Today's fluid society is reflected in the choices we make with respect to relationships (such as to service providers or to other users), choices of identities, information we seek and many more issues. End user demands are met in a way that hides an increasingly complex ecosystem of service and facility providers, each of which is driven by their own business needs. In future networks will need to cope with increasing conflicts of interest between users, network operators and service providers (and more) - the concept of tussle. This will require a collaborative negotiation approach that enables simple and flexible arrangement of the components needed to the requirements of the stakeholders, performed in a way which is invisible to the end user.Traditional network design is done in a planned and static manner, reflecting the high investment and long lead times of new network deployments. It involves predicting future requirements, and designing to cater for that vision, following a prescriptive engineering approach. This static design approach is based on incomplete, a priori, information. Outdated solutions can thus reach the market which fail to meet (unpredicted) user needs; market drivers that motivated the initial design may have changed by the time the network is deployed. This has in the past caused certain features and services (that have been invested in and provisioned) to fail, due to lack of post-deployment customer take-up (e.g. mobile video calling). Conversely, other services (e.g. SMS and social networking) have emerged unexpectedly as hugely popular, mainstream applications. Introducing a degree of autonomy into network operation is seen by many as part of the solution, but on its own this may not address operator concern over network reliability and may not support increasing tussle between users, service providers, etc.This provides the motivation to bring together engineering and computer science to explore network technologies which can support the required properties of flexible networks. These include virtualisation, self-*, network coding and multi-homing. , which can provide structural flexibility in a future network, as well as technologies such as overlaying, auto-configuration and dynamic market approaches, which can provide the required control flexibility. Any network which embodies such powerful flexibilities must be trustworthy, in terms of its network composition and future self-evolution, hence novel network verification techniques are also investigated. This ensemble of technologies must be combined, using a novel design methodology, to enable the provision of future flexible, agile, self-evolving, robust and efficient networks that combine an ability to support the somewhat unpredictable needs of the future. A networking paradigm is required that is less prescriptive and enables network self-evolution.The project aims to enable such new networking paradigm and design methodologies for future flexible networks, which need to cope with unpredictable demand patterns, are likely to be self-evolving and will require different properties from those of today. It will create design methodologies that enable flexible networks (networks that are flexible, agile, dynamic, and self-evolving and accommodate tussle).In its first phase the project team will investigate, analyse and develop tools to model the conflicts of interest between stakeholders in future networks. Baseline metrics for network virtualisation and market based resource allocation will be identified and means to ensure robustness and increase efficiency across heterogeneous networks will be investigated. Finally requirements and tools for network verification tools capable to ensure trust and accountability will be defined.This project forms the first phase of the Flexible Networks project, part of the strategic partnership between EPSRC and Mobile VCE.

当今社会的流动性反映在我们对关系（如服务提供商或其他用户）的选择，身份的选择，我们寻求的信息以及更多问题。最终用户需求的满足方式隐藏了日益复杂的服务和设施提供商生态系统，每个提供商都由自己的业务需求驱动。在未来的网络将需要科普用户，网络运营商和服务提供商（以及更多）之间的利益冲突-争斗的概念。这就需要一种合作协商的方法，能够根据利益相关者的要求，以一种对最终用户不可见的方式简单灵活地安排所需的组件。传统的网络设计是以有计划的静态方式进行的，这反映了新网络部署的高投资和较长的交付时间。它涉及预测未来的需求，并按照规定的工程方法进行设计，以满足这一愿景。这种静态设计方法是基于不完整的先验信息。因此，过时的解决方案可能无法满足（无法预测的）用户需求;推动初始设计的市场驱动因素可能在网络部署时发生变化。这在过去已经导致某些功能和服务（已经投资和提供的）失败，这是由于缺乏部署后的客户接受（例如，移动的视频呼叫）。相反，其他服务（如短信和社交网络）出人意料地成为非常受欢迎的主流应用程序。将一定程度的自主权引入网络操作被许多人视为解决方案的一部分，但就其本身而言，这可能无法解决运营商对网络可靠性的担忧，也可能无法支持用户、服务提供商等之间日益增加的争斗。这提供了将工程和计算机科学结合在一起以探索能够支持灵活网络所需属性的网络技术的动机。这些技术包括虚拟化、自 *、网络编码和多宿主。，它可以在未来的网络中提供结构灵活性，以及覆盖，自动配置和动态市场方法等技术，可以提供所需的控制灵活性。任何体现这种强大的灵活性的网络必须是值得信赖的，在其网络组成和未来的自我进化，因此新的网络验证技术也进行了研究。必须使用新颖的设计方法将这些技术组合在一起，以便能够提供未来灵活、敏捷、自我发展、健壮和高效的网络，这些网络联合收割机结合了支持未来某种程度上不可预测的需求的能力。需要一个规范性较低并能使网络自我进化的网络范例。该项目旨在为未来灵活的网络启用这种新的网络范例和设计方法，这些网络需要科普不可预测的需求模式，可能会自我进化，并需要与今天不同的属性。它将创建设计方法，使灵活的网络（网络是灵活的，敏捷的，动态的，自我发展和适应争斗）。在其第一阶段，项目小组将调查，分析和开发工具，以模拟利益相关者之间的利益冲突，在未来的网络。将确定网络虚拟化和基于市场的资源分配的基准指标，并研究确保异构网络的鲁棒性和提高效率的方法。最后，将定义能够确保信任和问责制的网络验证工具的要求和工具。该项目构成了灵活网络项目的第一阶段，是EPSRC和移动的VCE之间战略合作伙伴关系的一部分。
