摘　　要：根据国家电网公司建设容灾中心的统一部署要求,浙江省电力公司将采用双平面方案,即在省内非省会城市建设除现有骨干网以外的骨干网第二平面。通过双平面网络的建设,既可为地市公司访问所属容灾中心、公司总部提供冗余及负载均衡链路,又可为不同业务间的负载均衡提供有力的技术支撑,从而进一步保障浙江电力信息骨干网的坚强可靠运行。与单一平面网络相比,双平面网络由于平面间的相对独立性,有效规避了网络设备和系统缺陷对网络的可用性的影响,从而具有较高的业务保障能力。According to unified arrangements of State Grid Corporation to construct disaster tolerance centers, Zhejiang Eleetric Power Company adopts dual-plane scheme to build a second plane to the existing backbone network in non-capital cities. Dual-plane network can not only provide redundant and load-balancing link for subsidiary company when they access the disaster toleranee center and headquarters, but also provide powerful technical support to the load-balancing between different businesses. Because the two planes are independent with each other, comparing with single-plane network, dual-plane network can effectively reduce the impact of network equipment and system defects to the network availability. This makes the backbone network stronger and more reliable.
