Green Segment Routing

从经济和生态的角度来看，信息技术资源的优化利用是一个重要的挑战。在电信领域，解决这类挑战的研究被称为流量工程。本项目以能源优化为目标，解决了单个自主系统的交通工程问题。这个目标是通过使用段路由来实现的。通过使用段路由，数据包可以通过网络中的某些控制点来控制。我们认为分段路由是完全控制和简单最短路径之间的折衷，可以在实际网络中实现。在这个项目中，我们将通过使用分段路由来开发流量工程策略。优化的主要目标是能源效率，但不损害网络的鲁棒性。一个基本的挑战是计算精确解的复杂性。在我们之前的工作中，我们已经意识到在考虑现实世界约束的典型拓扑上通过分段路由的流量工程接近实际可计算性。如果我们把能源效率作为一个额外的限制，我们会看到在实际场景中计算精确解决方案的巨大挑战。因此，在这个联合项目中，我们将以能效为目标，进行算法研究和分段路由的实用性研究。

The optimal utilization of IT resources is an important challenge from an economic as well as an ecological viewpoint. In the area of telecommunications, research that addresses such challenges is called traffic engineering. This project addresses traffic engineering for single autonomous systems with the goal of energy optimization. This goal is approached by the use of segment routing. By using segment routing, packets can be steered via certain control points within a network. We see segment routing as a compromise between full control and simple shortest paths that can be implemented in practical networks. In this project, we will develop traffic engineering strategies by using segment routing. The main goal of the optimizations is energy efficiency, but without jeopardizing the robustness of the network. One fundamental challenge is the complexity to calculate exact solutions. Within our previous work, we have realized that traffic engineering via segment routing on typical topologies considering real-world constraints is close to practical computability. If we add energy efficiency as an additional constraint, we see big challenges in calculating exact solutions for practical scenarios. Thus, in this joint project, we will conduct algorithmic research as well as research on the practical applicability of segment routing with the goal of energy efficiency.
