Linux XIA: an interoperable meta network architecture to crowdsource the future internet

Abstract

With the growing number of proposed clean-slate redesigns of the Internet, the need for a medium that enables all stakeholders to participate in the realization, evaluation, and selection of these designs is increasing. We believe that the missing catalyst is a meta network architecture that welcomes most, if not all, clean-state designs on a level playing field, lowers deployment barriers, and leaves the final evaluation to the broader community. This paper presents Linux XIA, a native implementation of XIA [12] in the Linux kernel, as a candidate. We first describe Linux XIA in terms of its architectural realizations and algorithmic contributions. We then demonstrate how to port several distinct and unrelated network architectures onto Linux XIA. Finally, we provide a hybrid evaluation of Linux XIA at three levels of abstraction in terms of its ability to: evolve and foster interoperation of new architectures, embed disparate architectures inside the implementation's framework, and maintain a comparable forwarding performance to that of the legacy TCP/IP implementation. Given this evaluation, we substantiate a previously unsupported claim of XIA: that it readily supports and enables network evolution, collaboration, and interoperability -traits we view as central to the success of any future Internet architecture.

“…Selforganization and contract-based operation are important for future energy distribution scenarios, in which convergence of traditional and decentralized energy generation meet. Besides NovaGenesis, other architectures such as expressive Internet architecture (XIA) [286], [287] and recursive Internet architecture (RINA) [288] have the potential to be used in telecommunications networks for energy area. XIA defines a novel expressive Internet protocol (XIP) already implemented in the Linux core.…”
