Abstract:
The Next Generation Network (NGN) is a telecommunications system that converges all services and information into packets for transfer, accommodating technical advancements high-speed and diversified services through its multilayer architecture. The NGN enables users to consistently and efficiently obtain services, and 5G cellular communication is a viable technology to meet the demand for high data rates in the future, particularly with its mmwave capacity. However, one of the major problems that the new generation faces is non-line-of-sight status, which results from higher frequencies' extreme vulnerability to interference from obstructions and misalignment. This special property makes it more difficult for the widely used Transmission Control Protocol (TCP) to achieve good throughput and low latency across an equitable network. TCP must modify the congestion window size in accordance with the state of the network, but it is unable to effectively adapt to its congestion window, resulting in degradation of the protocol's throughput. This research presents an in-depth analysis of trustworthy communications in 5G networks, examining how TCP affects 5G mmWave networks, the mechanisms and parameters of TCP that portrays the behavior of 5G networks, and a study of the existing problems, and ideas to be fixed. It also suggests a viable study of different methods to enhance reliable communications in 5G networks.

Abstract:
The telecommunication numbering system in Indonesia currently complies to the International TelecommunicationUnion (ITU) standard, that is ITU-T E.164. In accordance to both technology development and the growing of network users, ITU has also been designing future infrastructure network concept, namely Next Generation Network Infrastructure (NGNI). In its technical paper, ITU discusses future generation’s specification as well as current network migration scenarios towards Next Gereration Network (NGN) in developing countries and its impact on regulations, business processes, and the numbering system. The scenario described in the concept is yet universal and the implementation would be highly depending on the conditions of ones country. This paper proposes the roadmap of numbering system from the current state into NGN numbering for the case of Indonesia. The method used in this paper are benchmarking with several countries that have started with the transformation process, forecasting with regression method based on the existing trends and descriptive analysis. This paper has proposed the stages of numbering roadmap towards NGN numbering system, the achievement parameters, and the indicators that are suitable for Indonesia.

Abstract:
This paper provides the state of art and hints on how to lay the foundations of an adaptive QoS approach in Next Generation Networks (NGN). The key idea is to provide a model, which would offer one application version or another, depending on the Quality of Service (QoS) negotiated at the session establishment in a NGN. The stake of this research is a better-balanced usage of the network, for maximizing the service offered to the user given his or her network capacities. It encompasses the model for such an implementation in a NGN as IP Multimedia Subsystem (IMS).

Abstract:
Modern subscribers of infocommunication services require a wide class of different services and applications, implying a wide variety of protocols, technologies and transmission rates. Networks are overloaded in the prevailing situation in the market of infocommunication services: they are overflowing with numerous customer interfaces, network layers and are controlled by too many control systems. High operating costs are pushing operators to look for solutions that simplify the operation, while maintaining the possibility of creating new services and ensuring the stability of existing sources of income from the provision of communication services. The NGN concept is the concept of building next-generation communication networks (Next-generation network), providing an unlimited set of services with flexible settings for their management, personalization, creation of new services through the unification of network solutions. Multiservice network is a communication network that is built in accordance with the NGN concept and provides an unlimited set of infocommunication services (VoIP, Internet, VPN, IPTV, VoD, etc.). An NGN is a packet-switched network suitable for the provision of telecommunication services and for the use of multiple broadband transport technologies with QoS enabled, in which the service-related functions are independent of the applied transport technologies. The main feature of NGN networks is the differentiation between services and transport technologies. This allows to view the network as a logically divided entity. Each layer of the network can evolve independently without affecting other layers. Inter-layer communication is based on open interfaces. The logical separation principle allows the provision of both existing and innovative services access technologies regardless of the used transport. The basic principle of the NGN concept is to separate from each other transfer and switch functions, call control functions and service control functions.

In NGN, the open interfaces and the IP protocol make the hazard of security aspect increased accordingly. Thereby, it is a very important premise for NGN network operation to afford a good secure media stream communication. In this paper, we will present a secure media stream communication for NGN. Then we will discuss the three parts of the media stream secure communication——media stream source authentication, secret key negotiation and distribution; media stream encryption/decryption in detail. It can effectively realize media stream end-to-end secure communication. Meanwhile, it also makes use of the expanding of former protocol during the secret key negotiation process.

The emergence and evolution of Next Generation Networks (NGN) have raised several challenges mainly in terms of heterogeneity, mobility and security. In fact, the user is able, in such environment, to have access to many networks, via multiple devices, with a vast choice of services offered by different providers. Furthermore, end-users claim to be constantly connected anywhere, anytime and anyhow. Besides, they want to have a secure access to their services through a dynamic, seamless and continuous session according to their preferences and the desired QoS. In this context, security represents an important concern. In fact, this user-centric session should obviously be secured. However, many challenges arise. In such environment, system boundaries, which were well delimited, become increasingly open. Indeed, there are multiple services which are unknown in advance and multiple communications between services and with users. Besides, heterogeneity of involved resources (terminals, networks and services) in the user session increases the complexity of security tasks. In addition, the different types of mobility (user, terminal, network and service mobility) affect the user-centric session that should be unique, secure and seamless and ensure continuity of services

Abstract:
The concept of Next Generation Network NGN (Next Generation Network), which uses TCP / IP technology as a basis for building multiservice networks, gives the operator great opportunities to organize a virtually unlimited number of services. But at the same time it sets new challenges in terms of creating and implementing new methods of traffic service. The struggle for resources affects the quality of service for all types of traffic, including IPTV traffic. The modern model of differentiated service provides for the division of traffic into classes with giving them different priorities in service. The problem of establishing priorities for different types of traffic was solved by the method of reducing individual quality indicators to a generalized value function of the additive type using weights.

Abstract:
La capacité à assurer la mobilité sans couture avec une E2E QoS sera capitale pour la réussite du NGN (Next Generation Network). Pour ce faire, les verrous à lever que nous avons relevés dans cette thèse se positionnent à l’interconnexion de trois domaines, à savoir : les mobilités, l’hétérogénéité et les préférences utilisateur. Notre première proposition d’ordres organisationnel et fonctionnel, pour laquelle nous préconisons la convergence des trois plans (user, contrôle et gestion) et les fonctionnalités associées. Ainsi nous obtenons une QoS dynamique pour satisfaire l’approche orientée «User-Centric ». Afin de mettre en œuvre la E2E QoS incluant la personnalisation dans la session «User-Centric», nous avons proposé une «Signalisation dynamique d’E2E QoS», qui est d’ordre protocolaire, sur le niveau de service afin de parvenir à la fourniture des services demandés par l’user et de se conformer au SLA. Pour couvrir tout impact de mobilité, nous avons ensuite proposé un « E2E Session Binding cross layer » au sein de notre architecture à quatre niveaux de visibilité (Equipement, Réseau, Service et User). Par le binding nous assurons la cohérence des informations entre les quatre niveaux de visibilité. Au-delà du binding, notre contribution sur la dimension informationnelle a porté sur les profils impliqués dans chaque étape du cycle de vie du service incluant les critères de QoS, les quels fournissent une image générique des composants du système de l'utilisateur et de toutes les ressources ambiantes. Finalement, nous montrons la faisabilité de nos contributions à travers des expérimentations sur notre plate-forme
The ability to provide seamless mobility with E2E QoS will be critical to the success of NGN (Next Generation Network). For this aim, the research of this thesis is positioned at the interconnection of three areas: mobility, heterogeneity and user preferences. Our first proposal is in organizational and functional levels, for which we advocate the convergence of three levels in the network (user, control and management) and associated functionality. Thus we get a dynamic QoS-oriented approach in order to satisfy the "User-Centric". For implementing the E2E QoS including personalization in the "User-Centric” session, we proposed a “dynamic E2E QoS Signalling” in the service layer. The proposal provides an end-to-end provisioning among the service components with information on four levels (equipment, access network, core network and service). Considering any impact of mobility, we proposed also a “cross layer E2E Session Binding” in our architecture for ensuring information consistency among the four levels of visibility. Meanwhile, our contribution in the informational dimension focused on the profiles involved in each stage of service life cycle including the QoS criteria, which provide a generic image of the components of the user's system and all environmental resources. Finally, we presented the feasibility of our proposals through the experiments on our platform

Abstract:
Aujourd'hui, le marché des services est devenu de plus en plus concurrentiel. Les exigences des clients pour des offres de service en adéquation avec leurs usages et leurs préférences conduisent les fournisseurs à proposer de nouveaux services qui répondent à ce nouveau besoin pour se démarquer des concurrents et attirer de nouveaux clients. Avec la convergence des réseaux et celle des services de nouvelle génération (NGN/NGS), de nouveaux services sont apparus. Les utilisateurs sont nomades et veulent utiliser leurs services de différentes manières n'importe où, n'importe quand et par n'importe quel type de terminal, et cela avec une continuité de service et une qualité de service de bout en bout. Ainsi, fournir des services personnalisés aux clients dans un environnement hétérogène et mobile devient un challenge pour les opérateurs et les fournisseurs de service pour améliorer le retour sur investissement (ROI) et le délai de mise sur le marché (TTM). Nos réflexions à propos de la fourniture des services personnalisés selon les besoins fonctionnels et non-fonctionnels (QoS) des usagers, nous ont conduits à identifier les besoins du nouveau contexte NGN/NGS défini par l'intersection de ces trois éléments "user-centric, mobilité et QoS". Comment piloter dynamiquement la QoS de bout en bout pour une session unique "user-centric"? Comment assurer le " service Delivery" dans un contexte de mobilité et d'ubiquité? Ces nouveaux besoins, nous ont motivé à proposer des solutions à travers trois contributions principales qui prennent en considération la vision utilisateur et opérateur. Notre première contribution porte sur le modèle organisationnel. Nous proposons une nouvelle organisation avec un maximum de flexibilité, d'adaptabilité et d'autogestion, qui permet de piloter la QoS à chaque niveau de l'architecture (équipement, réseau et service). Dans cette organisation nous avons défini des acteurs et le rôle que joue chacun d'eux par rapport à la prise de décision au cours de la session de l'utilisateur, et cela pour maintenir la QoS de bout en bout dans un environnement qui est totalement hétérogène et mobile.Notre deuxième contribution traite du composant de service autonomique. Avec la complexité de la personnalisation des services dans un contexte hétérogène et mobile et le besoin de satisfaire la QoS de bout en bout, les ressources services doivent être prises en compte au même titre que les ressources réseaux. Donc, un degré élevé d'autosuffisance, d'autogestion et d'automatisation est demandé dans la ressource service (composant de service) pour améliorer le service delivery. Pour cela, nous proposons un composant de service autonomique "ASC: Autonomic Service Component" basé sur un agent de QoS intégré qui s'autocontrôle et s'autogère pour adapter dynamiquement ses ressources en réponse à un changement de situations au cours de la session de l'utilisateur. Notre troisième proposition couvre le modèle protocolaire. La session de services personnalisés nécessite des interactions plus flexibles au niveau service pour avoir une session unique avec une continuité de service. Nous proposons un protocole de signalisation SIP+ qui permet la négociation de la QOS des services personnalisés dès la phase d'initialisation de la session et de la renégociation de la QoS pendant l'usage, pour maintenir le service avec la QoS requise à travers une session unique.De façon plus concrète, nous présentons nos expérimentations à travers un scenario et une plate-forme de démonstration qui nous permet de tester la faisabilité et la performance de nos contributions. Les apports et les perspectives de cette thèse sont consignés en conclusion.

Pour couvrir tout impact de mobilité, nous avons ensuite proposé un " cross layer E2E Session Binding" au sein de notre architecture à quatre niveaux de visibilité (Equipement, Réseau, Service et User). Par le binding nous assurons la cohérence des informations entre les quatre niveaux de visibilité. Au-delà du binding, notre contribution sur la dimension informationnelle a porté sur les profils impliqués dans chaque étape du cycle de vie du service incluant les critères de QoS, les quels fournissent une image générique des composants du système de l'utilisateur et de toutes les ressources ambiantes. Finalement, nous montrons la faisabilité de nos contributions à travers des expérimentations sur notre plate-forme.

Abstract:
Abstract Microbes are omnipresent, yet their interactions with invasive plants remain understudied. This is surprising, given the importance of microbes in plant community ecology and their influence on plant performance in new environments. Recent advances in molecular genetic approaches have opened the door to studying this unseen majority in great detail and to understand how they fit into ecological interaction networks. Molecular approaches allow rapid assessments of microbial diversity at reasonable cost while providing both taxonomic and evolutionary information. Here I discuss how these approaches have contributed to a better understanding of plant-microbial interactions in the context of biological invasions. By drawing insights from various case studies, I illustrate how next-generation sequencing (DNA barcoding) has revolutionized the way we understand such interactions. Tight-knit and coevolved mutualist (e.g. mycorrhizal) and antagonist (e.g. pathogen) interactions appear particularly promising to understand the structure and function of invasive plant-microbial interaction networks, the impacts of invasive plants on native networks and the vulnerability of native networks to infiltration by non-native species. I also discuss novel ways in which molecular data can aid the study of invasive plant-microbial interactions, such as incorporating phylogenetic data into network analyses to better understand the role of evolutionary history in network dynamics and how such dynamics respond to plant invasions. DNA barcoding of microbes also presents unique challenges to the study of network ecology, such as uncertainty in the legitimacy and efficiency of interactions. Future research should incorporate overall plant-associated microbial communities (microbiomes) into interaction networks to better understand the role microbes play during plant invasions.

DeVivo, Joseph C. Inventories 2.0: A plan for the next generation of NPS natural resource inventories. National Park Service, 2019. http://dx.doi.org/10.36967/2266646.

Full text
Abstract:
This Inventory 2.0 plan identifies IMD’s planned role in each of the ten inventories, and lays out a framework for ensuring the inventories led by IMD result in scientifically credible information for parks resource management, planning, and operations; and also identifies the means by which studies to collect new inventory data will be identified, prioritized, and implemented. Highlights include: IMD plans to lead three of the ten inventories (Species, Vegetation Community Mapping, and Surficial Geology/Soils Mapping), and contribute to the others in partnership with other programs. For the three IMD-led inventories, IMD will develop (or work with the Geologic Resources Division to develop) peer-reviewed inventory science plans that will lay out inventory objectives; and methods for data management, analysis, and integration to ensure that credible and useful inventory data are provided to parks in a timely manner. IMD will phase in implementation of IMD-led inventories during the first five years of program implementation. This will allow IMD to focus near-term efforts on meeting needs identified by the greatest number of parks (Species) while conducting necessary scoping to further refine needs for Vegetation Community Mapping and Surficial Geology/Soils Mapping inventories. During the next two years, IMD inventory efforts will be focused on implementing the Species Inventory, beginning with foundational work in advance of field data collection efforts to be funded in 2020. Additional scoping to identify suitable methods and minimum product specifications for Vegetation Community and Surficial Geology/Soils Mapping will be conducted in 2019-2020. These two new inventories will be phased in based on findings from scoping and progress toward closing out existing (1.0) inventory efforts. All I&M parks will be eligible for IMD funding to support inventories (see Appendix A). Non-I&M parks established before 2000 may be eligible for studies and activities to collect new inventory data pending approval of the project by the IMD Leadership Team. Inventories 2.0 funding cannot be spent to collect new data in parks established in 2000 or later, that are not currently served by an I&M network. Existing data from other sources may still be synthesized and delivered to these parks, however. Inventories 2.0 funding will not be used to fund programs or initiatives already funded or implemented by other programs or agencies. We will endeavor to partner with these entities when possible and appropriate to meet inventory needs identified in this plan, and to ensure IMD-created inventory (and monitoring) data are available to support other programs. Data and other information products resulting from new IMD-funded inventory studies will be managed by IMD rather than third-party repositories. This does not preclude sharing data with third parties or use of third-party tools or data distribution systems. At a minimum IMD commits to make inventory data available to others via the NPS Data Store (https://irma.nps.gov/DataStore/) as well as data and/or map services. To the extent possible, IMD management of inventory data will use the data management infrastructure used for managing monitoring data. This includes a commitment to leverage data, tools, systems, and expertise where it already exists. Because of IMD’s explicit mandate to integrate I&M data with planning, wherever practicable, IMD commits to work with NPS Planning to ensure map and data services are integrated into NPS Atlas projects for each park or other planning tools as they are developed over time.

Abstract:
The Pacific Earthquake Engineering Research Center (PEER) is a multi-institutional research and education center with headquarters at the University of California, Berkeley. PEER’s mission is to (1) develop, validate, and disseminate performance-based engineering (PBE) technologies for buildings and infrastructure networks subjected to earthquakes and other natural hazards, with the goal of achieving community resilience; and (2) equip the earthquake engineering and other extreme-event communities with the 21st -century tools that define the current digital revolution. This reports presents the activities of the Center over the period of July 1, 2017 to June 30, 2018. PEER staff, in particular Grace Kang, Erika Donald, Claire Johnson, Christina Bodnar-Anderson, and Zulema Lara, helped in preparation of this report. Key activities of the past academic year include the following: -Continuation of major projects such as Tall Building Initiative (TBI) and Next Generation Attenuation (NGA) projects, and start of work on the major project funded by the California Earthquake Authority (CEA). The TBI was completed in 2017, and NGA projects are nearing completion soon. -Addition of University of Nevada, Reno (UNR) as a core institution. -Re-establishment of the PEER Research Committee. -Issuing a Request for Proposal (RFP) from TSRP funds and funding 17 projects as a result of this RFP. Together with the ongoing projects, the total number of projects funded in 2017 is 24. -Organization of several workshops focused on Liquefaction, Structural Health Monitoring (SHM), High-Performance Computing (HPC), Bridge Component Fragility Development, Physics-Based Ground Motions, Hybrid Simulation, and Research Needs for Resilient Buildings. -Rollout of TBI seminars and HayWired activities as part of outreach. -Conducting a blind prediction contest with robust participation and instructive findings on current modeling approaches. -Organization of the PEER Annual Meeting with participation of 240 attendees -Continuing participation in board of directors of international organizations such as Global Alliance of Disaster Research Institutes (GADRI) and International Laboratory of Earthquake Engineering (ILEE). Going forward, PEER aims to hold more focused workshops, form new committees, and draw on existing resources and experience on PBE to systematically move towards Resilient Design for Extreme Events (RDEE).
