公用事业公司正在将多协议标签交换(MPLS)技术集成到现有的主干网络中，包括变电站和控制中心之间的网络。MPLS具有高效覆盖技术的机制以及增强安全性的机制：这些功能对于智能电网的运行至关重要。然而，对于MPLS路由和其他交换技术，创新被限制在“盒子里”封装的功能上。更具体地说，对于公用事业运营商或研究人员来说，没有实际的方法来测试新想法，例如在现实规模上测试IP或MPLS的替代方案，以获得现实世界部署所需的经验和信心。其结果是，新奇的想法没有经过检验。相反，OpenFlow框架使网络研究取得了重大进展。OpenFlow为公用事业运营商和研究人员提供了必要的可编程性和灵活性，以实现智能电网下一代通信架构的创新。这种级别的灵活性使OpenFlow能够提供MPLS的所有功能，还允许OpenFlow设备与现有的MPLS设备共存。仿真结果表明，OpenFlow的性能与多协议标签交换一样好，因此可以被认为是智能电网应用中多协议标签交换的替代方案。
Utility companies are integrating multiprotocol label switching (MPLS) technologies into existing backbone networks, including networks between substations and control centers. MPLS has mechanisms for efficient overlay technologies as well as mechanisms to enhance security: features essential to the functioning of the smart grid. However, with MPLS routing and other switching technologies innovation is restricted to the features enclosed “in the box.” More specifically, there is no practical way for utility operators or researchers to test new ideas such as alternatives to IP or MPLS on a realistic scale to obtain the experience and confidence necessary for real world deployments. As a result, novel ideas go untested. Conversely, the OpenFlow framework has enabled significant advancements in network research. OpenFlow provides utility operators and researchers the programmability and flexibility necessary to enable innovation in next-generation communication architectures for the smart grid. This level of flexibility allows OpenFlow to provide all features of MPLS and also allows OpenFlow devices to co-exist with existing MPLS devices. The simulation results in this paper demonstrate that OpenFlow performs as well as MPLS, and may therefore be considered an alternative to MPLS for smart grid applications.
