Design and development of smart and open virtualized communication environments

从2013年到2017年，IT云服务的复合年增长率(CAGR)预计将达到近25%(IDC预测)。为了跟上这种快速发展的步伐，服务和网络提供商必须拥有高效的机制和工具来简化资源调配和管理，同时最大限度地减少资本和运营支出。事实上，云服务正在从预定义向按需和用户驱动的配置演变。由于传统网络有许多限制，云服务环境应该具有显著的可扩展性、可靠性和成本效益。软件即服务(SaaS)、平台即服务(PaaS)和基础设施即服务(IaaS)越来越多地被考虑来实现这些云环境目标。然而，在定义此类公共云环境的解决方案时，需要考虑几个挑战。其中，我们可以列出支持基于服务级别协议(SLA)的资源分配、资源扩展、资源可用性、资源监控和恢复的机制的定义和验证，以支持通过公共云进行动态、高效和按需的资源调配，使提供商和客户都满意。该研究计划解决与分布式虚拟通信环境中的资源配置和管理相关的极具挑战性的问题。将开发新的机制和工具，以便在这些环境中灵活有效地提供和管理网络和服务。将开发新的数学模型和算法，旨在满足虚拟通信环境的多个目标。还将开发新的机制，通过虚拟通信环境的联合整合资源的配置、供应和优化。这项研究计划将提供新的方法，简化向开放和可互操作的通信环境的迁移，同时满足提供商和客户的期望。

IT cloud services are expected to have a compound annual growth rate (CAGR) of almost 25% each year from 2013 to 2017 (IDC forecast). In order to keep up with this rapid evolution, it is essential for service and network providers to have efficient mechanisms and tools that simplify resource provisioning and management while minimizing capital and operational expenditures. In fact, cloud service is evolving from predefined to on-demand and user-driven provisioning. Because legacy networks have many limitations, cloud service environments should be significantly scalable, reliable and cost effective. Software as a service (SaaS), Platform as a service (PaaS) and Infrastructure as a service (IaaS) are increasingly considered to achieve these cloud environment objectives. However, there are several challenges that need to be considered when defining solutions for such public cloud environment. Among them, we can list definition and validation of mechanisms that enable service level agreement (SLA)-based resource allocation, resource scaling; resource availability; resource monitoring and recovery to support dynamic, efficient and on-demand resource provisioning over public cloud where both providers and customers are satisfied. This research program addresses very challenging issues related to resource provisioning and management in distributed virtualized communication environments. New mechanisms and tools will be developed to enable flexible and efficient networks and services provisioning and management within these environments. New mathematical models and algorithms will be developed that aim at satisfying multiple objectives of virtualized communication environments. New mechanisms will be also developed that integrate configuration, provisioning and optimization of resources through federation of virtualized communication environments. This research program will provide novel approaches that ease the migration towards open and interoperable communication environments while satisfying both providers and customer expectations.
