SFB 1053: MAKI - Multi-Mechanism-Adaptation for the Future Internet

未来的互联网会是什么样子？哪些通信形式--我们今天所知的--将会占上风，哪些新的通信形式将会出现？随着移动网络使用量的不断增加，您面临哪些挑战？总而言之：通信系统中的一个重大挑战来自于其运行条件的动态和变化的增加，用例的不断增加的变化量，以及不断增长的质量要求。合作研究中心MAKI(多机制-适应未来互联网)应对这一挑战。具体地说，它研究了通信系统中的各种机制，以及它们的适应、交互、不断优化和演化。术语机制描述了通信协议及其部分--定义了通信系统的功能--以及在上面实现的分布式系统的功能方面。我们见证了新机制的不断发展。然而，由于传统机制对业务条件、带宽等的适应是有限的，所以在不同条件下提供等价功能的机制是相同的。特别是移动使用会引起高度波动的情况，这将需要通过在功能相同的机制之间的过渡来在线适应通信系统--这在今天几乎是不可能的。相互依赖的机制之间的相互作用更加复杂，需要在一组等价机制中进行协调转换，即所谓的多机制适应。CRC的目标是在运行时实现通信系统中功能等价机制之间的自动转换。它包括相互影响的多个并发转换的协调。我们在面向“未来互联网”的国际研究努力的背景下面临着这一挑战。我们认为，机制的大量共存是刺激创新的大好机会，而不是诅咒。然而，需要在研究方面取得重大进展，才能在系统运行时实现机构之间的单独以及联合协调(多)转换。我们的目标是全球互联网研究的范式转变。我们认为，需要有针对性地做出给定CRC规模的努力，以应对互联网日益增长的复杂性、变化性和动态化，这些变化与新应用的泛滥和不断提高的质量要求相吻合。

How will the Internet of the future look like? Which forms of communications – as we know them today – will prevail, which novel forms of communications will emerge? What are the challenges faced regarding the constantly increasing mobile use of networks? To summarize: A grand challenge in communication systems stems from an increase in dynamics and variations of the conditions in which they operate, the constantly increasing amount of changes of use cases, and the growing quality re-quirements. The Collaborative Research Centre MAKI (Multi-Mechanism-Adaption for the Future Internet) addresses this challenge. In par-ticular, it investigates all kinds of mechanisms in communication systems, the adaptation, interaction, constant optimization, and evolution thereof. The term mechanism describes both, communication protocols and parts thereof – defining the func-tionality of communication systems – and the functional aspects of the distributed systems realized on top. We witness a con-stant development of novel mechanisms. Yet, mechanisms providing equivalent functionality under different conditions coex-ist, since an adaptation of legacy mechanisms to traffic conditions, bandwidth, etc. is limited. Particularly mobile usage induces highly fluctuating conditions, which would require the online adaptation of the communication system by means of transitions between functionally equivalent mechanisms – which is mostly impossible as of today. Interactions between mechanisms that jointly depend on each other are more complex still and require coordinated transitions in groups of equivalent mechanisms, so-called multi-mechanisms-adaptation.Goal of the CRC is to enable such automated transitions between functionally equivalent mechanisms in communication sys-tems at runtime. It includes the coordination of multiple concurrent transitions, which influence each other. We face this chal-lenge in the context of the international research efforts towards a “future Internet”. We consider the plentiful coexistence of mechanisms a great opportunity rather than a curse, stimulating innovation. However, significant advances in research are re-quired to enable individually as well as jointly coordinated (multi-) transitions between mechanisms at system runtime. We aim at a paradigm shift in the global Internet research. We believe that a targeted effort of the given CRC-scale size is required to deal with the ever increasing complexity, variability, and dynamics of the Internet that coincide with a deluge of novel applica-tions and constantly increasing quality requirements.
