Who Gets in the Way of Parallelism? Analysis and Optimization of the Parallel Processing Bottleneck of SDN Flow Rules in ONOS
Software-Defined Networking (SDN) decouples the data plane from the control plane, enabling centralized control and open programmability of the network. OpenFlow flow rules are the key carrier for the SDN application to configure and manage the data plane through the control plane, and the processing efficiency of flow rules of the SDN controller in the control plane is critical as it will directly impact the instantaneity of configuring and managing the data plane. Currently, the controller increases the processing efficiency of flow rules by means of multi-threaded parallel processing. However, in the experiments of the widely used SDN controller ONOS, we found a new bottleneck in the parallel processing of flow rules that causes the performance gains from parallelism to be offset. Therefore, in this paper, we locate the bottleneck and analyze its causes through source code analysis and timestamp tests, propose a parallel event queue to resolve the bottleneck, and implement it in ONOS. Experiments show that our improved ONOS effectively resolves the bottleneck problem and achieves an average 3.57x improvement in the processing efficiency of flow rules compared to the original ONOS.
期刊介绍:
Computer Supported Cooperative Work (CSCW): The Journal of Collaborative Computing and Work Practices is devoted to innovative research in computer-supported cooperative work (CSCW). It provides an interdisciplinary and international forum for the debate and exchange of ideas concerning theoretical, practical, technical, and social issues in CSCW.
The CSCW Journal arose in response to the growing interest in the design, implementation and use of technical systems (including computing, information, and communications technologies) which support people working cooperatively, and its scope remains to encompass the multifarious aspects of research within CSCW and related areas.
The CSCW Journal focuses on research oriented towards the development of collaborative computing technologies on the basis of studies of actual cooperative work practices (where ‘work’ is used in the wider sense). That is, it welcomes in particular submissions that (a) report on findings from ethnographic or similar kinds of in-depth fieldwork of work practices with a view to their technological implications, (b) report on empirical evaluations of the use of extant or novel technical solutions under real-world conditions, and/or (c) develop technical or conceptual frameworks for practice-oriented computing research based on previous fieldwork and evaluations.
