摘要

针对软件定义网络流量调度的多商品流问题，提出一种基于分段路由的方法。所提方法预先计算所有源—目的节点间的候选路径集合和相应路径的属性，再结合流的各种需求和约束条件设置候选路径的属性应满足的要求，据此筛选得出流的候选路径集合；基于流的候选路径集合简化了软件定义网络中的多商品流模型，降低了求解难度，支持控制器集中控制和各节点自主控制的工作方式，缓解了控制器的可扩展性问题；还讨论了如何满足网络的节能需求，减少可参与流转发的链路数量。性能评估结果表明，所提方法可满足流的各种需求和约束条件，提高网络性能，减轻求解流量调度问题的计算负担。

Abstract

In order to address the multi-commodity flow problem for traffic scheduling in software-defined networking

a method based on segment routing was proposed.The proposed method pre-computed sets of candidate paths and attributes of these paths for all source-target nodes

and set the requirements of attributes of candidate paths that should be met combined with various demands and constraints of flows

then generated sets of candidate paths for flows.In the proposed scheme

multi-commodity flow model in software-defined networking was simplified based on sets of candidate paths for flows

the difficulty of solving was reduced

the centralized control by the controller and the autonomous control by nodes were supported

the scalability of controller was improved.In addition

how to meet the energy-saving needs of the network was proposed

i.e.

reducing the number of links that could participate in flow forwarding.The performance evaluation results indicate that the proposed method can meet various demands and constraints of flows

improve network performance

and reduce the computational load of solving the problem of traffic scheduling.
