Abstract Despite the fact that most of the data centers are software-defined, the multifaceted network architecture and increase in network traffic make data centers to suffer from overhead. Multipath TCP supports multiple paths for a single routing session and ensures proper utilization of bandwidth over all available links. As rise in number of nodes in data center is frequent and drastic, scalability issue limits the performance of many existing techniques. Segment Routing is vibrant in reducing scalability disputes and routing overhead. Segment routing approach combined with MPTCP traffic result in efficient routing approach. The downfall of the link capacity due to drastic incoming traffic remains as a major concern in data center network which enforces preventing link energy depletion due to high network traffic. Our proposed work, segment routing based energy aware routing approach for software defined data center aims to achieve throughput maximization through preserving link residual capacity and proper utilization of links. As well, our approach shows a decrease in length of segment label stack with respect to maximum segment label depth. Analysis is done by comparing the executions of other existing approaches in a single-controller environment with our energy-aware routing approach in a distributed environment. Distributed controller setup prevents network from single point of failure. It helps to prevent controller overhead and provides improved network performance through throughput.

用于软件定义数据中心的基于分段路由的能量感知路由

摘要 尽管大多数数据中心是软件定义的，但多方面的网络架构和网络流量的增加使数据中心受到开销的影响。多路径 TCP 支持单个路由会话的多个路径，并确保在所有可用链接上正确利用带宽。随着数据中心节点数量的频繁增加和急剧增加，可扩展性问题限制了许多现有技术的性能。段路由在减少可扩展性争议和路由开销方面充满活力。段路由方法与 MPTCP 流量相结合产生了高效的路由方法。由于大量传入流量导致链路容量下降仍然是数据中心网络中的一个主要问题，数据中心网络强制防止由于高网络流量导致链路能量消耗。我们提议的工作，用于软件定义数据中心的基于分段路由的能量感知路由方法旨在通过保留链路剩余容量和适当利用链路来实现吞吐量最大化。同样，我们的方法显示，相对于最大段标签深度，段标签堆栈的长度有所减少。分析是通过将单控制器环境中其他现有方法的执行与分布式环境中的能量感知路由方法进行比较来完成的。分布式控制器设置可防止网络出现单点故障。它有助于防止控制器开销并通过吞吐量提供改进的网络性能。
