Scheduling Design for Advance Virtual Network Services

Bai, Hao 16 November 2016 (has links)
Network virtualization allows operators to host multiple client services over their base physical infrastructures. Today, this technique is being used to support a wide range of applications in cloud computing services, content distribution, large data backup, etc. Accordingly, many different algorithms have also been developed to achieve efficient mapping of client virtual network (VN) requests over physical topologies consisting of networking infrastructures and datacenter compute/storage resources. However as applications continue to expand, there is a growing need to implement scheduling capabilities for virtual network demands in order to improve network resource utilization and guarantee quality of service (QoS) support. Now the topic of advance reservation (AR) has been studied for the case of scheduling point-to-point connection demands. Namely, many different algorithms have been developed to support various reservation models and objectives. Nevertheless, few studies have looked at scheduling more complex "topology-level'' demands, including virtual network services. Moreover, as cloud servers expand, many providers want to ensure user quality support at future instants in time, e.g., for special events, sporting venues, conference meetings, etc. In the light of above, this dissertation presents one of the first studies on advance reservation of virtual network services. First, the fixed virtual overlay network scheduling problem is addressed as a special case of the more generalized virtual network scheduling problem and a related optimization presented. Next, the complete virtual network scheduling problem is studied and a range of heuristic and meta-heuristic solutions are proposed. Finally, some novel flexible advance reservation models are developed to improve service setup and network resource utilization. The performance of these various solutions is evaluated using various methodologies (discrete event simulation and optimization tools) and comparisons made with some existing strategies.

Aplikace pro rezervaci vstupenek v IMS / Application for the reservation of tickets in the IMS

Otoupalík, Pavel January 2010 (has links)
This master’s thesis deals description of the IMS (Internet Protocol Multimedia Subsystem) and shows the possibility for design applications that using services this system. The theoretical part of the thesis is focused on a detailed description of the IMS architecture, its key components and the SIP protocol that is main signaling protocol in the IMS. The practical part of the work describes the design, implementation and test of the system for reservation of tickets to cinema in the IMS. The project was created as client-server application in the development studio SDS Ericsson 4.1 FD1 with built-in IMS simulator. The client application is designed for mobile devices with support of the J2ME platform. The server part of the system is realized as SIP Servlet with access to the MySQL database. In the database are saves records about registered users, offered tickets and successful reservation. For easy work over MySQL database of the system for reservation of tickets was created the application for its administration in the Java programming language (Java SE 6). With the assistance of this application, the operators of system can add and erase the records about films, time projection and disburse tickets on the basis of knowledge of reservation ID. In the end of the work is realized SIP signaling analysis of the client registration to IMS and communication between the client application and the SIP Servlet.

Availability-Aware Resource Allocation for Containerized Network Functions

Huang, Zhuonan 31 May 2021 (has links)
Deploying virtual network functions (VNFs) such as WAN accelerators, network address translators (NATs) and 5G functions at the network edge (NE) can significantly reduce the experienced latency of delay-ultrasensitive applications (e.g., autonomous vehicles and Internet of things). Nonetheless, a major challenge to their anticipated large-scale deployment is the ability to efficiently allocate and manage the scarce NE resources hosting these functions. In this thesis, we describe a novel containerized infrastructure manager (cIM) that extends current managers, such as Kubernetes, with the necessary building blocks to provide an accurate yet elastic resource allocation service to containerized VNFs at scale. The proposed cIM treats the main modules of the VNFs, i.e., the containerized VNF components (cNFCs), as atomic special-purpose functions that can be rapidly deployed to form complex network services. The main component of the proposed cIM, the resource reservation manager (RRM), employs concepts of risk pooling in the insurance industry to accurately reserve the needed resources for the hosting containers. More precisely, to meet anticipated cNFCs demand fluctuation, the RRM accurately reserves a quota of additional resources that are shared by the containerized functions collected together in clusters. The reserved quota of resources ensures the desired availability level of the cNFCs without over-provisioning the scarce resources of the NE. The RRM considers three different situations namely that of a cNFC instance, a cluster of cNFCs or multiple cNFC clusters sharing the reserved resources. Different allocation approaches are then presented for each of these three situations. Simulation experiments are conducted to evaluate the performance of our reservation schemes from different aspects. The corresponding experimental results demonstrate that our proposed cIM can significantly improve the performance of the cNFCs and guarantee their desired availability with minimal resource reservation. Optimal allocation solutions of the resource pools are further proposed considering the desired availability level and the limit of resource pools. The evaluation results demonstrate that our optimization models and solutions obtain the best performance of relevant testing parameters, e.g., availability.

Plant Community Composition of Camp Grafton Training Center (South Unit) from 1998-2013

O'Brien, Peter January 2014 (has links)
A vegetation monitoring study was conducted from 1998 to 2013 at Camp Grafton South (CGS) in Eddy County, North Dakota to assess how climatic, grazing, and military training disturbance affects plant community composition. The objectives of this study were to 1) describe the prairie vegetation at CGS across three topographic positions and 2) explore any shifts in plant community composition in correlation with time. Frequency data was collected at 45 randomly selected transects on lowland, midland, and upland grassland plant communities on native prairie. Plant communities were compared using non-metric multidimensional scaling (NMS) ordination. NMS ordination showed that the three plant communities were distinct from one another, and that the frequency of the invasive graminoids Kentucky bluegrass (Poa pratensis L.) and smooth brome (Bromus inermis Leyss.) increased. Increases in precipitation, temperature, and growing season days appear to be the primary influence on the changes in plant communities from 1998-2013.

Dům pro handicapované v jádru městské památkové rezervace / The house for the handicapped people in the centre of town listed reservation

Konvičný, Tomáš January 2010 (has links)
The subject of this diploma thesis is a project of a building for handicapped people. This building is set into the historic center of the urban conservation area in Lipník nad Bečvou. The site for the building has a rectangular plan in view and is situated on the edge of the southern row of houses on the T.G.M. square and the western row of houses of Křížkovského street. The conditions for the building of the house in a view of the conservation care: - the house has maximally two floors - the plan in view must respect the street line - the roof must be inclined - wooden windows and doors - lime plaster The mass solution is based on the concept of the ending of both present street faces, whose heights are very different. The part of the building which faces towards the square, fulfils the condition of two floors building and thus in the long distance view from the square it does not eclipse the skyline of the bell tower and St. Jacob´s church. The higher part of the house follows the currently standing house in Křížkovský street, it makes a second plan impression and it does not disturb the long distance view. The southern orientation of the taller part contributes to a good sunlit of the inner space and the taller height enables a better use of the building plot. Both masses are connected by a part with the eastern orientation which is sunk in the view of the base line and so it enables to make he space for placing the ramp and two stanby parking places. The building is partly two-floored and partly four-floored with one floor in the underground. In the grand floor there is placed six parking places, technical background and storage rooms. The vertical transport is provided by both personal and freight lifts, the inner staircase a set forth ramp and one direction ramp for cars, which is controlled by trafic lights. In the first floor there are: 2 commercially useful spaces with backgrounds, a freight ramp for materials and workshop products transport and a waste storage. In the second floor there are a workshop with backgrounds (office, storage room, daily room, cloakroom and bathroom) and a flat (103 m2). In the third floor there are two flats (79 m2) and (49 m2). In the fourth floor there is a flat (79 m2). The construction of the house is monolytic, made of steel and concrete. It is made of basal belts, footing, peripheral supporting walls, bearers and ceiling boards. The dividing walls are concrete. The concrete construction is like a view from the inner space and from the other space. It is warmed with mineral fiberglass, which is covered with a retaining hydroisolation and cement facing with a lime plaster. This everything is hung on an aluminium profiles grid. In the ground floor, the fillings of the slots are aluminium eloxed in an anthracite grey colour. In the other floors They are made of wood with a wooden facing. The roof construction is made of a wooden bond which is put on a steel and concrete construction. The roof case is ventilated and there are aluminium eloxed folded templates.

Targeting Nonindustrial Private Forest Landowner Groups for Timber Market Entry

Conway, M. Christine 10 March 2003 (has links)
This study models the timber market entry decisions of nonindustrial private landowners. It involves examining reservation prices both for harvesting timber from existing forest land and for afforestation of marginal agricultural and abandoned land. An important conclusion drawn from these models is that financial returns are not the only drivers of these decisions. Preferences for amenities derived from forests and farmland are also important. An empirical model follows which characterizes willingness to accept for various landowner groups in Virginia and Mississippi. We identify preferences and characteristics of landowners and features of forest sites that are important to the unobserved price specific to each landowner. Estimation results are also used to assess the size of payments needed to encourage harvesting or conversion from agricultural to forest uses with 50% probability. The determination of reservation prices for landowners in different regions aids in forecasting potential timber supplies from NIPF lands that are either actively managed for timber production or are not, as well as from marginal land not yet in forests, under different policy and pricing scenarios. Furthermore, it gives insight into evolving land use patterns. / Ph. D.
