This Trilogy 2 project is a 3-year Small or medium-scale focused research project (STREP) targeting Challenge 1 of the 7th FrameworkProgramme: "Pervasive and Trusted Network and Service Infrastructures".The project scope lies entirely within Objective 1.1, "Future Networks"and in particular in bullet c) Novel Internet architectures, management and operation frameworks.The aim of the project is to develop a new Internet architecture based on the concept of the liquid network. A liquid system should ideally allow resources including bandwidth, storage and processing to be used by any application, whether they are contributed by network operators, data centre operators or end systems. Resources form a shared pool and applications can scale up and down in multiple dimensions (storage, processing, bandwidth and energy usage) as needed, in a continuous effort to enhance the users' experience as measured in terms of key metrics such as delay and battery life.The main objective of Trilogy 2 is to unlock the value inherent in joining up the pools of liquidity in the Internet. The project will develop more mature liquidity mechanisms addressing the underlying reasons why today liquidity fails to join up across providers, layers and resources. Trilogy 2 will deliver mechanisms for creating liquidity across different types of resources, including cross layer liquidity, cross provider liquidity and cross resource liquidity. In addition, in order to allow the different stakeholders to be willing to create such liquid pools of resources, Trilogy 2 will also provide the means to control the created liquidity though the means of incentives, information exchange and enforcement tools. Finally, Trilogy 2 will use the novel liquidity mechanisms to enable a set of compelling use cases targeting mobile devices and ISP's network infrastructure.
