power saving processing method and System for mobile terminal and mobile terminal
2010Co-Authors: Mou Lunrong, Xia Jun, Tang Bo, Wan BingAbstract:The invention discloses a power-saving processing method and System for a mobile terminal, and the mobile terminal. According to the power-saving processing method, tasks of a baseband subSystem are scheduled and processed prior to tasks of an application subSystem, so the tasks of the baseband subSystem with high real-time requirements are processed in time; when no tasks of the application subSystem are ready, the application subSystem is in a dormant state, on the basis, if no tasks of the baseband subSystem are ready, the baseband subSystem is enabled to enter a sleep state, so the power consumption of the mobile terminal is reduced, and the usage time is prolonged; as a Virtual Operating System is introduced, the communication between the baseband subSystem and the application subSystem is realized, both the baseband System and the application subSystem can by operated by one processor, and the production cost is reduced.

An architecture model for a distributed Virtualization System
International Academy Research and Industry Association (IARIA), 2018Co-Authors: Pessolani Pablo, Tinetti Fernando, Cortés Toni, Gonnet SilvioAbstract:This article presents an architecture model for a Distributed Virtualization System, which could expand a Virtual execution environment from a single physical machine to several nodes of a cluster. With current Virtualization technologies, computing power and resource usage of Virtual Machines (or Containers) are limited to the physical machine where they run. To deliver high levels of performance and scalability, cloud applications are usually partitioned in several Virtual Machines (or Containers) located on different nodes of a Virtualization cluster. Developers often use that processing model because the same instance of the Operating System is not available on each node where their components run. The proposed architecture model is suitable for new trends in software development because it is inherently distributed. It combines and integrates Virtualization and Distributed Operating Systems technologies with the benefits of both worlds, providing the same isolated instance of a Virtual Operating System on each cluster node. Although it requires the introduction of changes in existing Operating Systems, thousands of legacy applications would not require modifications to obtain their benefits. A Distributed Virtualization System is suitable to deliver high-performance cloud services with provider-class features, such as high-availability, replication, migration, and load balancing. Furthermore, it is able to concurrently run several isolated instances of different guest Virtual Operating Systems, allocating a subset of nodes for each instance and sharing nodes between them. Currently, a prototype is running on a cluster of commodity hardware provided with two kinds of Virtual Operating Systems tailored for internet services (web server) as a proof of concept.Toni Cortes’ involvement in this work was financially supported by the Spanish National Government (financial grant SEV2015-0493 of Severo Ochoa program), the Spanish Ministry of Science and Innovation (contract TIN2015-65316), and the Government of Catalonia (contract 2014-SGR-1051).Fernando G.

An Architecture Model for a Distributed Virtualization System
2019Co-Authors: Pessolani, Pablo AndrésAbstract:Virtualization technologies are massively adopted to cover those requirements in which Operating Systems (OS) have shown weakness, such as fault and security isolation. They also add features like resource partitioning, server consolidation, legacy application support, management tools, among others, which are attractive to Cloud service providers. Hardware Virtualization, paraVirtualization, and OS-level Virtualization are the most widely used technologies to carry out these tasks, although each of them presents different levels of server consolidation, performance, scalability, high-availability, and isolation. The term “Virtual Machine” (VM) is used in issues related to hardware Virtualization and paraVirtualization technologies to describe an isolated execution environment for an OS and its applications. Containers, Jails, Zones are the names used in OS-level Virtualization to describe the environments for applications confinement. Regardless of the definition of the Virtualization abstraction, its computing power and resource usage are limited to the physical machine where it runs. The proposed Virtualization architecture model breaks this issue, distributing processes, services, and resources to provide distributed Virtual environments based on OS factoring and OS containers. The outcome is a Distributed Virtualization System (DVS) which allows running several distributed Virtual Operating System (VOS) on the same cluster. A DVS also fits the requirements for delivering high-performance cloud services with provider-class features as high-availability, replication, elasticity, load balancing, resource management, and process migration. Furthermore, a DVS is able to run several instances of different guest VOS concurrently, allocating a subset of nodes for each instance (resource aggregation), and to share nodes between them (resource partitioning). Each VOS runs isolated within a Distributed Container (DC), which could span multiple nodes of the DVS cluster. The proposed architecture model keeps the appreciated features of current Virtualization technologies, such as confinement, consolidation and security, and the benefits of DOS, such as transparency, greater performance, high-availability, elasticity, and scalability.Este documento es la reseña de una tesis publicada en Sedici (ver documento relacionado).Facultad de Informátic
