireless technologies), must rely on some mechanism to secure the communications and avoid untrusted environments. Operators are mainly using IPsec to extend a security domain over untrusted networks. This introduces new challenges in terms of performance and connectivity for IPsec. This thesis concentrates on the study of the mechanism considering improving the IPsec protocol in terms of continuity of service. The continuity of service, also known as resilience, becomes crucial when offloading the traffic from RANs to other access networks. This is why we first concentrate our effort in defining the protocols ensuring an IP communication: IKEv2 and IPsec. Then, we present a detailed study of the parameters needed to keep a VPN session alive, and we demonstrate that it is possible to dynamically manage a VPN session between different gateways. Some of the reasons that justify the management of VPN sessions is to provide high availability, load sharing or load balancing features for IPsec connections. These mechanisms increase the continuity of service of IPsec-based communication. For example, if for some reason a failure occurs to a security gateway, the ISP should be able to overcome this situation and to provide mechanisms to ensure continuity of service to its clients. Some new mechanisms have recently been implemented to provide High Availability over IPsec. The open source VPN project, StrongSwan, implemented a mechanism called ClusterIP in order to create a cluster of IPsec gateways. We merged ClusterIP with our own developments in order to define two architectures: High Availability and Context Management over Mono-LAN and Multi-LAN environments. We called Mono-LAN those architectures where the cluster of security gateways is configured under a single IP address, whereas Multi-LAN concerns those architectures where different security gateways are configured with different IP addresses. Performance measurements throughout the thesis show that transferring a VPN session between different gateways avoids re-authentication delays and reduce the amount of CPU consumption and calculation of cryptographic material. From an ISP point of view, this could be used to avoid overloaded gateways, redistribution of the load, better network performances, improvements of the QoS, etc. The idea is to allow a peer to enjoy the continuity of a service while maintaining the same security level that it was initially proposed

Full textThe phenomena risk and crisis as challenges facing the management of communications processes in business, politics, and society provide the subject for this work, the goal of which is a theoretically-based framework laying the groundwork for operative measures in communications with respect to risk and crisis situations. Having first defined relevant terms and conditions for communication, the work analyses risk and crisis communications from the standpoint of a game and illustrates the structures created as the game runs its course. These structures are crucial elements in determining not only participants' but also observers' freedom to act and the expectations they develop. In addition to a critical discussion of available models for the management of risk and crisis communications, the work contains the results of a standardized written polling of experts in the field of corporate communications. Crucial goals of this research were to identify and quantify apparent differences in the assessment of theory and practice. Observations as to how to maintain and ensure the continuation of communication systems provide the overlying framework for risk and crisis communications, for which aspects of image preservation, together with processes, rituals, and procedures, play an important role.

Full textExperimentation in my work means performing experiments based on computer-based models, which describe system structure and behaviour abstractly. Instead of the system itself models of the system will be explored due to several reasons. Systematic experimentation using model input parameter variation assignments leads to lots of possibly long-running experiments that must be planned, documented, automated executed, monitored and evaluated. The problem is, that experimenters (who are usually not computer scientists) miss the proper means of expressions (e. g., to express variations of parameter assignments) to describe experimentation processes formally in a way, that allows their automatic execution by a computer system while preserving reproducibility, re-usability and comprehension. My approach is to identify general experimentation workflow concepts as a specialization of a scientific workflow and formalize them as a meta-model-based domain-specific language (DSL) that I call experimentation language (ExpL). experimentation language (ExpL) includes general workflow concepts like control flow and the composition of activities, and some new declarative language elements. It allows modeling of experimentation workflows on a framework-independent, conceptional level. Hence, re-using and sharing the experimentation workflow with other scientists is not limited to a particular framework anymore. ExpL is always being used in a specific experimentation domain that has certain specifics in configuration and evaluation methods. Addressing this, I propose to separate the concerns and use two other, dependent domain-specific languages (DSLs) additionally for configuration and evaluation.

Full textENGLISH ABSTRACT: The aim of the exercise is to acquire a thorough knowledge of Kromco's business requirements, to create a high level datamodel, a data entity model and to determine the priorities of the different systems which will lead to an effective management information system. To acquire the desired information and strategy within a limited period of time, use was made of questionnaires, focus groups, personal interviews, value chain analysis, critical success achievements and information in use. The desired information requirements and information systems have been evaluated against the information and systems presently available. The present management information system does not fulfil the needs of a successful management information system and therefore it has been suggested that a computer be obtained. The same information is used by different departments. To prevent duplicating transactions, use must be made of a databasis. The designing of the database does not form part of this worksheet and further investigation is necessary.
AFRIKAANSE OPSOMMING: Die doelwit van die werkstuk is om 'n deeglike begrip van Kromco se besigheidsbehoeftes te verkry deur die daarstelling van 'n hoe vlak datamodel, 'n data entiteitmodel en die prioriteitsbepaling van die verskillende stelsels wat sodoende tot 'n effektiewe bestuursinligtingstelsel sal lei. Om die verlangde inligting en strategie binne die kort tydsbestek te kry is daar gebruik gemaak van vraelyste, fokusgroepe, persoonlike onderhoude, waardeketting-ontledings, kritieke suksesbepalings en bestaande inligting in gebruik. Die verlangde inligtingsbehoeftes en -stelsels is geevalueer teenoor die inligting en -stelsels wat tans beskikbaar is. Die bestaande bestuursinligtingstelsel voldoen nie aan die vereistes van 'n suksesvolle bestuursinligtingstelsel nie en die aanbeveling is om n eie rekenaar te kry. Dieselfde inligting word deur verskillende departemente gebruik. Daarom moet daar gebruik gemaak word van n databasis om duplisering van transaksies te vermy. Die databasisontwerp vorm nie deel van hierdie werkstuk nie en verdere navorsing moet daarop gedoen word.
