Multimedia applications and services continue to play a crucial role in daily and business life. They have evolved from predefined to on-demand provisioning. Cloud computing paradigm and different network infrastructures have been identified as promising candidates to support this on-demand service vision. Cloud computing provides infrastructure, platform and software as a service to ease consolidation and sharing of resources (software and hardware resources) by different applications while reducing cost and speeding time to market for new services. Several network infrastructures have been identified as promising candidates to support this on-demand service vision. Virtualizing these infrastructures improves the system scalability, simplifies software upgrade, eases the implementation of security and reduces the cost of Capital Expenditure and Operating Expense. However, defining and validating mechanisms that enable dynamic resource management over network function virtualization infrastructures, while meeting the requirements of different entities (Consumers, platform providers and infrastructure providers) remain a big challenge. The main objective of this proposal is to define and validate novel mechanisms (e.g., models, algorithms and methodologies) to support dynamic resource management for virtualized network functions through efficient and fine-grained resource provisioning while satisfying Service Level Agreements (SLAs). Unlike the existing solutions, these approaches will react to various dynamic virtualized network functions with no prior knowledge of their internal designs, and therefore will enable generic, efficient and flexible resource management. The proposed research activities will help reduce physical infrastructure cost, energy consumption and time to market for new application deployment; 2) adding more flexibility for network and service management; 3) offering an open service platform for multiple players and business roles. Moreover, dynamic and SLA-based resource management solutions for virtualized network functions will be implemented and deployed as proof-of-concept. ********

多媒体应用和服务继续在日常和商业生活中发挥着至关重要的作用。它们已经从预定义的配置发展到按需配置。云计算范例和不同的网络基础设施已被确定为支持这种按需服务愿景的有前途的候选者。云计算提供基础设施、平台和软件即服务，以简化不同应用程序的资源（软件和硬件资源）整合和共享，同时降低成本并加快新服务的上市时间。几个网络基础设施已被确定为有前途的候选人，以支持这种按需服务的愿景。虚拟化这些基础设施可以提高系统的可扩展性，简化软件升级，简化安全性的实施，并降低资本支出和运营成本。然而，定义和验证能够在网络功能虚拟化基础设施上实现动态资源管理的机制，同时满足不同实体（消费者、平台提供商和基础设施提供商）的要求仍然是一个很大的挑战。本提案的主要目标是定义和验证新机制（例如，模型、算法和方法），以通过高效且细粒度的资源供应来支持虚拟化网络功能的动态资源管理，同时满足服务水平协议（SLA）。与现有的解决方案不同，这些方法将对各种动态虚拟化网络功能做出反应，而无需事先了解其内部设计，因此将实现通用、高效和灵活的资源管理。拟议的研究活动将有助于降低物理基础设施成本、能源消耗和新应用程序部署的上市时间; 2）增加网络和服务管理的灵活性; 3）为多个参与者和业务角色提供开放的服务平台。此外，将实施和部署用于虚拟化网络功能的动态和基于SLA的资源管理解决方案，作为概念验证。********
