Modern cloud computing systems use virtual machine technologies to deliver unprecedented flexibility to users, enabling businesses and individuals to cost-effectively deploy computing and storage capacity on-demand, at scale, across multiple infrastructures distributed geographically. While the ability to deploy virtual machines for cloud computing is widely supported, researchers face increasing challenges in prototyping and deploying experimental research systems that span across multiple cloud providers. In particular, providing end-to-end network connectivity among distributed virtual machines in today's Internet environment (where nodes are often constrained by firewalls and network address translators) requires significant investment of time in development, testing and maintenance of code needed solely to provide connectivity. This project addresses these connectivity challenges in cloud computing by developing an open-source scientific software element that allows researchers and users of clouds to seamlessly create virtual networks on demand for distributed virtual machines. To this end, the project creates software-defined virtual networks that support the standard Internet Protocol (IP) and use tunneling of virtual network packets over Peer-to-Peer (P2P) links among virtual machines for scalable and resilient messaging. In addition to the core IP-over-P2P virtual networking, the software provides a framework for configuration, management and monitoring that enables easy deployment of user-defined overlays for inter-cloud research experiments. The open-source software developed in this project enables advances in the state-of-the-art of research of cloud computing systems and applications. Complementary to research and development activities, this project delivers educational modules, tutorials, software packages, and pre-configured virtual machine images that allow non-expert users to deploy their own virtual networks over private, commercial and public clouds. Because cloud computing technologies are increasingly pervasive and of growing importance to the economy and society, the broader impacts of this project can reach Internet users at large who benefit from the ability to seamlessly interconnect cloud virtual machines across multiple providers. In particular, leveraging online social networking technologies, the virtual network software software enables individuals and small groups to easily create social virtual private networks connecting personal computers and multiple cloud resources.

现代云计算系统使用虚拟机技术为用户提供前所未有的灵活性，使企业和个人能够在分布的多个基础架构上按需以成本效益的计算和存储能力在单位上进行按需分配。尽管广泛支持虚拟机进行云计算的虚拟机的能力，但研究人员面临着跨越多个云提供商的实验研究系统的原型挑战。特别是，在当今的Internet环境中（通常受防火墙和网络地址转换器的限制）在分布式虚拟机之间提供端到端网络连接，需要大量的时间投资于开发，测试和维护代码，仅需提供连接性所需的代码。该项目通过开发一个开源科学软件元素来解决云计算中的这些连接挑战，该元素允许云的研究人员和用户无缝地按需为分布式虚拟机创建虚拟网络。为此，该项目创建了支持标准Internet协议（IP）的软件定义的虚拟网络，并在虚拟机之间使用虚拟网络数据包（P2P）链接使用虚拟网络数据包，以进行可扩展和弹性消息传递。除了核心IP-ever-P2P虚拟网络外，该软件还提供了用于配置，管理和监视的框架，可轻松部署用户定义的叠加层进行云间研究实验。 该项目中开发的开源软件可以在云计算系统和应用程序的最新研究中进步。该项目对研发活动的补充，提供教育模块，教程，软件包和预配置的虚拟机映像，这些虚拟机映像使非专家用户可以通过私人，商业和公共云部署自己的虚拟网络。由于云计算技术越来越普遍，并且对经济和社会的重要性越来越重要，因此该项目的更广泛影响可以吸引互联网用户，他们从多个提供商中无缝互连云虚拟机器的能力受益。特别是利用在线社交网络技术，虚拟网络软件软件使个人和小组可以轻松地创建连接个人计算机和多个云资源的社交虚拟专用网络。
