    Trabalho final de mestrado para obtenção do grau de Mestre em Engenharia de Electrónica e TelecomunicaçõesMultiprotocol Label Switching (MPLS) is the principal technology used in Service Provider. Networks as this mechanism forwarding packet quickly. MPLS is a new way to increase the speed, capability and service supplying abilities for optimization of transmission resources. Service Provider networks use this technology to connect different remote sites. MPLS technology provides lower network delay, effective forwarding mechanism, ascendable and predictable performance of the services which makes it more appropriate for carry out real-time applications such as Voice and video. MPLS can be used to transport any type of data whether it is layer 2 data such as frame relay, Ethernet, ATM data etc. or layer 3 data such as IPV4, IPV6.Multiprotocol Label Switching (MPLS) é a principal tecnologia usada no Service Provider.

A tecnologia MPLS oferece menor atraso de rede, mecanismo de encaminhamento eficaz, desempenho e serviços previsíveis o que o tornam mais apropriado para executar aplicativos em tempo real, como voz e vídeo. O MPLS pode ser usado para transportar qualquer tipo de dados, seja dados de camada 2, como frame relay, Ethernet, dados ATM, etc., ou dados da camada 3, como IPV4, IPV6.N/

    Quality of service control in IP networks using Fuzzy Logic for policy condition evaluation

    This paper presents the architecture of a policy- based network management system designed specifically for Quality of Service management, where high level business policies are modeled as ECA (Event-Condition-Action) rules. Specifically, the system is mainly based on the policy architecture being proposed by the IETF (Internet Engineering Task Force), DMTF (Distributed Management Task Force), and TMF (TeleManagement Forum) standardization bodies. This work proposes a novel approach for policy condition evaluation using fuzzy logic. The fuzzy controller has the ability to examine policy conditions differently from default condition analyzers that employ simple conditions formed by a set of (IFs, ANDs and ORs), allowing the consideration and correlation of several input variables before taking decisions for the execution of policy actions. The system have been implemented and evaluated over a test bed network formed by Cisco® routers

    Suomalainen operatiivisten tukijärjestelmien toimittaja tarjoaa ratkaisuja palvelujen aktivointiin, verkkoresurssien hallintaan ja laskutustietojen keruuseen. Nämä ratkaisut ovat pääosin käytössä langattomissa verkoissa. Tässä tutkimuksessa arvioidaan kyseisten ratkaisujen soveltuvuutta palvelutoimitusprosessien automatisointiin tulevaisuuden verkkoympäristöissä. Tarkastelun kohteena ovat runko- ja pääsyverkkojen kiinteät teknologiat, joiden suosio saavuttaa huippunsa seuraavan 5-10 vuoden aikana. Näissä verkoissa palvelujen, kuten yritys-VPN:n tai kuluttajan laajakaistan, aktivointi vaatii monimutkaisen toimitusprosessin, jonka tueksi tarvitaan ensiluokkaista tukijärjestelmää. Teknologiakatsauksen jälkeen tutkimuksessa verrataan viitteellistä tuoteportfoliota saatavilla oleviin operatiivisten tukijärjestelmien arkkitehtuurisiin viitekehyksiin, ja analysoidaan sen soveltuvuus tulevaisuuden verkkoympäristöjen palvelutoimitusprosessin automatisointiin. Myös palvelutoimitusprosessien automatisointiin soveltuvien tukijärjestelmien markkinatilanne arvioidaan, ja tämän perusteella tutkitaan optimaalisinta sovellusstrategiaa. Lopulta voidaan päätellä, että tuoteportfoliolle parhaiten soveltuvin sovellusalue on kuluttajan laajakaistan, ja siihen liittyvien kehittyneempien IP-palveluiden palvelutoimitusprosessien automatisointi.A Finnish Operation Support Systems (OSS) vendor provides solutions for service activation, network inventory and event mediation. These solutions have mostly been deployed in mobile environments. In this thesis it will be studied how feasible it is to use similar solutions for service fulfilment in Next Generation Networks (NGN). NGN is a broad term that describes some key architectural evolutions in telecommunication core and access networks that will be deployed over the next 5 to 10 years. In these networks service, e.g. Triple Play or Virtual Private Network (VPN), activations require an extensive service fulfilment process that must be supported by first-class OSS. After introducing the NGN technologies, the research compares a reference product portfolio to available service fulfilment frameworks and evaluates the applicability. The study analyses the current state of service fulfilment OSS markets and evaluates various solution strategies. Eventually it will be concluded that the most interesting and adequate solution scenario is residential broadband, including value-added IP services

    VPN- Virtual Private Network

    In my thesis there is about Companies which I`m working, Bechtel- Enka GP uses VPN, Cloud Computing, and Data which are used Qos and Security. The Virtual Private Network which uses Bechtel-Enka is between a Venture Joint in Kosovo not between their selves. Because the station of servers and network is in Camp Zhur all other links are used by via Kukes VPN, Prishtina Office VPN to Camp Zhur and via Suhareke to Camp Zhur. There is in use just a Server for all these relationship. Outlook is used by all workers which share data for whole company. Phones also are included by them utilizing servers which are used for different works, one of them is using for sharing data for whole company using outlook and the other one for phones which are used intern and roaming calls. Similarly, open source software enables IT departments of a Project to quickly build and deploy applications, but at the cost of control and governance. Finally, virtual machine attacks and Web service vulnerabilities existed long before cloud computing became fashionable. Indeed, this very overlap is reason for optimism; many of these “cloud problems” have long been studied and the foundations for solutions exist. Security in today’s environments is established using strong authentication, authorization, and accounting procedures, establishing security of data at rest and in transit, locking down networks, and hardening operating systems, middleware, and application software. Surely, a general scenario has been defined. The project has also a remote office in Zhur camp so an employee has the related access to the corporate intranet. Depending on the Project requirement, the IS&T Engineers within contact with Management team have to decide the best technology is and have to be used by employees staff
